All that happened at the Cypher AI Conference 2025

At Mercari India, continuous learning isn’t a box to check – it’s part of how we grow. Recently, our team had the opportunity to attend Cypher AI 2025, one of India’s largest and most forward-looking conferences on artificial intelligence. Across keynotes, panels, debates, and booth interactions, one thing was clear: AI is no longer just a technical revolution, it’s a human one. One standout session, “Upskilling for an AI Future – Blending Tech Prowess with Human-Centric Skills,” delivered by a senior engineering leader at LinkedIn, reframed how we think about growth. The message was bold: in the AI era, degrees are good, but dynamic skills are essential. The future will reward those who stay curious, adaptable, and committed to learning. It also reminded us that while AI and data skills are in high demand, they need to be paired with empathy, creativity, and communication to create meaningful impact. As India rapidly approaches 70% AI adoption, the stakes and opportunities are higher than ever. A thought-provoking debate titled “Generative AI and Knowledge Work – Job Enabler or Disruptor?” sparked lively discussion and sharp insights from CXO-level leaders. The key takeaway was that the shift to an AI-native organization is not about replacing people, but about transforming how work gets done, with AI as a collaborator, not a competitor. Several technical deep dives throughout the day pushed our understanding even further. In a session titled “Co-Intelligence = IA to the Power of AI” by Tredence’s Soumendra Mohanty, we explored how to design “ambidextrous” AI systems that embrace both structure and creativity. He emphasized the need to build for ambiguity and incorporate human-in-the-loop oversight. His framework broke down GenAI integration across workflows like content creation, customer engagement, and data insights, using specialized agents to simulate real-world roles with precision.… <a class="more-link" href="https://about.in.mercari.com/news/all-that-happened-at-the-cypher-ai-conference-2025/">Continue reading All that happened at the Cypher AI Conference 2025</a>

Migrating Coupons from Monolith to Microservice

Our JourneyBackground: The Heart of Our Platform Coupons are central to our platform, driving user engagement and retention through credit points and discounts. Historically, this critical system resided within our extensive PHP monolith, deeply integrated with almost all major modules like accounting, payment processing, checkout, listings, and item management. While this architecture initially facilitated rapid iteration, its limitations became apparent as our product and team grew. Why We Decided to Migrate The coupon domain’s deep entanglement with critical modules increasingly hampered agility and introduced operational risks. As some parts of our system transitioned to microservices while others remained in the monolith, complexity mounted. Our key motivations for this migration included: Technical Debt: The monolith’s increasing complexity hindered development and heightened regression risks. Scalability: Coupon processing needed to accommodate a growing user base and higher loads. Reliability and Ownership: We needed clearer data ownership boundaries and a straightforward path for performance optimization. What This Blog Post Covers In this post, I will detail the approach we adopted for migrating our coupon system to a robust, scalable microservice, including our methodology, the challenges we encountered, and the lessons we learned.The Challenges Migrating a critical domain like coupons involves more than just moving code. Here’s what made this journey particularly complex: Tight Coupling: The coupon domain’s pervasive connections to accounting, payments, listing, and item screens meant that moving one piece affected many others. Always-On Expectations: Our services needed to remain continuously available without significant downtime or interruptions. Data Consistency: The migration demanded meticulous management to prevent any coupon, transaction, or reward notification from being missed. Scalability: The new architecture had to match or surpass the original system’s scale. Performance: Achieving the monolith’s native speed despite additional network hops was a significant hurdle. Unclear Ownership: Ambiguities regarding endpoint and database ownership required resolution before… <a class="more-link" href="https://about.in.mercari.com/news/mercari-india/migrating-coupons-from-monolith-to-microservice/">Continue reading Migrating Coupons from Monolith to Microservice</a>

Inside The Live2Test 2025: The Premier Online Conference for Software Testing – Udit Gattani

The Live2Test 2025 tech panel explored the rapidly evolving technological landscape of software testing, focusing on the influence of Artificial Intelligence and other breakthrough technologies. The conversation delved into the transformation of traditional testing workflows, the rise of AI-augmented approaches, and the crucial role testers must play in navigating changes across the industry. Amidst the excitement about cutting-edge tools like ChatGPT and blockchain, the panel delivered an honest message: Testers who fail to adapt and embrace these innovations will risk falling behind. More than ever, testers are expected to graduate from repetitive tasks to high-level problem-solving, risk assessment, and strategic thinking. Key Takeaways 1. The Tester’s Role is Transforming The iconic manual tester role is rapidly becoming outdated. While this doesn’t mean testers are being replaced, their roles are undeniably evolving. Testers must now think beyond execution and focus on bigger-picture responsibilities, such as risk profiling, evaluating AI model behavior, and designing prompts for AI systems. These emergent skills are what will define the future of testing, leaving behind the “button-clicker” mindset of the past. 2. AI is Just a Tool, Not a Cure-All AI’s ability to accelerate and automate aspects of testing is undeniable, but it’s neither magic nor a one-size-fits-all solution. Tools like ChatGPT, AI-based test case generators, and coding copilots are only as effective as the humans directing them. Over-reliance on these tools—without proper judgment—can result in flawed test cases, defective releases, and even security risks. 3. Upskilling in AI is Non-Negotiable As AI becomes a critical part of software development and testing cycles, training in AI concepts is no longer a “nice-to-have.” Organizations must empower their teams with skills in AI fundamentals, risk detection, prompt engineering, and ethical usage guidelines to keep pace with industry demands. A highly trained, AI-capable team will also help ensure that… <a class="more-link" href="https://about.in.mercari.com/news/mercari-india/inside-the-live2test-2025-the-premier-online-conference-for-software-testing-udit-gattani/">Continue reading Inside The Live2Test 2025: The Premier Online Conference for Software Testing – Udit Gattani</a>

A Day of Purpose: A Heartfelt CSR Visit by Mercari India

There are experiences that go beyond words, quietly humbling, deeply moving, and filled with perspective. Our recent visit to Thayi Mane- Children’s home in Bangalore, was one such moment for the Mercari India team. Thayi Mane provides a nurturing environment for children who are either orphaned or come from families unable to support them. The home not only takes care of their education but also focuses on their discipline, values, and emotional well-being. It is a space built on structure, compassion, and hope. Our visit began post-school hours, as we waited for the children to return from their classes around 3:30 PM. The visit was centered around spending quality time with the children and engaging them in a creative activity. We distributed drawing charts, sketch pens, and colours, encouraging each child to express their imagination freely. What followed was a vibrant, uninhibited display of creativity that gave us a glimpse into their unique thoughts and dreams. As the activity came to an end, we gathered for evening snacks, which were sponsored by Mercari India. Sitting together in a shared space, we exchanged stories, smiles, and conversations that reminded us how powerful simple moments can be. This visit was a heartfelt reminder that real impact doesn’t always come from grand gestures, but from showing up with sincerity and being present. Spending time with the children at Thayi Mane left a lasting impression on all of us, and reinforced our commitment to building meaningful connections with the community around us. -Smriti Singhal Stay tuned for more stories, lessons, and reflections as we continue to learn and grow together.

Two Sides of the Desk: An Intern-Mentor Journey ft. Smriti and Jesuine at Mercari India

Welcome to Two Sides of the Desk, a blog series where we share the unique experiences, challenges, and triumphs of interns and their mentors. This blog explores the dynamic relationship between mentor and mentee, offering insights from both sides of the desk. Whether you’re a seasoned mentor, a budding intern, or simply curious about the mentorship journey, our stories and reflections aim to inspire, educate, and foster a deeper understanding of this transformative partnership. Mentor: Smriti Singhal Designation: HR- Mercari India How do you approach balancing guidance and autonomy for your interns to ensure they’re both learning and contributing meaningfully to projects? My approach has always been to create a balance between structure and space. I made sure she had clarity on expectations, but I didn’t micromanage. I allowed her to explore, make mistakes, and come back with questions even if it was the same question twice. I believe real learning happens when someone feels safe enough to try, fail, and ask again. That space helped her grow, and over time, she not only delivered with consistency and confidence, but also began taking full ownership of her work with remarkable attention to detail and accountability At the same time, I also make it clear that the freedom I offer shouldn’t be taken for granted. With autonomy comes responsibility. I try to instill that balance of being self-driven but also accountable so she understands that trust is something we build and maintain together. The goal for me is always to make someone confident in their own voice, not just efficient in a task. Can you provide an example of a particularly challenging situation you’ve encountered while mentoring an intern, and how you navigated it to ensure their growth and success? When Jesuine first joined, she came across as quite introverted and found… <a class="more-link" href="https://about.in.mercari.com/uncategorized/two-sides-of-a-desk/">Continue reading Two Sides of the Desk: An Intern-Mentor Journey ft.

From DNS Failures to Resilience: How NodeLocal DNSCache Saved the Day, Sanu Satyadarshi

I am Sanu Satyadarshi, part of the Platform Engineering division at Mercari, Inc. Platform Engineering provides a cost-effective, safe, and easy-to-use multi-cloud infrastructure service for all engineering teams to make and scale bets. This article discusses the DNS-related challenges encountered at Mercari on our Kubernetes clusters and the significant improvements achieved by implementing Node-Local DNS Cache. By optimizing DNS traffic and reducing errors, we enhanced system reliability and scalability, preventing production outages caused by DNS failures. Key Takeaways Reduced DNS calls to kube-dns by 10x, decreasing network overhead and inter-service communication costs. Lowered DNS query rates by 93% for services on the cluster. Achieved a 10x-100x reduction in DNS-level errors, improving system resilience. Eliminated the “failed to refresh DNS cache” errors, mitigating a frequent source of incidents. DNS on Kubernetes: The Elephant in the Room Domain Name System, more commonly known as DNS an extremely critical component in the internet infrastructure. This is the tech that allows your web browser to find the actual IP address of a website when you type example.com in your browser. DNS in itself is a highly complex topic, and understanding it requires a book(or two) on its own. Like any network infrastructure, Kubernetes depends on DNS to resolve service names like [service name].[namespace].svc.cluster.local and other names to IPs and allows communications among services and the external world. From the role of DNS in Kubernetes, you can imagine that any DNS failure or degradation can quickly escalate to increased latency, network congestion, and even complete outages. On Kubernetes, DNS is installed as a kube-dns deployment running on the kube-system namespace. Specifically at Mercari, it comes pre-installed with our managed GKE clusters for service discovery and name resolution across the clusters. kube-dns on Kubernetes allows multiple configurations using the configmap that can be used to change various parameters like ndots, etc. As kube-dns is responsible for resolving all… <a class="more-link" href="https://about.in.mercari.com/news/mercari-india/from-dns-failures-to-resilience-how-nodelocal-dnscache-saved-the-day-sanu-satyadarshi/">Continue reading From DNS Failures to Resilience: How NodeLocal DNSCache Saved the Day, Sanu Satyadarshi</a>

Inside the manager’s mind : Manjunath Sagar

Welcome to inside the manager’s mind — a space where leadership meets reality. Explore the highs, lows, and everyday decisions that shape teams and drive success. From strategic thinking to people management, this blog offers raw insights and practical wisdom for those leading or aspiring to lead. In this feature we’d like you to meet Sagar! Sagar : At Mercari India, rapid expansion is more than just scaling numbers—it’s about intentional leadership that fosters clarity, unlocks potential, and nurtures an empowered culture. For me, effective management isn’t just about driving performance; it’s about guiding with steadiness, leading with empathy, and creating a foundation of trust. As we continue to grow, I find myself leaning on a set of principles—some expected, some unconventional—that have shaped the way I support my team. Whether it’s welcoming new talent, refining HR initiatives, or championing individual growth, these values remain at the core of how I lead. 1. Anchor in Calm Amidst Chaos Change fuels innovation, but it also brings uncertainty. In high-growth environments, teams don’t just look to their leaders for solutions—they look for steadiness. My guiding principle: My calm creates their safety; my clarity gives them direction. What I do: Every one-on-one starts the same way—with a genuine “How are you doing?” before diving into work. This small act of care fosters trust and sets the tone for a culture of support. 2. Empower Through Context, Not Control Momentum thrives when people feel empowered, not micromanaged. Providing context allows teams to move with confidence and make decisions independently. What I do: During onboarding and team syncs, I take extra time to explain the reasoning behind our goals—not just what we’re doing, but why it matters. The result? A team that thinks critically, acts decisively, and continuously grows. 3. Normalize “I Don’t Know” Leadership… <a class="more-link" href="https://about.in.mercari.com/news/mercari-india/inside-the-managers-mind-manjunath-sagar/">Continue reading Inside the manager’s mind : Manjunath Sagar</a>

From Day 1 to Day 100 at Mercari: A Journey of Growth and Memories ft. Aashutosh Agrawal

When I first heard that Mercari was coming to our campus, I was excited but also a little nervous. It felt like a huge opportunity — and looking back now, I realize it was one of the best experiences I’ve had so far. The Beginning: Placement Journey The process kicked off with an Online Assessment (OA) consisting of two medium-level DSA questions. It tested not just speed but also our ability to think critically under pressure. After clearing the OA, I had my technical interview with Rajat, where we discussed coding approaches, problem-solving techniques, and a few OS and computer science fundamentals. What stood out was how the conversation was more collaborative than a “grill” session. Next was the managerial round with Atif, where the focus shifted towards understanding my motivations, how I work in teams, and cultural fit. It was refreshing to have an open, honest conversation rather than just technical questions. Finally, I remember the day I received the confirmation letter — a mix of relief, excitement, and pride. It was the start of something new. Day 1: A Warm Welcome The first day at Mercari was truly special. From being welcomed with a thoughtfully curated goodies kit to meeting fellow interns and full-time employees during the onboarding, everything felt smooth and personal. The highlight was the team dinner later in the evening — good food, casual chats, and laughter with people who, until a few hours ago, were complete strangers. January: Settling In, Learning the Foundations, and a Special Cricket Memory January was all about getting familiar with Mercari’s world and setting a strong foundation. We started with our common onboarding sessions — diving into essential tools like GitHub, Confluence, Slack, JIRA, understanding Mercari’s overall architecture, and exploring key repositories. These sessions were packed with valuable insights… <a class="more-link" href="https://about.in.mercari.com/news/intern-series/from-day-1-to-day-100-at-mercari-a-journey-of-growth-and-memories/">Continue reading From Day 1 to Day 100 at Mercari: A Journey of Growth and Memories ft.

My Work Trip to Japan: Insights, Observations & Key Takeaways

At the end of January 2025, my colleagues from the XB Supply team and I finally visited Mercari’s Tokyo office after collaborating remotely with the Japan team for nearly six months. For two of us, including myself, it was our first visit to the Tokyo office after being at Mercari for over 1.5 years, while others had visited before. It was a great opportunity to move beyond Slack profiles and Google Meet headshots and connect with our past and present colleagues in person. Work, Strategy & Strengthening Collaboration The primary purpose of our trip was to participate in business strategy and feature planning for the year, focusing on XB (Cross Border) Supply. Another key objective was to strengthen collaboration by meeting colleagues from various teams working on the XB Supply mission, as well as frequent collaborators like the Shops(B2C) team. Building trust, improving communication, and fostering openness were crucial as we transitioned into the “Back to Startup” phase. In a startup environment, strong personal connections and close collaboration are essential. During our visit, we had the opportunity to meet and collaborate with several key teams, including the XB Supply product team, business development, design, analytics, marketing, and executives. We also connected casually over lunch with other XB engineers. A major highlight was a high-level OKR discussion with the entire Shops division, followed by a dinner with some of the Shops team members. One of the key moments of the trip was a full-day workshop where the XB Supply JP and IN teams came together to brainstorm ideas for the initiative. I also had the chance to reconnect with colleagues from my previous teams (Team Orion and LTVG). Beyond these meetings, it was insightful to physically attend the XB All-Hands and Japan All-Hands, experiencing the energy and alignment in person.

Inside the manager’s mind : Gaurav Bansal

Welcome to inside the manager’s mind — a space where leadership meets reality. Explore the highs, lows, and everyday decisions that shape teams and drive success. From strategic thinking to people management, this blog offers raw insights and practical wisdom for those leading or aspiring to lead. In this feature we’d like you to meet Gaurav Bansal! Gaurav Bansal: As a manager, my constant focus is on solving challenges that my team faces. The key is staying aware of these challenges, acknowledging them, and taking decisive action. Let me share how I approach some common management challenges. Building Cross-Functional Collaboration When my team expanded from client-only developers to include Backend developers, I noticed collaboration gaps emerging. While client developers had strong relationships from working together for a year, the integration with Backend developers needed attention. To address this, we focused on creating a collaborative environment through regular team activities, including recent bowling and dinner events that helped break down barriers and foster natural connections. We’ve made significant strides in fostering technical understanding between teams. Our backend team now regularly shares insights about API performance, which has led to client teams implementing more effective loading states. Similarly, when client teams demonstrate user interactions, it helps backend developers design more intuitive API endpoints. These exchanges have transformed our team’s mindset from “That’s not my job” to “How can I help?” Maintaining Team Motivation Recognition plays a crucial role in keeping the team motivated throughout the development lifecycle. We celebrate joint wins and team contributions, making sure everyone feels valued for their unique contributions. Mercari’s employee-centric culture and various club activities provide additional avenues for engagement and motivation.Work-life balance is another cornerstone of our approach. We’ve implemented flexible working hours, understanding that some team members are early birds while others peak later in… <a class="more-link" href="https://about.in.mercari.com/news/inside-the-managers-mind-gaurav-bansal/">Continue reading Inside the manager’s mind : Gaurav Bansal</a>
