About

I’m a Software Engineer at Paytm, building large-scale fintech products used by millions. I work across the stack with React, TypeScript, Node.js, Java, AWS, and scalable system design, with a strong focus on backend engineering and performance. At Paytm, I’ve taken end-to-end ownership of products across both frontend and backend. One of my key projects has been the latest Split Bills (HisabKitab) experience, where I helped design and build the system end-to-end, including scalable APIs and a triple-layer architecture with versioned split metadata, an append-only ledger, and materialized net balances. I enjoy solving problems around scalability, system design, API architecture, database optimization, performance, and reliable distributed systems. I’ve also improved application performance by 25–35% and worked on building reusable components and better developer workflows. My cloud and infrastructure experience includes AWS (EC2, S3, Lambda, ECS, EKS), Docker, and Kubernetes. I’m also exploring AI engineering, LLMs, and agentic workflows, with an interest in building intelligent, production-ready applications. Always curious, always learning, and always looking for opportunities to build systems that are scalable, reliable, and genuinely useful.
