About

Backend engineer with 3.7+ yoe, currently at Razorpay. I think in systems before I think in code — how data moves, where it breaks, and what it costs when it does. My interest sits at the intersection of distributed infrastructure, fintech reliability, and increasingly, AI-native engineering. I'm drawn to problems where the architecture has to evolve without the system going down — and to tooling that makes engineers faster without making them dependent. Lately I've been exploring where agentic workflows and multi-agent systems start to reshape how software gets built, not just what it builds.
