Lead software engineer building scalable consumer and B2B web platforms, optimizing performance, and growing teams.
IndiaWhat I'm looking for
I’m a Lead Software Engineer with 7 years of experience building large-scale consumer products at Swiggy and Paytm. I’ve led a team of 10 engineers shipping features used by tens of millions of users, owning the full frontend lifecycle—from architecture and performance to infrastructure, monitoring, and team growth.
At Swiggy, I led a full tech-stack migration from a legacy React/Express SSR setup to TanStack Start with Zustand and TanStack Query, delivering 80% faster build times and 15% lower page load time. I also drove an infrastructure migration for the frontend service, cutting monthly service costs by 70%, and integrated GenAI tooling (CodeRabbit and Claude) to improve PR review quality and delivery speed. Earlier, I migrated EC2 deployments to Docker (30% infrastructure cost reduction), rebuilt internal operations tooling with Retool (80% less effort), and built design systems with Storybook and end-to-end Cypress testing—ensuring quality, consistency, and fast iteration.
