What I'm looking for

I’m looking for a Senior Flutter role where I can own end-to-end product features, design scalable Flutter architecture, optimize performance, and build secure fintech workflows with a collaborative team.

I’m a Senior Flutter engineer with 6+ years building production mobile & web applications across fintech, insurance, e-commerce, and logistics. Most recently as an SDE-3 at Tata Nue, I owned payments and built a BFF framework powering term life insurance onboarding for 100M+ users across Android, iOS, and PWA.

I led a 6-engineer Flutter team inside a 10-person pod, delivering UPI payments and Health Term Insurance modules end-to-end. I owned the UPI experience (payment, accept/decline, UPI PIN flow, and all success/failure/pending states) and shipped a reusable native UPI plugin (Android Java + iOS Swift) behind a clean Flutter interface. I also designed and built the Backend-for-Frontend (BFF) library that consumes backend JSON contracts and renders fully-functional Flutter UI dynamically—enabling onboarding of new products without app releases.

I’m known for performance optimization and scalable Flutter architecture: I drove lazy loading, caching, and cold-start improvements, and built the analytics layer to instrument funnels and feature performance. Across teams, I mentor junior engineers through code reviews, pairing, and architecture guidance, and I’ve contributed to additional modules like Fixed Deposits and several cross-platform apps from scratch.
