Software Engineer focused on scalable Flutter/Dart products and performance optimization.
IndiaWhat I'm looking for
I’m a Software Engineer who builds and improves customer-facing products with a strong focus on performance, reliability, and user experience. I’ve worked across mobile and backend-facing systems, turning complex problems into measurable outcomes.
At Cropin, I resolved critical performance bottlenecks by migrating Drift SQL database sync from synchronous to asynchronous using isolates—cutting sync latency by 50%+ and making the experience smoother. I also engineered a user feedback feature that improved engagement for 6,800+ users by 13%, and I diagnosed recurring errors to achieve a 96% reduction in monthly recoverable error events.
At Amazon, I contributed to the Kindle Unlimited India application used by 3 million+ customers. I redesigned the subscription renewal failure fixup page to increase renewal for 300,000 users, and I engineered and optimized recurring payment processing for 120,000 users using the Horizonte framework.
Earlier, at Bottomline Technologies, I developed Global Search, Invoicing, and Similar Payments to improve retention, and I strengthened engineering quality through behavior-driven development—reaching 100% test coverage and reducing critical bugs. I enjoy collaborating across teams, conducting thorough code reviews, and mentoring by turning feedback into maintainable, high-performing systems.
