At Tomsawyer Technologies Pvt. Ltd., I led the rebuild of the flagship fleet-management mobile app, migrating it from Flutter to React Native (Expo). I delivered full-stack features across a Node.js/Express backend, the mobile app, and a React analytics dashboard.

I also improved performance and data accuracy by optimizing database queries, adding caching for location and metadata lookups, and refining telemetry and analytics data flows. Earlier, I contributed to the Airavat app and built its Next.js admin dashboard at BSP Sparton Pvt. Ltd.
