About

I like owning a feature from end to end — the Compose screen, the API it calls, and the table underneath it.

As an SDE intern at Fin Tradify I worked on two production Android apps on Google Play: twelve Compose screens, eighteen API integrations, an offline-first data layer with Room, and about 15% fewer crashes by the time I left. These days I lead the development team at CSI VIT-AP, where our app, CSI Events, runs the chapter's hackathons.

History

Career history as a git log: B.Tech CSE at VIT-AP; first Compose apps; SDE intern at Fin Tradify (Jun 2025 – Jan 2026), two Android apps shipped to Google Play; patient management microservices; lead of the CSI Development Team; CSI Events in use at CSI VIT-AP; graduating in 2027.

Selected work

CSI Events · API The event app CSI VIT-AP runs its hackathons on: teams join with a code, judges score from their phones, results go live when the organizer publishes them. Kotlin, Compose, Spring Boot, PostgreSQL
Patient Management Five Spring Boot services behind a JWT gateway. Kafka carries events to analytics, billing talks gRPC, and AWS CDK deploys it all to ECS Fargate. Spring Cloud, Kafka, gRPC, AWS
Fact Knowledge Layer Reads PDFs, pulls out facts with an LLM along with the exact quote behind each one, and flags where documents agree or contradict. Java, LLM
