What I'm looking for

I'm ready to contribute to a product engineering team.

I built DevInspect, an AI-powered code review platform that runs analysis with a locally hosted LLM and exposes 22 REST endpoints. In testing, it analyzed 15 submitted code diffs and reduced estimated manual review time by 40%.

I also developed SecureAuth, a Spring Boot authentication service with JWT and Redis-backed refresh token management, and Grocify, a mobile retail app with Stripe payments and automated order workflows. Across these projects, I’ve worked with REST APIs, PostgreSQL, and cloud-ready containerization.
