I’m a CSE 2026 graduate who’s shipped 3 production-deployed full-stack apps with React + Node.js + PostgreSQL, plus a live labor marketplace integration using the Gemini API. I’ve independently built and maintained working systems that are already running in production, not just prototypes.

I focus on backend reliability and security: I built JWT-secured REST APIs with bcrypt authentication, added centralized input validation middleware, and used parameterized queries to prevent SQL injection. I also automated CI/CD using GitHub Actions so builds stay healthy as features evolve.

I enjoy crossing boundaries to deliver real outcomes, including a cross-runtime Node.js/Python prediction API that returns delivery mode predictions with confidence scores using a Random Forest model. I also brought Gemini REST API features into an Android marketplace app, designing a centralized FirebaseRepository layer with OTP/email auth, ownership-scoped writes, and default-deny Firestore security rules.
