What I'm looking for

I'm looking for an opportunity to build scalable backend and full-stack products, contribute to REST APIs and data systems, and grow through hands-on work in software engineering and machine learning.

I've built and shipped an ML-driven governance analytics platform that processes lakh-scale Aadhaar authentication records, detects operational irregularities, and delivers severity-ranked decision-support reports.

For the Aadhaar Intelligence System, I built Node.js, Express, Prisma/PostgreSQL REST APIs, an anomaly-detection pipeline using Z-Score, IQR, and Isolation Forest, and a Mapbox geographic heatmap. I also implemented JWT and Google OAuth authentication and deployed the product across Render and Vercel.

On DefendX, I owned the React frontend for an AI-assisted SOC dashboard, including live incident monitoring, a WebSocket-powered telemetry console, and a paginated reports experience. I'm a final-year Computer Science student with hands-on full-stack, backend, database, and machine learning foundations.
