What I'm looking for

I’m looking for a team where I can build and ship production-ready full-stack features, improve API performance, and develop GenAI tools that solve real problems—while learning from strong engineering practices and measurable impact.

I’m a BCA student building production-ready systems with a focus on scalable backend APIs, performance optimization, and GenAI-powered tools. Through a Full-Stack Development Internship, I developed and deployed a membership management platform with role-based access control, full CRUD, and an Admin Portal—supported by secure authentication flows and Cloudinary integration.

I’ve also contributed to a large-scale OpenTelemetry Java codebase, delivering production-ready changes that passed 92+ CI checks with zero regressions. My work improved trace filtering accuracy by ~20% and reduced debugging effort by ~15% through cleaner attribute mapping and validated unit tests, and I’m now applying the same engineering mindset to products like a Chrome extension automating LeetCode tracking and an AI resume optimizer that parses PDFs with PDF.js and improves keyword analysis.
