## About

I spent 10 months as a Frontend Engineer intern at HackerEarth \- a large\-scale coding assessment platform used by enterprise hiring teams worldwide\. I owned UI components from design handoff to deployment, resolved critical bugs across core assessment flows, and shipped under real product timelines working closely with backend engineers and designers\. Outside of work, I build things independently: \- OpenFrame \- image\-sharing platform, Next\.js \+ Turborepo, event\-driven Kafka pipeline, direct\-to\-S3 uploads \- PR Ninja \- LLM\-driven GitHub PR reviewer \(Next\.js, Webhooks, Redis, PostgreSQL\)\. \- use\_image\_downloader \- open\-source React hook, 400\+ npm downloads \- Tunes \- Music streaming platform with redis caching cut API latency 21% I write TypeScript\-first, think in component systems, and care about performance, reliability, and clean abstractions\. I've shipped production code, collaborated cross\-functionally, and built things people actually use\.
