02 BACKGROUND

The engineer
behind the systems.

Software engineer and B.Tech Computer Science graduate from NIT Jalandhar, deeply focused on Backend Systems & Distributed Architectures.

I've built and shipped DeepTrace, an AI image detection platform, and HerbiGPT, a retrieval-grounded Ayurveda chatbot. In open source I've landed fixes in TensorFlow and Apache Arrow and contributed to Google's Gemini CLI and CNCF OpenTelemetry, with 50+ merged PRs in total. Away from the keyboard I play a lot of chess, which has shaped how I think about system design.
