01 ABOUT

The engineer
behind the systems.

Computer Science undergrad at NIT Jalandhar (Batch of 2026), deeply focused on Backend Systems & Distributed Architectures.

I've built AI workflow engines like Weaveflow and production-grade detection platforms like DeepTrace. I actively contribute to open-source — Google's Gemini CLI and the CNCF OpenTelemetry project — with 50+ merged PRs. Beyond the keyboard, I'm an avid chess player, applying strategic thinking to system design.
