BUILDING SCALABLE SYSTEMS.
I'm Sumit Chauhan, a
Software Engineer.
Based in India. Building what matters.
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.
