I'm Sumit Chauhan, a Software
Engineer.
Based in India, solving complex problems with clean code.
About.
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 RAG assistants like HerbiGPT. I heavily contribute to open-source — primarily Google’s Gemini CLI and the CNCF OpenTelemetry project. Beyond the keyboard, I'm an avid chess player applying strategic thinking to system design.

Experience & Contributions
A timeline of my professional experience and key open-source contributions.
Professional Experience
Teaching Ninja
Mentoring undergraduate students in Data Structures & Algorithms, Competitive Programming, System Design, and core Computer Science fundamentals. Conducting coding sessions, guiding problem-solving approaches, and supporting hands-on learning to build strong software engineering foundations.
Open Source Contributor
These are some of my meaningful, production-grade open-source contributions that involved real code reviews, CI pipelines, and collaboration with maintainers.
OpenTelemetry (CNCF Project)
- Emit warning when TraceIdRatioBasedSampler is used as child sampler
- Added a spec-required compatibility warning at configuration time without changing runtime behavior.
OpenTelemetry (CNCF Project)
- Clarify suppressed warnings in API common module
- Improved maintainability by documenting intentional warning suppressions. No functional changes.
Google - Gemini CLI
- Support GOOGLE_CLOUD_PROJECT_ID fallback
- Added a backward-compatible environment variable fallback, improving developer experience across platforms.
