Pallavi Kumari - Portfolio
Full-stack engineer building web and AI products.
I'm Pallavi - I design, build and ship production-grade applications end-to-end, and I contribute upstream to open source. Currently exploring LLM-powered developer tooling.
01 · About
A short background
I started out automating 4G/5G test-release pipelines at Nokia and building enterprise UIs at HCL, then moved into fast-moving product engineering with a focus on AI-powered development.
Since then I've shipped production tools like VexonAI, ShiftLink and EquiGen, and had 80+ accepted pull requests across a dozen open-source projects - from reverse-proxy infrastructure to low-code platforms.
I care about ownership, clean TypeScript and shippable things. When I'm not building, I'm reading production code or contributing upstream.

04 · Open source
Open-source contributions
Actively contributing to production codebases - mostly TypeScript infrastructure, AI tooling and developer platforms. Every PR was reviewed and merged by a maintainer.
Beyond code
- Issue reporting. Open bugs, enhancements and security issues found while using - and poking at - upstream projects, so maintainers can fix real problems others hit too.
- Issue triage. On hand in open issues to test and reproduce reported bugs, write clear repro steps, and help issue openers and maintainers move things forward.
