Vinit Kumar

Principal Engineer building backend systems, developer tools, and open source software.

I build practical software for people who care about reliability, performance, and maintainable systems. Most of my open source work sits around Python, Rust, Go, TypeScript, APIs, CLIs, databases, and developer workflow.

Blog • LinkedIn • Twitter • Email

Start Here

  • json2xml
    A Python JSON-to-XML library with an optional native Rust extension. The current benchmark shows the Rust path running 57-129x faster than pure Python, with automatic fallback when native wheels are unavailable.

  • json2xml-go
    A Go implementation and CLI for shell-based JSON-to-XML conversion, useful for batch jobs and data pipelines.

  • json2xml-zig
    A Zig implementation exploring fast native CLI startup and throughput for the same conversion problem.

Together, these projects are my current open source lab for performance work across Python extension modules, native CLIs, packaging, benchmarks, and developer-facing documentation.

What I Focus On

  • Backend architecture for products operating at meaningful scale
  • Python, Rust, Go, and TypeScript systems where performance matters
  • Developer tools, editors, CLIs, automation, and workflow design
  • Open source projects that are small, practical, tested, and well-documented

Featured Work

  • node-twitter
    A Twitter-style application built with Node.js and TypeScript, useful as a full-stack architecture reference project.

  • chatbot
    A compact chatbot experiment built with C and Zig, exploring systems-level implementation choices.

  • oscura-vim
    A Vim port of the Oscura theme.

If you are working on backend scale, Python/Rust performance, CLIs, or developer tooling, I would be happy to compare notes.
