Hey, I'm Yash. I'm 19, a CS student at IIT Jodhpur, and I build open source tools people actually use.

What your sponsorship funds

Most of it is breakscale, a system design simulator that runs the diagram instead of drawing it. Drag the traffic up and watch real queueing behaviour emerge from a discrete-event engine: p99 climbing before anything errors, a retry storm that is healthy at 80 requests per second and collapsing at 85. It's MIT licensed, runs in the browser with no account, and crossed 1,000 GitHub stars in its first week with 11 contributors sending real fixes.

Sponsorship covers domains and infrastructure for breakscale and its docs, and buys the time to review contributions, write per-example teaching pages, and keep the simulator honest. Workers IO (YC F26) is the title sponsor; individual sponsors fund the parts a company doesn't.

Other things I maintain

  • Photon, a NASDAQ ITCH feed handler in C++20
  • cutback, version control for Kdenlive projects
  • wallglow, a Bluetooth LED strip that follows your wallpaper
  • Grindmap, LeetCode questions ranked by which companies ask them

I completed Google Summer of Code 2026 with KDE: three Kdenlive widgets merged and shipping in 26.08.

Every bit helps, and thank you for considering it. 💖

Reaching this goal covers the domains and infrastructure behind breakscale, my open source system design simulator, and its docs, and buys time to review contributions and keep building the tools I share publicly.
