About

i build products end to end, from the postgres schema to the pixel. right now i build the tech at chalyaaar, a fitness-first events company in bangalore. we run events across the city. real tickets, real payments, real people turning up at 6am. we're small and somehow already in profit. i own the platform, so that's registration, payments, qr check-in on the day, and an outreach service that finds sponsors, works out who to email, writes the email and actually sends it. the other thing i do sits a lot lower down. i put linux on my acer laptop and the keyboard lighting just didn't work. acer had moved it to a separate chip that none of the existing tools talk to, so they all happily accept every command and then do nothing at all. so i built kbrgb, which drives the chip directly. it's on the AUR and PyPI now, people with the same laptop just install it, and four of my patches to other people's linux tools have been merged so far. i've been building on llm apis since early 2026. the four-agent setup in claribb, and the provider layer in chalyaaar's outreach service, where switching models is a config change instead of a rewrite. i work that way day to day too, in claude code, codex, gemini cli, cursor and copilot. three packages on npm, one on PyPI. right now i'm going lower still and learning rust and docker properly, because the tools i love most are the ones i understand all the way down. scaler school of technology '29, plus a parallel bsc in cs from bits pilani. i do all of this from a terminal on arch linux, btw, inside neovim.

Work experience

Chief Technology Officer at chalyaaar, Apr 2026 - Present · 6 mos, Bangalore Urban, Karnataka, India, Fitness-first events and run-club company. I own the product and the stack across eight internal apps. Built the platform we actually sell tickets on, events, registration and payments, on Next.js 16 with Neon Postgres and Cashfree. Real events across Bangalore, and the company is profitable. Runner check-in works off a QR scan, and volunteers sign up through a separate flow on Supabase. Went back over the checkout path and fixed what was weak: rate limiting per IP, Cashfree webhook signatures verified rather than trusted, schema migrations no longer running on every request, and the PII columns we were collecting but never using are gone. Wrote the sponsorship outreach service: it finds leads, researches them, decides which are worth contacting, drafts the email and sends it. 2,400 lines of Python on FastAPI. Which model it uses is a config value, so switching providers costs nothing. Sending live from a verified domain since June 2026.
