Sarwagya Singh — Software Engineer
I’m Sarwagya Singh. I’m a software engineer at Actimi, based in Ludwigsburg.
Software Engineer at Actimi, where I build the software layer around continuous patient monitoring — devices, feeds, and the boring plumbing that keeps clinical data honest. Before that, and still on the side, I co-founded Vestcodes, a small studio building tools for people who ship on the internet.
I like small teams, small dependencies, and interfaces that stay legible after the third person has touched them.
Most of what I release lives under oss.sarwagya.wtf — MIT-licensed, kept intentionally small, and documented like someone else will maintain them (usually me, six months later).

Live experiments and browser-side demos run at local.sarwagya.wtf — most recently a WebRTC demo built on top of handoff and durable-local.
I write in three rooms. Engineering long-form ships to eng.sarwagya.wtf when I’ve actually shipped the thing it’s about. Opinions — sharper, less careful — go up at bakaiti.sarwagya.wtf. Everything else lives as notes in sarwagya.wtf/margins — half-thoughts, unfinished on purpose.

I studied at the Technical University of Munich and Saarland University. A public trail of the research-adjacent work is on my ResearchGate profile.
A previous life. I’m credited as additional crew on Panchayat and Bhakshak. The full record is on IMDb (nm16137305).
The same person, in more places than is probably wise:
If you searched my name and landed on a rated player: that’s a different person. Sarwagya Singh Kushwaha is a FIDE-rated chess player from Madhya Pradesh, India. I’m not him. I don’t play rated chess, I don’t live in Madhya Pradesh, and the only openings I care about are the ones in main.
