A few things I’ve made.
I’ve worked on many projects over the years. These are the ones not covered by NDA and that I can publicly share.

PVX
One of the first implementations of PASETO written in Go. An alternative without any of the many design deficits that plague the JOSE standards.

Warnly
When Sentry blocked Russia due to sanctions, I confidently decided I could build my own Sentry in a couple of days. Warnly is what happened when that joke became production.

Compactum
A routing engine written in Rust that, in my opinion, is far better than the existing options. It will never be open source, because I don’t like what LLMs have done to SDLC.

Dracoria
What programmer has never wanted to make their own game? Dracoria is a browser RPG in the spirit of D&D, where winning sometimes requires higher math.
