I helped run Sanic for a while (former core dev) and got a public "shout out to @vltr for all his work" from the sanic-jwt lead maintainer. That one's archived in the docs, which is nice. I also authored a handful of PyPI packages that did their job before the ecosystem caught up.

These days I'm the sole backend voice at a US workforce-management SaaS, running the multi-quarter roadmap that keeps the lights on. I treat Claude Code as a platform to engineer around (hooks, skills, MCP servers, agents), not just to prompt.

Off-keyboard: CNC, 3D printing, wood-carving, GNOME Shell tinkering, Arch Linux as a hobby, craft brewing, F1, and a strong opinion that insects and frogs deserve more love.
