Software Architect — I design systems that don't fall apart.
The AsyncAPI emitter Swiss Post adopted, a multi-module CQRS + Event Sourcing framework, and the open-source tooling around them.
Every library exists because the alternatives were abstractions I couldn't trust.
| Project | What It Does |
|---|---|
| typespec-asyncapi | The missing AsyncAPI 3.1 emitter for TypeSpec — adopted by Swiss Post |
| go-cqrs-lite | CQRS + Event Sourcing for Go — a composable multi-module library, without the framework tax (proprietary) |
| cqrs-htmx | Wires go-cqrs-lite commands and queries to HTMX UIs — Casbin auth, CSRF, and SSE built in |
| templ-components | 97 server-rendered Go components — templ + HTMX + Tailwind v4, dark mode and CSP built in |
| emeet-pixyd | Linux daemon that makes the EMEET PIXY and PIXY 2K dual-camera AI webcams actually usable — PTZ, privacy-first |

You have a system that needs to work.
I build systems that work.
Let's talk.
