I build backend systems in Elixir, Phoenix, and OTP designed to stay correct under real-world load, and AI-powered tools and pipelines in Python. My focus: backend architecture, GS1-based traceability, and AI-driven automation — software built to hold up, not just demo well.

I founded MacDevs, a community-driven software studio and open-source home, where I ship and maintain projects in the open.
