Full-stack developer with a builder's bias. I like starting things from scratch, launching fast, and owning the outcome end to end. Self-taught by habit, building whatever is interesting.

About

The Story

I made the jump into tech in 2023, after a few years in product management and bootstrapping small businesses. What carried over is the way I like to work: build from scratch, launch fast, own the outcome.

Mostly self-taught, my downtime goes into fundamentals and side projects. Lately I've been going deep on machine learning, and the slow battle with my own attention span. 🙊

When I'm not coding I work on my jab and cross on the punching bag, run zone-2, do calisthenics, and throw the occasional pot from clay. 🥊

Now

Senior Software Developer at Synapxe, building HealthHub Plus.

Teaching myself ML, plus a steady stream of side projects.
