I started building mobile apps in 2015 (Android, Android TV, React, and React Native) clients for streaming platforms, EV charging networks, and logistics systems handling thousands of daily deliveries. I liked the work, but I kept bumping into the same limit: the API boundary. I was relying on other people's explanations for what happened on the other side, and I wanted to understand it myself.

That pulled me into backend systems (Node.js, then Go and Python) building services, infrastructure, and data pipelines. When I founded Ciutadel, a social network I took from zero to production, I got to work across the full stack for the first time: backend, mobile clients, cloud infrastructure on GCP, CI/CD. I wouldn't say it made me a full-stack expert, but it changed how I think about tradeoffs between layers.

Right now I'm at Forma Health, working in the healthtech space. On my own time, I've been digging into ML infrastructure (Vertex AI, BigQuery, LangGraph) trying to understand what it actually takes to get models running reliably in production.

Ten years into this, the honest summary is that each new domain mostly teaches me how much I was missing before.
