I build web platforms that scale — and teams that ship.

15+ years across TypeScript, React, Node.js and AWS. Lately: live-streaming architecture, AI-assisted engineering workflows, and mentoring engineers.

Hi, I'm Jonatan.

I'm a staff-level full-stack engineer and technical lead based in Buenos Aires, working with teams in the US and beyond. I started fixing computers at a help desk in 2009; since then I've spent 15+ years building web platforms — the last six leading a team of seven engineers shipping streaming products used around the world.

I care about clean architecture that survives contact with reality, tests that describe behavior instead of implementation, and lately — how AI genuinely changes the way software gets planned, written and reviewed. That's what I write and make videos about asiencodev.
