About me

Backend · APIs · Data · Automation · AI

Hi, I'm Joaquin (Joaco), a backend developer focused on Python and the craft of clear REST APIs, robust data flows and AI-assisted features. I enjoy turning loosely defined problems into concise architectures: small services with explicit boundaries, predictable performance and solid observability. I favour simple, composable designs over fashionable complexity—versioned endpoints, typed contracts, repeatable pipelines, meaningful tests. I collaborate with teams or solo on freelance projects, bringing documentation, clean commits, CI testing and iterative delivery. If you need someone to design or reinforce a backend foundation (APIs, data processing, automation, AI integration) with maintainable quality, let's talk.
