I build software that keeps running after the demo.

Software engineer, 15+ years across Argentina, New Zealand and Spain. Backends, integrations, and lately my own product on infrastructure I run myself.

Live

Staysy

An app-free guidebook for short-term rental hosts. I'm the founder and the whole engineering team: product, build, billing, releases. It's a Go and PostgreSQL app with server-rendered htmx pages, a guest guide that works offline, an LLM assistant running on my own hardware, and a separate Go console for releases, alerts and backups.
