Senior engineer · San José, Costa Rica · since 2015
I build production web, mobile, and AI applications — and host them on self-managed infrastructure, not AWS or GCP. Eleven years shipping across the stack.
Build + host, end to end
What I build
Senior IC delivery across the stack. Next.js, Angular, React Native, .NET Core, Node.js. AI features wired through prompt engineering and tooling I built for the team.
Where it runs
Coolify on a VPS. Postgres or MySQL on Neon. Open-source monitoring. The boring parts — TLS, backups, observability — done right. Flat monthly invoice, not hyperscaler surprise.
Why it matters
AWS, GCP, and Azure charge by the byte, by the request, by the egress. Self-managed infrastructure bills by the month. You can plan around it.
How I engage
Self-hosted application infrastructure on cost-predictable VPS — built and operated on Coolify, Postgres, and open-source monitoring. Flat monthly invoice, cancel anytime. No AWS/GCP billing surprises.
