Software developer based in Panama City

I build APIs, microservices, and integrations for real businesses — from banking systems to government projects. I'm comfortable jumping between stacks (Node.js, .NET, PHP, React) and I build with AI tools every day, from coding assistants to AI-powered data pipelines.

Outside of work, I built and run BookingYouNow, a booking app I designed, coded, and deployed on my own. I also take on freelance projects when I have time.

BookingYouNow

A SaaS booking platform I built alone, from idea to production. Users book appointments online in real time, with automated reminders and workflows powered by n8n. Live and running on my own server.
