Software Developer
I develop and support government systems, work on banking integrations, and build web apps with .NET, Node.js, and React.
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.
