I build fast, scalable web and mobile applications that help businesses grow. 4+ years delivering production-ready software for companies in Colombia and beyond.
About Me
I'm a Full Stack Developer based in Cali, Colombia, with 4+ years of professional experience building web and mobile products used by real businesses and real users.
My core stack is React, React Native, Node.js and TypeScript, with solid experience in REST and GraphQL APIs, payment gateway integrations, and cloud deployments on AWS. I've led migrations from legacy codebases, built microservices, and shipped mobile apps from scratch.
I work with both companies looking for a reliable engineer and entrepreneurs or small businesses that need a website or web app built right the first time. If you have a project in mind, let's talk.
