About
I’m a Frontend-focused Full Stack Engineer based in Colombia, delivering end-to-end web experiences with a performance-first mindset. On the frontend, my core stack is React + TypeScript + Vite, with Tailwind CSS, Chakra UI, and shadcn/ui, and I build hybrid mobile apps with Capacitor.js.
On the backend, I work with PHP + MySQL and Node.js + Express + MongoDB, including real-time systems with WebRTC and Socket.IO. I also enjoy building interactive maps and browser-first features, often pushing for measurable results—like rebuilding a WordPress site to boost PageSpeed Insights from 60 to 100.
As a Freelance Web Developer, I ship custom WordPress and Shopify (Liquid) solutions, and I’m known for strong self-directed learning and reverse-engineering skills. From offline-capable apps with IndexedDB to REST APIs with role-based access control, I love turning complex requirements into reliable, user-friendly products.
