About me

My name is Luis Carlos, though everyone calls me Lucho. I've been building web applications for over 4 years that solve real problems and feel great to use.

I've worked on projects where teams cut weeks of work down to days with the right tools, and where manual processes simply ceased to exist. That's what drives me: seeing the direct impact of what we build.

Working remotely from Rionegro, Antioquia 🇨🇴 as a Full Stack Developer at PrevalentWare, mainly with React, Next.js, and TypeScript. Outside of code, you'll find me at the gym, out riding my motorcycle, playing Fortnite, or diving into workflow orchestration with n8n.
