Hi, I'm

Alejandro Quiroz

Full-Stack Developer building fast, accessible web experiences.

Specializing in React, Next.js, and TypeScript. Based in Medellín Colombia, working globally.

About me

I've spent over a decade turning business problems into software: ERPs for security and real-estate companies, personal finance mobile apps, admin platforms, and everything in between. Today I'm a Frontend Tech Lead at Endava for Lululemon Athletica, leading a 6-person team building high-traffic e-commerce with Next.js and Node.js every single day.

My path went bottom-up: vanilla PHP and raw SQL in 2013, my own ORM because no existing one fit, and from there to Symfony, React, React Native, and Next.js. That foundation gave me something you don't get by starting with a framework: understanding what happens underneath. Today I amplify that foundation with AI: GitHub Copilot in my daily work, and on personal projects I direct AI agents (Claude Code) through my own system of verifiable phases — I design the process that makes AI build well.

When I'm not coding, I'm working out or in front of a video game.
