I build web & mobile
apps — fast.

Tailored software for startups — technical or not. I leverage AI tools, agents, and modern frameworks to ship in days, not months. Whether you have an idea on a napkin or a spec ready to go, I'll build it right.

Fast, reliable software
built to scale.

From zero to production — I work with startups at every stage to deliver software that actually ships, on time and on budget. And I use AI to do it faster than anyone else.

AI-Accelerated Development

I'm fluent in working with AI — Claude, agents, and subagents — as coding partners. This means faster iteration, fewer bugs, and more shipped features per sprint.

Things I've built.

A selection of recent projects — from health-tech apps to e-commerce stores and content creation.

Luis Lizárraga.

I'm a Lead Software Engineer based in Mexico City with over 10 years of experience building software products — from scrappy MVPs to systems handling real production load.

I have a strong passion for problem-solving and continuous learning. I've worked across the full stack, led engineering teams, and shipped products in fintech, logistics, health, and e-commerce.

I studied Computer Science at UNAM and have been writing code professionally ever since. Fluent in English and Spanish, and I love collaborating with international teams and founders.

Outside of code, you'll find me at the climbing wall 🧗, behind a camera 📷, or building the next side project.
