About Me

Hi, I’m Juan Carlos (a.k.a. Jaxo), a Senior Fullstack Developer, Systems Architect, and IT Manager based in Querétaro, Mexico.

I design, build, and optimize complete software ecosystems — from backend architecture, databases and infrastructure, to full web applications, APIs, automations, and production systems used by thousands of real users.

I’ve spent more than 20 years creating tailored solutions for companies in Mexico and the U.S., reducing costs, improving processes, and bringing complex ideas to life with clean, reliable engineering.

If you need someone who can take a project from concept to production — end to end — you’re in the right place.
