The person
behind the code

I'm a PHP Backend Developer and Technical Lead based in Mexicali, México, with 13+ years of hands-on experience architecting, building, and scaling production web applications — including billing platforms that process millions of mobile payment transactions per month across LATAM.

At Gameloft, I led backend development for carrier billing and subscription platforms serving 10+ regional partners across Mexico, Central America, and South America. I designed RESTful and SOAP API integrations with mobile operators like Telcel MX and Claro, engineered a UUID-based PII anonymization system adopted company-wide, and was selected as one of two studio representatives for a global on-site in Bucharest to influence architecture decisions.

I've also led and mentored teams: defining technical scope, running code reviews, and training 5 cohorts of university students — several of whom I hired and later saw promoted to senior roles.

My surname — Buzo — means diver in Spanish. I like to think it captures something true: I go deep into problems, stay focused under pressure, and surface with something worth keeping.
