Renzo Mayer

About

Software engineer and tech lead who kept drifting toward the place where data, growth and product meet.

I am a software developer with an enthusiasm and focus on web applications. I care about building immersive, fast, scalable interfaces through carefully crafted code and user-centric design — and about the systems around them: continuous integration, continuous improvement, continuous delivery.

For five years I owned end-to-end delivery of more than 200 revenue-critical web properties and led a distributed squad across Uruguay and Costa Rica. That work was equal parts frontend craft, infrastructure as code and relentless automation, because there is no other way to operate that many sites without losing your mind.

Today I work with a marketing team on acquisition, brand awareness, content distribution and analytics — growth supported by technology and AI. In parallel I keep pushing on the data side: foundations you can actually ask questions of, with agents evaluated against real outcomes.
