Case Study

Architecture, delivery, and team leadership at scale.

Scaling Guatemala.com's platform to 5M+ monthly users

01The challenge

A multi-brand media network running on legacy monolithic WordPress, under heavy and spiky Latin American traffic — with ad revenue directly tied to speed and uptime.

02What I did

Led the backend re-architecture to headless WordPress + NestJS APIs on auto-scaling AWS, with Next.js frontends consuming them. Owned ad systems and performance, planned the migration path, and mentored the team while introducing AI-assisted engineering workflows.

03The outcome

A modern platform serving 5M+ monthly users, faster pages that protect ad revenue, and a stack a fully remote team ships on with confidence.
