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.
