Case Study
How I approach scale — one real example.
Scaling Guatemala.com 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 re-architecture to headless WordPress + NestJS APIs + Next.js frontends on auto-scaling AWS. 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.

What you get when you hire me
Beyond the stack — how I actually add value.
End-to-end ownership
From architecture to production: I design it, build it, ship it, and operate it. You get outcomes, not tickets.
Team leadership
Years leading and mentoring remote engineering teams — clear async communication in English (C1) or Spanish.
Applied AI, for real
Agents and RAG shipped in production products and daily team workflows — not just demos.
