Diego Perez Giordan

About Me

Self-taught programmer since age 12 and backend engineer based in Montevideo, Uruguay. After 3+ years as QA Engineer at Cencosud, I transitioned into Go backend development — building microservices for a multi-country e-commerce platform serving millions of users across Latin America.

In my own time I build games, tools, and systems — all in Rust. From Bevy ECS game projects inspired by retro MMORPGs to full-stack web apps with Axum. I'm also deeply invested in AI-augmented development, using LLMs daily to accelerate architecture design, code review, and delivery.

Passionate about retro MMORPGs, Linux, and Neovim. Advocate of compile-time safety, TDD, and clean architecture. I believe the best code is the code that the compiler already verified for you.
