Guilherme Barroso

I'm Guilherme, a Senior Full-Stack Engineer with 10+ years of experience in global and multicultural

teams building scalable, high-performance systems across Frontend (React, Next.js), Backend

(Node.js, NestJS), and Cloud Architecture (AWS, microservices, BFF, REST APIs). I've led initiatives

such as reducing API response times by ~98% through asynchronous system design, leading teams

of up to 14 engineers during major platform transitions, and migrating 20+ services across cloud

environments while maintaining performance and lowering operational costs.
