Gabriel Barroso

Worked on Go-based network capacity services handling millions of requests per hour and proposed a MySQL/Redis-driven approach to decouple last-mile carrier mapping from production deployments. Improved code quality, performance, and security, reducing last-mile production incidents by 30%.

Designed and built an event-driven backend system integrating POS and online ordering data at scale (2,000+ locations, 1M+ events daily). Reduced API latency by 40% and AWS infrastructure costs by 10% through horizontal scaling, batch processing scheduling, and optimized database reads/writes.

Built and maintained AWS-based card payment processing services, driving a 12% increase in opt-ins and a 20% reduction in opt-outs within one year. Developed an AWS Glue data pipeline integrated with a data mesh and automated AWS Lambda routines to prevent database partition bloat.

Built a web document management system with multi-role access, file versioning, review workflows, and automated email notifications. Centralized engineering planning workflows, improving workflow speed by 15% and eliminating file loss.

Earned a Bachelor of Science in Software Engineering at Pontifical Catholic University of Minas Gerais in Belo Horizonte, Brazil.
