PROFILE

Joao Bittencourt

João Bittencourt worked on backend modernization for the zanfranceschi/rinha-de-backend-2025 repository, focusing on migrating the backend from a MySQL-based stack to a PHP-Redis architecture orchestrated with Docker and Nginx. He implemented a Docker-based deployment pipeline, updated PHP-MySQL configurations to use newer images, and removed unnecessary database settings to streamline maintenance. João also optimized the Docker Compose setup for the PHP backend, cleaning up test environments and tuning resource usage to improve reliability and speed. His work included updating documentation to clarify technologies and setup steps, demonstrating depth in backend development, containerization, and environment stabilization using PHP, Redis, and Docker.
