PROFILE
Cleisson Barbosa
Cleisson Zanfranceschi developed a containerized multi-service backend for the zanfranceschi/rinha-de-backend-2025 repository, integrating Nginx, two Lua backend instances, and Redis using Docker Compose. He established robust networking, resource limits, and load distribution to ensure scalable and consistent deployments. Cleisson upgraded backend images, cleaned obsolete logs, and resolved a port allocation bug in the Lua service, improving deployment reliability. He tuned memory and timeout settings for better performance under load and documented the architecture and setup in Markdown to streamline onboarding. His work demonstrated depth in backend development, containerization, and system administration, resulting in a maintainable and reproducible infrastructure.

Aug 1, 2025August 2025 monthly summary: Delivered a containerized multi-service backend (Nginx, two Lua instances, Redis) via Docker Compose with proper networking, resource limits, and traffic distribution, enabling consistent environments and scalable deployments. Upgraded app1/app2 backend images and cleaned obsolete logs/artifacts to reduce repo noise and streamline builds. Fixed a port allocation bug in the Lua backend to ensure reliable deployments. Tuned resource limits and performance (service and Redis memory, timeouts, keepalive) to improve stability under load. Added comprehensive documentation (README and architecture overview) to accelerate onboarding and align teams on design choices, including Lean 4 context. Performed cleanup and rollback of partial results to guarantee accurate test outcomes and reproducible evaluations.
