PROFILE
Tarcísio Zotelli Ferraz
During two months of focused engineering, Tar Ferraz modernized deployment and backend infrastructure for zanfranceschi/rinha-de-backend-2025, introducing HAProxy-based load balancing and optimizing Docker Compose configurations to improve deployment speed and reliability. He consolidated resource management settings, enhanced benchmarking performance, and reduced environmental noise by cleaning up logs and artifacts. In smartcontractkit/chainlink, Tar implemented robust log filter matching in the Fake EVM, adding explicit error handling and comprehensive test coverage to ensure correctness and resilience. His work leveraged Go, Docker, and HAProxy, demonstrating depth in backend development, system configuration, and testing, with a clear emphasis on reliability and maintainability.
