PROFILE

João Otávio Biondo

João Biondo established the backend foundation for the zanfranceschi/rinha-de-backend-2025 repository, focusing on scalable architecture and performance optimization. He implemented the core application using Elixir, integrating Bandit for HTTP handling and Redis for data storage. His technical approach included configuring Unix Domain Sockets and connection pooling to reduce latency and improve throughput. João also set up HAProxy for load balancing and Broadway for asynchronous job processing, ensuring the system could handle future growth. The work resulted in a robust, observable backend platform that supports rapid feature development and simplifies capacity planning, demonstrating depth in backend development and system architecture.
