In August 2025, gldmelo developed a Payment Intermediation System for the zanfranceschi/rinha-de-backend-2025 repository, enabling seamless end-to-end payment flows for the Rinha backend competition. Leveraging .NET Minimal API for backend logic, PostgreSQL for data persistence, and Redis for caching, gldmelo orchestrated the system using Docker Compose and optimized PostgreSQL for improved reliability and throughput. The solution incorporated Nginx for routing and deployment, establishing a scalable architecture that supports onboarding new participants. While the work focused on a single feature, it demonstrated depth in backend development, infrastructure automation, and performance tuning, laying a robust foundation for future system expansion.
