Eddie Ndulo developed a scalable, production-ready backend for the zanfranceschi/rinha-de-backend-2025 repository, focusing on high availability and efficient deployment. He architected a multi-instance Node.js Fastify backend with Nginx load balancing and PostgreSQL integration, enabling horizontal scaling and robust data management. Eddie enhanced deployment workflows by introducing pre-built Docker images, explicit resource limits, and optimized port exposure, which improved startup times and resource utilization. He also strengthened error handling and integrated fallback payment processors to ensure reliability during incidents. His work demonstrated depth in backend development, containerization, and system architecture, laying a solid foundation for resilient, maintainable production operations.
