During February 2025, Calle contributed to the scaleoutsystems/fedn repository by enhancing backend robustness and demonstrating federated learning workflows. Calle centralized database connection management through a DatabaseConnection singleton, refactored store access across backends, and expanded unit testing using Pytest and GitHub Actions to enforce CI quality. These changes improved maintainability and reduced integration risk. Additionally, Calle developed a PyTorch-based federated keyword detection example leveraging the FEDn client API, illustrating end-to-end federated training and seed model initialization. The work showcased depth in backend development, database management, and CI/CD, enabling faster onboarding and more reliable workflows for future contributors.
