Joscha Henn contributed to the TUM-Dev/gocast repository over eight months, focusing on backend stability, developer experience, and feature delivery. He enhanced streaming reliability by refining error handling and stream version logic in Go, while also improving data integrity through input validation and XML parsing. His work included Docker-based local development optimizations, dependency upgrades, and robust testing infrastructure using Go modules and mocking frameworks. Joscha addressed security by sanitizing user input and strengthened deployment pipelines with containerization and code linting. His engineering approach balanced backend improvements with frontend data handling, resulting in a more stable, secure, and maintainable codebase.
