PROFILE
Michał Dąbrowski
Worked on the allegro/hermes repository, delivering backend features and infrastructure improvements over four months. Focused on stabilizing cross-platform builds and enhancing CI/CD reliability using Docker, Gradle, and GitHub Actions. Introduced structured logging with Java and logging frameworks to improve observability, upgraded dependencies for better performance and security, and enhanced test automation with integration testing and retry logic. Improved code quality by streamlining interfaces and refining error handling, while also enabling more configurable Kafka producer behavior. Documented feature deprecations and migration paths, ensuring maintainability. These efforts resulted in more reliable deployments, faster feedback loops, and a cleaner, more resilient codebase.
