Koen Gremmelprez
Koen contributed to the CitizenLabDotCo/citizenlab repository by delivering features and improvements across backend, frontend, and DevOps domains. He enhanced HTML-to-PDF reliability by correcting Gotenberg client configuration in Ruby, streamlined backend initialization for the feed component, and refactored AI provider configuration retrieval for maintainability. On the frontend, Koen implemented an in-app transcription feature with automated CI/CD using CircleCI and Node, and improved deployment reliability with remote file previews. He also simplified local development by cleaning up Docker Compose configurations. Throughout, Koen applied skills in Ruby on Rails, JavaScript, and containerization, focusing on maintainable, review-friendly code and robust workflows.
