Worked on the Deltares/fews-web-oc repository, delivering features and documentation that improved security, deployment reliability, and CI/CD workflows over seven months. Focused on backend development and DevOps, implemented Tomcat-based authentication, security hardening, and detailed deployment guides to reduce onboarding time and configuration errors. Enhanced CI/CD pipelines using GitHub Actions and TeamCity, integrating Playwright for end-to-end testing and automating test reporting. Used TypeScript, YAML, and Bash to manage configuration and automate processes. Addressed maintenance needs by introducing a maintenance mode feature and restoring test deployments, ensuring safe updates and consistent deployment governance across environments while maintaining clear, version-controlled documentation.
March 2026: Deltares/fews-web-oc focused on safe maintenance and CI/CD reliability. Delivered a maintenance mode feature for Durban and restored test deployments in CI/CD to ensure ongoing deployment capabilities while safeguarding user experience during maintenance windows.

November 2025: Updated deployment documentation for Delft-FEWS Web OC on Tomcat to clarify the use of ROOT and weboc distributions and provide substitution guidance to use weboc when appropriate. This reduces deployment ambiguity, accelerates onboarding, and lowers support overhead. No major bugs fixed in this period. Technologies demonstrated include Tomcat deployment concepts, distribution compatibility (ROOT vs weboc), and documentation best practices.
