During April 2026, contributed to the flowr-analysis/flowr repository by developing a standardized development container setup tailored for TypeScript and Node.js projects. This work focused on containerization and DevOps practices, establishing a reusable base image and scaffolding to streamline onboarding and daily workflows for developers. The configuration enables consistent environments across teams, laying a foundation for future enhancements and additional tooling. The implementation was documented with clear commit references to support traceability and ongoing development. While the setup currently does not include R interpreter support, it provides a robust starting point for expanding language and tooling compatibility in future iterations.
