Worked on the 2i2c-org/infrastructure repository to enhance access control for data science workloads, specifically enabling the BIDS URAP group to access the jupyter-health cluster. Addressed this requirement through a targeted configuration management update, implementing a single-line change in YAML to adjust group permissions. The work focused on DevOps practices, ensuring that the modification was clearly documented in version control for transparency and future maintainability. No additional features or bug fixes were introduced during this period, reflecting a focused and incremental approach to infrastructure management. The contribution demonstrates attention to precise configuration and secure access provisioning using YAML.
