Worked on the gdsfactory/gdsfactory repository to deliver a targeted documentation update supporting the migration from the GlobalFoundries 180nm CMOS PDK to the new GlobalFoundries 180nm MCU PDK. Focused on clarifying migration steps and updating resource references, the work was implemented using Markdown and managed through version control systems. By providing a precise, traceable commit, the update improved onboarding for developers and reduced ambiguity during the PDK transition. The documentation changes preserved repository stability and ensured that users had access to accurate, up-to-date information, reflecting a methodical approach to maintaining codebase integrity and supporting developer experience through clear documentation.
