Developed a custom domain configuration feature for GitHub Pages within the is-a-dev/register repository, focusing on scalable and repeatable domain provisioning. The work centered on creating a new JSON configuration file that defines both the domain owner and CNAME mapping, streamlining the process of associating custom domains with GitHub Pages sites. Leveraging skills in configuration management and web development, the implementation emphasized deployment readiness and traceability by establishing clear commit history. No major bugs were addressed during this period, as efforts were concentrated on feature delivery and laying the foundation for multi-repository domain management using structured JSON data.
