Developed a config-driven feature for the is-a-dev/register repository that enables per-user pages with custom domain support, streamlining onboarding and personalized branding. The solution centers on a JSON-based configuration system, allowing each user to define their page content and domain mapping through individual config files. By updating the CNAME record to point directly to a user’s GitHub Pages site, the approach reduces manual setup and simplifies deployment. Leveraging skills in configuration management and web development, the work improved maintainability and scalability for user pages, laying a foundation for future enhancements while focusing on automation and centralized configuration using JSON.
