Developed the initial portfolio site setup and hosting configuration for the is-a-dev/register repository, focusing on enabling public publishing through a JSON-driven user profile and DNS CNAME-based hosting. The work centered on adding a structured woongjin.json file to manage user data and configuring the necessary CNAME record to support static site deployment. Leveraging skills in configuration management and data formatting, the developer utilized JSON for data representation and version control to ensure traceability. This contribution established a reproducible baseline for portfolio hosting, streamlining onboarding for new users and laying the foundation for future automated hosting workflows without reported bugs.
