Developed a scalable portfolio hosting data model within the is-a-dev/register repository, focusing on enhancing data structure management for web and Flutter development workflows. The work involved designing and implementing a JSON-based schema to store portfolio hosting information, including repository links, owner details, and CNAME records. By evolving the schema from a single 'record' to a multi-record 'records' format, the solution now supports multiple hosting configurations, enabling greater flexibility for downstream services. All changes were tracked with clear commit traceability, ensuring maintainability and transparency. This approach provided a reusable, extensible data source for portfolio hosting and related web development needs.
