Developed and delivered a domain configuration management feature for the is-a-dev/register repository, introducing a JSON-based configuration file to manage domain ownership and DNS records for tekk.eu. This backend development work established a foundation for scalable, configuration-driven domain onboarding and centralized domain settings within the application. By modeling domain ownership and DNS details in JSON, the implementation enables in-app management and supports future automation of domain registration workflows. The approach emphasized commit-based traceability, with all changes clearly documented for maintainability. No major bugs were addressed during this period, with the focus remaining on backend logic and domain configuration processes.
