Developed a domain configuration management feature for the is-a-dev/register repository, focusing on automating domain ownership verification and DNS A record provisioning. Leveraged JSON for data serialization to define owner details and required DNS records, resulting in reproducible and automated domain onboarding workflows. The approach reduced manual configuration steps and minimized potential errors during deployment. Utilized configuration management and DevOps practices, integrating Git version control to ensure traceability of changes. No major bugs were reported or fixed during this period. The work demonstrated practical application of JSON-based infrastructure configuration, domain verification processes, and deployment automation within a collaborative development environment.
