Worked on the is-a-dev/register repository to enhance and restore the domain verification workflow, focusing on backend development and configuration management. Introduced a configuration-driven approach using JSON files to automate domain verification and DNS record management, which streamlined the onboarding process for new domains. Addressed a critical issue by updating the TXT record after an accidental deletion, ensuring that verification functionality was promptly restored. This work reduced manual troubleshooting and deployment delays, improving reliability for domain management tasks. The technical solutions leveraged skills in backend systems and domain management, with an emphasis on maintainability and automation through structured configuration files.
