Worked on the is-a-dev/register repository to deliver a robust domain configuration workflow for the redblog.is-a.dev subdomain. Focused on improving DNS management and deployment reliability by adding new Vercel domain configuration files and removing outdated TXT deployment records. Leveraged skills in configuration management, DevOps, and domain management, primarily using JSON for configuration updates. The changes streamlined the deployment process, reduced manual intervention, and enhanced traceability through clear repository hygiene. By enabling proper DNS verification and reducing configuration drift, the work improved hosting stability and minimized future maintenance overhead, ensuring a more reliable and manageable deployment environment for the project.
