Worked on the hackclub/dns repository to deliver a custom domain and CNAME configuration for Hackpad, enabling the service to operate under a self-hosted domain. Focused on DNS management and configuration management, the work involved updating CNAME records using YAML to align with evolving deployment requirements and hosting strategies. This approach improved accessibility, branding, and administrative control for Hackpad, while also ensuring consistent domain resolution across environments. The changes supported a smoother user experience by stabilizing domain mapping and reinforcing trust in the platform. The project demonstrated proficiency in infrastructure configuration and effective cross-team coordination within a short timeframe.
