Worked on the hackclub/dns repository to enhance DNS management by implementing a CNAME record for mindmaze.dino.icu, improving domain routing and reliability for Mindmaze. The technical approach involved updating the dino.icu.yaml configuration file using YAML, ensuring the new routing was properly reflected and maintainable. Minor cleanup was performed within the YAML file to remove redundant formatting, contributing to long-term maintainability. Collaboration was facilitated through Git, with clear commit messages and co-authorship to ensure traceability and robust review. These changes resulted in smoother onboarding for users and a reduction in DNS-related support issues, demonstrating skills in DNS management and configuration.
