Worked on DNS provisioning for the hackclub/dns repository, focusing on enabling seamless routing for the Sayhan subdomain. Implemented a CNAME record in YAML to direct traffic from the sayhan subdomain to sayhan.hackclub.app, ensuring accurate DNS resolution for new users or applications under the Sayhan identifier. This approach streamlined onboarding and improved reliability by reducing manual DNS configuration steps for new services. Leveraged DNS management skills and configuration-as-code practices to automate the process, enhancing maintainability and scalability. The work addressed business-oriented requirements for DNS routing, with all changes tracked and committed for transparency and future reference within the repository.
