• Architected the configuration and safety logic for a cloud-managed DNS platform across 6 services, designing a fail-safe precedence model that guarantees a device’s network settings are never corrupted by an incomplete or ambiguous config.
• Built the device-side integration layer connecting two platforms (QNAP NAS appliances and Ubuntu hosts) to the platform, with automatic retry and rollback so a failed update can never leave a device without working DNS.
• Engineered GitHub Actions CI/CD pipelines automating build testing and Nexus artifact deployment, eliminating manual steps from the release process.
