-   Mastery of Go paradigms including interfaces and generics to build modular, maintainable systems
-   Mandatory use of context for deadline management, timeouts, and structured cancellation
-   Experience with continuous deployment using GitHub Actions, Docker containers, and cloud infrastructure (AWS ECS, EC2, or equivalents)

-   Proficiency with Git, CI/CD pipelines, automated testing, infrastructure monitoring, and observability practices
