Project History
Release Management Automation
This application was part of an organizational initiative to allow continuous deployment of all applications to production without manual validation. Following the organizational standards, the application should fulfill specific criteria before production deployment, such as successful build, unit testing with at least 80% code coverage, successful integration testing, static code assessment, and open-source vulnerability assessment.
This application is an orchestration layer to integrate with all CI/CD tools in the organization to validate the outcome of required checks specified above and make a go or no-go decision for the production deployment. A web interface was implemented to review results and schedule releases.
As a tech lead on this project, I have been deeply involved in design, implementation, and deployment. This project was implemented in Go and AngularJS and deployed on Kubernetes clusters in AWS. Given the criticality of the project, we have put a high availability system with backup and disaster recovery and monitoring systems in place.
