Theatrical Booking

This is a booking application for a large entertainment enterprise. This application needed to be migrated from EC2s to Kubernetes. It had several microservices as well.

I migrated the application to Kubernetes, set up monitoring and alerting, and deployed all the CI/CD pipelines for developers to promote the code through the environments.

Container Pipeline

I created a Docker container CI pipeline, which allows for the hierarchical build of dependent containers on a Git push event or a schedule. This allows for the "latest" containers to always be up-to-date and pass the vulnerability audits.
