Refactoring the CI/CD Process: Removing custom scripts and replacing them with industry-standard tools for better maintainability and error reduction.

Introducing NX: We used NX to efficiently handle the monorepo setup, ensuring only the modified parts of the project were rebuilt.

Deploying with Argo CD: This reduced deployment errors and streamlined the process.

Minimizing Build Steps: By eliminating redundant steps, we reduced release time from over 30 minutes to around 5-6 minutes.

Consolidated Environments: Reduced from six separate Kubernetes clusters to two—one for development/testing and one for production.

Namespace Segregation: Applications were virtually separated within Kubernetes namespaces, avoiding the need for multiple physical clusters.

Terraform Automation: Used Terraform for infrastructure management, making future deployments faster and more reliable.

Monthly infrastructure costs decreased from around £2,500 to £3-400 for development and testing.

After adding production, total costs were around £7-800 per month—a third of the original costs.

The client saved thousands of pounds annually while maintaining robust infrastructure capabilities.

Immediate Testing and Bug Fixes: We prioritized identifying and fixing critical bugs to prepare the system for production.

Efficient Release Cycles: The optimized CI/CD pipeline enabled quicker iterations and better testing coverage.
