WebSocket Proxy for Angular Front End Written in Go

I designed, implemented, and maintained a WebSocket proxy that was hosted in Kubernetes, and provided the secure gateway to services required of our Angular based account management tool.

The proxy:
1) managed logins via Firebase
2) Created, validated and expired sessions for each logged-in user
3) Provided a consistent JSON based request/response structure to support the various services that were interacted with to provide a rich experience in the UI.
4) I created, and made accessible, DB functions to improve performance on queries the UI needed to make to provide summary information to the users.

I continued to provide additional functionality and maintenance after the initial release to production.

Infrastructure as Code Targeting Terraform

Reverse engineered existing AWS resources, including EKS, and networking infrastructure, into Terraform for portability and consistency to allow environment reproduction in different accounts as needed. Added support for simplified deployments to Kubernetes, using Kubernetes controllers supporting external DNS, certificate management, and ingresses. Provided guidance on adding additional components via Terraform or Kubernetes controllers to support developers' ease of use. Provided documented set up and instructions to educate developers on the process being provided.
