This project structure allows engineers to:

1. Work on specific environments they are allowed to.
2. Add/Remove modules as they need in order to build their applications within their environments.
3. Deploy specific applications/modules (e.g.: networking, addons, argocd-app-1) within their specific environments.

Each envs folder (dev, prod, etc) is associated with a specific Terraform workspace.

• rating-ns deployment
• HPA enabled for deployment
• Grafana Dashboards and Panels showcased

• infinite-requests deployment deleted -> load testing source removed

• HPA terminating pods based on null CPU consumption

I believe the best place to work is the one where I can evolve and challenge myself in projects while collaborating with amazing people and working on platforms that improve people's lives on a daily basis.

Every time I go outside my comfort zone, I find myself traveling to unvisited corners of my mind, felling closely to untapped emotions, watching hidden desires become visible for the first time and I always come back to this:

The only constant throughout my life has been my desire to communicate and build.

I communicate by working on challenging projects, writing and condensing a decade worth of experience within my development blog, performing live music mixes, looking for outdoor activities and chess matches.

I build through software and infrastructure, system design, piano tunes, writing and sketching.
