UI VPN Client for Linux
https://github.com/gasilva-clgx/evpn1I developed this project using Electron and Node.js, testing it only on GNOME environments. This project is packed and distributed as an AppImage file, but unfortunately, I am no longer maintaining it.
Simple 3 Tier Demo
https://github.com/gasilva-clgx/3tier> the DevOps integrated with SDLC
> Infrastructure as code (Terraform);
> How to create and provision a Kubernetes cluster, virtual machines, and databases.
> Use Ansible to keep an environment configured, even when unintended changes are made.
> Kubernetes and CICD pipelines
> Networking security
> The most important of all: ALWAYS pay the technical debit; Examples of good documentation, secret management, and good communication
