Curriculum vitæ


I moved my focus to all things DevOps starting in February 2020 by learning Kubernetes the hard way. I was tasked with deploying a backend to Azure AKS, so I've written all YAML from scratch (well, almost, thanks Kompose) in a matter of two weeks.

I'm using Docker and its tools (docker-compose, Dockerfile) with orchestration (Kubernetes on AWS and Azure, but also Docker Swarm and MicroK8s), and CI/CD provided by TeamCity or Jenkins. I've used NGINX, Traefik or Ambassador as ingress controllers.

I prefer Ubuntu or CentOS environments under Proxmox, with Ansible doing all the heavy lifting. I've used Terraform on Azure. I'm utilizing SOPS for managing secrets.

I'm using either Git or Plastic SCM for VCS and GitOps, with YouTrack for keeping track of bugs and tasks.

I have basic knowledge of Python language, HTML/CSS, and PostgreSQL and MySQL administration.

My homelab is running on multiple nodes of Ubuntu machines, serving me all-dockerized Quake 3 Arena OSP dedicated server, Pi-hole, Nebula, Portainer, Unifi Controller, and Jenkins building this very website using Ivy, serving it with Caddy, and Traefik as reverse-proxy.

I'm currently dabbling more into learning Helm, Argo CD, Go, and sharpening my Ansible, Terraform, Bash, and Python knowledge.
