👋 Hi, my name's Kristjan.

💫 Professionally, I'm a DevOps Engineer at a telco company where I focus on Kubernetes and end-to-end deployment automation (deployment of whole platforms in air-gapped environments).

Here's a high level overview of tools, languages, frameworks and platforms I'm comfortable with.

Operating Systems and daily drivers:

• Ubuntu cloud -- most comfortable one
• Fedora, RHEL, RHCOS -- when working with Openshift
• Alpine -- base container image
• Arch -- old personal laptop, efficient use of hardware
• Windows + WSL2 -- current daily driver; good for programming (Linux shell) without losing Windows features (company compliance...)

Cloud platforms:

• OpenStack -- tenant admin (networks, storage, routers, ...)
• vSphere -- deploying VMs
• AWS -- deploying VMs
• OCI -- deploying VMs, some networking

Container platforms:

• Kubernetes -- deployment from scratch; favorite distro is k3s, using Kubeadm and Rancher for work projects
• OpenShift 4 -- deployment from scratch (UPI), had to leran it for a work project, prefer vanilla Kubernetes

Tools:

• Helm -- go-to tool for deploying apps on k8s
• Terraform -- go-to tool for interacting with any cloud
• Ansible -- go-to tool for provisioning (Linux) servers

Programming languages (profficient - daily usage):

• Golang -- backend services, REST APIs, cli tools
• bash -- automation, scripting
• Python -- automation when bash gets too verbose; string manipulation with Jinja2; data manipulation with Pandas; general purpose get-stuff-done-quickly language

Other programming languages (pp - personal projects, uni - university, pro - professional development):

• Rust -- pp, staying in programming shape
• Kotlin -- pp, Android Studio app
• Elixir -- pp, web scraping
• Haskell -- pp. Advent of Code
• C++ -- uni, pp, OpenCV, QT
• Java -- uni
• C -- pro, fixing bugs on old telco apps
• JavaScript -- I like to use TypeScript wherever possible
  • Vue framework -- pro, internal dashboards
  • React framework -- pp
  • Electron -- pp
