Work Experience

DevOps Engineer

2012 - PRESENT
strogo pro
  • Created an OpenVPN setup where each client would have his own personal IP and iptables rule; used Bash script for adding new users which would send a password-protected archive to the client along with "How to Configure VPN" instructions. The passwords would be sent through a different channel.
  • Deployed GitLab inside Docker (with volumes for permanent storage); created web hooks that would trigger Jenkins jobs on "git push."
  • Created an environment for easy Docker deployments—SQL database with hostnames, service names, versions, container parameters, and more which would be used in a Jenkins job.
  • Wrote a Bash script for Check_MK which would scan for Docker containers in a "Restarting" mode and report to Slack with the hostname, service name, and logs for that container.
  • Created an environment for multiple customers on a server utilizing LXC with a NGINX proxy in front of them.

Experience

Badazoom

I was part of the Badazoom team since the beginning which meant that I worked on every part of the infrastructure. This included configuring instances in AWS and setting up different environments, VPN and more to automating the deployment of Docker containers through Jenkins and Git hooks and to set up the monitoring.

OSM

http://www.osm.rs/
I created an infrastructure for team collaboration: a VPN, GitLab (running in Docker container with mounted volumes), Jenkins, Slack with integrations, and a couple of Bash scripts.

I also set up a server for showcasing the project—one server with multiple LXC containers all behind a web proxy.
