What I do

I am a freelance software developer and system administrator. I help startups with maintaining their projects and IT infrastructure.

Here are some examples of what I do:

  • Automate server deployment and configuration
  • Keep servers updated and secured
  • Find a way to scale your application and identify performance bottlenecks
  • Setup server monitoring
  • Setup periodic backups of your data
  • Develop custom scripts and programs

I'm able to create systematic solutions that work long-term with minimal maintenance. I'm always looking for ways to decrease technological debt you might have. I can implement automation of your most frequent tasks so you or your team don't waste time doing them over and over.


Here are some of the technologies I use:

  • Fedora, CentOS, RHEL, Debian, Ubuntu
  • systemd, SELinux, firewalld, NetworkManager
  • Kubernetes, Docker, Rancher
  • AWS, GCP
  • Ceph, NFS
  • Ansible, Terraform
  • nginx, HAProxy, uWSGI, gunicorn
  • Python, Flask
  • PostgreSQL, PgBouncer, MySQL
  • Redis
  • TimescaleDB, Grafana, Zabbix
  • Git
