Senior DevOps & Systems Engineer
30 years in IT, 20 of them running production infrastructure at one company. I keep servers, clouds and services of small and mid-sized businesses healthy, secure and boring — in the best sense of the word.

About me
I started in IT when the job was still called “system administrator” — racking servers, crimping cables and writing the first shell scripts. Since then I have grown with the industry: virtualization, configuration management, containers, CI/CD, public clouds and observability.
For the last 20 years I have been responsible for the infrastructure of one company without interruption: availability, security, backups, monitoring, cost control and on-call troubleshooting. I know what breaks at 3 a.m. and how to make sure it doesn’t.
Now I work independently and help small teams that need a senior engineer, but not a full-time one: predictable monthly support, clear reports and fast reaction when something goes wrong.
- Clear written agreements: scope, hours, response time
- Monthly report: what was done, current risks, recommendations
- Documentation you own — no lock-in
- English & Ukrainian, Russian
