ABOUT

I use technology to solve real problems.

I have been interested in IT for more than two decades and have worked professionally in the industry since 2011.

My interest started with home computers, electronics and hardware repair. Over time this expanded into operating systems, networks, services, servers, automation and creating my own solutions.

At work I value the ability to find the real root cause, understand the environment and take a solution through to completion. I work comfortably both independently and as part of a team.

Outside work I develop personal projects related to Home Assistant, automation, software and music.

This public portfolio intentionally presents my scope of experience without exposing client infrastructure details, operational data or internal procedures.
