About

Hi, I'm Tomass.

I've spent 12+ years building systems that have to work in the real world: telecom networks, energy hardware, IoT fleets and the platforms underneath them. These days I also run a team of AI agents, and I help other teams do the same.

I'm a hands-on architect. I like turning messy operational domains into platforms that are simple to run, cheap enough to keep, and pleasant to work on. I've been the founding backend developer, the lead engineer, the technical lead for client teams of 20, and the person who rewrites the deploy pipeline on a Friday so nobody has to fear Mondays.

Lately the most interesting problem is AI. Not "add a chatbot", but putting AI to work on real engineering and operations: agents that own repositories, keep docs and conventions in sync, and MCP servers that let AI act on real systems with a human approving the changes.

Tomalaci Systems AB is my consultancy, based in Stockholm, Sweden and working with clients internationally. When you hire the company, you get me.
