About
I'm an AI Agent Trainer and Software Engineer: an engineer who studied people. I help engineering, marketing and leadership teams get more done with AI agents, with the people they already have. I work in English or German, on site, remote or hybrid.
My background is unusual for an engineer. I studied psychology (BSc) and management (MA), with three scholarships along the way, so I treat AI adoption as a people problem as much as a software one. An agent only scales a team's work once people trust it and change how they work with it.
Before this, I spent six years as Co-Founder & CTO of the marketing agency The Happy Beavers (2018 to 2024). The automation I built there cut manual work by 80% and let an 11-person core team run more than 150 freelancers. Working beside marketers showed me where automation pays off and where people still make the call.
Today I offer three services:
- Training: engineering, marketing and leadership teams learn to hand their own work to AI agents (for engineers: Claude Code, Cursor, Copilot, Codex and MCP servers)
- Implementation consulting: a review of how a department works and a plan for where AI agents add output, in any department
- Development: agent systems and custom software in Elixir/Phoenix and Python that take repeat work off a team
Teams book my training directly or through L&D providers, and I build every programme around the team's own work.
Products I built and run myself:
- Tymeslot - an open-source scheduling app you host yourself, with live calendar sync and booking widgets
- Transvexis - multilingual translation platform serving clients in 39+ languages
- In A Nutshell - ask questions about long YouTube videos and get answers with timestamps
My articles draw on the same work, from what I see in training rooms to the systems I build and run myself.

What clients said about the training
From engineering teams I trained to work with AI agents.
I worked closely with Luka as the topic sponsor for a workshop on integrating AI meaningfully into everyday development work.
He took the time to understand our participants' needs and adapted his approach to the tools and working environments available.
Participant feedback reinforced my own positive experience, with especially strong recognition of his subject expertise and the balance between theory and practice.
I wholeheartedly recommend Luka as a trainer to any team looking to build practical AI skills.
We had a Cursor AI training with Luka. He is a highly competent trainer who answered all our questions thoroughly and adapted the course to our needs and preferences. I highly recommend working with him!

Claude's text watermark: who can detect it, and can you remove it?
13 August 2026
Claude now watermarks everything it writes. I read Anthropic's write-up, the EU law behind it and the research to find out who can detect the mark and what removes it.
Do LLMs write better Elixir than Python?

A Tencent benchmark ranked Elixir first for LLM code generation. As an Elixir developer, I checked the data and found the ranking overstated and the structural advantages real.
