Started with Minecraft plugins, arrived at enterprise software and AI agents. Never stopped building in between.

About
The person behind the code
I'm 20 and based in Munich. It started in 2016 with Minecraft plugins, because a game should do something it could not do on its own — on the side at first, and seriously and regularly for a good five years now. That question turned into a career: through Python and server administration, through client work on the web, all the way to SAP development in an enterprise context.
Today I build on two fronts. Enterprise by day: ABAP, Fiori, ERP processes. Software that runs at the core of a company and forgives no mistakes. Alongside that, Myrodex, my own startup, where we build a management platform for esports organisations, including our own AI agent with tool access to the platform data.
What I like about the work is the moment a system stops being complicated, when the right abstraction is found and the rest follows by itself. That is why I care about architecture, about tests, and about someone else still understanding the code a year from now.
Away from the screen I train a lot: competitive endurance sport and regular strength work at the gym. Both for the same reason as programming. It is about working patiently on something that only becomes visible after months.

How this worksUpdated this minute
A Node script reads the JSONL logs of my local Claude Code sessions, sums the token fields per model and per day, and writes an anonymised snapshot into the repo. The site loads it through an API route. Project names and conversation content never leave my machine.
