I am an independent engineer in Germany. I work alone, across the whole stack: training open models, running them locally, breaking my own software before someone else does, and building the agent systems that tie it together.
I started with Roblox scripting, writing game logic for other developers. It was a good first job. Thousands of people used what I wrote, they had no interest in how clever it was, and anything broken came straight back to me. That loop — ship, get hit, fix — is still how I work.
From there the work moved down the stack. Custom interfaces and in-game economies, then a game mod I rebuilt the interface layer for, then local inference on llama.cpp with my own model and provider configuration, then security: a red-team environment for my own services, and a written analysis of a real malware incident I had to contain.
Today most of my time goes into Prisma, a small open-source organisation I run that trains open models, and into a cybersecurity agent and the harness it runs in. Both will be released open source.
What I care about is the unglamorous part: does the system still behave when the inputs are hostile, the network is bad, and nobody is watching. Most demos never answer that question. It is the only one that decides whether something is real.
