Building beyond the demo
What happens around an AI agent matters as much as its answer.
Architecture & engineering
AI Engineer · Based in Germany
Hi, I’m Laurenz. I build things with AI.
I’m an AI Engineer focused on agentic AI, LLM applications and AI architecture. I build with Python and LangGraph, with a background in machine learning, computer vision and reinforcement learning.
// a few things I’ve worked on
From a question to a project.
What keeps me curious.
MODULE_01
Agentic AI & LLM systems
Connecting agents with tools, durable state and clear application boundaries.
- LangGraph
- LangChain
- Tool use
MODULE_02
AI engineering & architecture
Building the APIs, data contracts and operational controls around a model.
- Python
- FastAPI
- PostgreSQL
- Docker
MODULE_03
Machine learning, vision & RL
How can a system learn from what it sees — and use it to act?
- PyTorch
- Feature learning
- PPO
// along the way
How I got here.
Applied computer science in Bochum, then data science and AI engineering. Still curious. Still building.
