AI Systems Architect · Founder/CTO · Mathematician
I build the system around the model: architecture, backend, data, evaluation, observability, and cost control for AI products that have to hold up in production.
M.Sc. Mathematics (TU Berlin), 8+ years in software engineering and data science, CTO and co-founder of a stealth AI startup.
- Architecture for AI products that outgrow the prototype
- LLM orchestration, agent workflows, and context design
- Python and FastAPI backends, Postgres, async workers
- Evaluation, observability, reliability, and cost control
- Memory, state, and knowledge infrastructure
A FastAPI starting point for LLM services you can run and debug in production, with route/service/schema separation, provider abstraction, structured JSON logging, request IDs, tests, Docker, and CI.
Use it to find the weak points of an AI system before launch. It covers architecture, LLM workflows, observability, evals, RAG and context design, cost control, security, deployment, and reliability.
An authenticated remote MCP server that lets Claude, ChatGPT, and other AI apps read and write a single GitHub-backed knowledge vault. Scoped tool registry, token-based auth, per-member commit attribution, and a hard single-repository boundary.
The design and reasoning: Beyond Chat History: Building an AI-Native Second Brain with Obsidian, GitHub, and MCP.
Architecture notes and a review template on workflow orchestration, semantic observability, and system boundaries in production AI systems.
I write about how modern software and AI systems work and how to make good engineering decisions about them: mechanisms, trade-offs, and what breaks in practice. Articles are on my blog.
I also teach AI software engineering to people who want to turn an idea into a working product.
I take on selected freelance projects in AI and software architecture, focused on the DACH region and the rest of Europe. Most start with a fixed-scope reliability review of an existing AI product.
