About

I am an engineer for embedded and networked systems. I wrote firmware for MicroBlaze and STM32, built a C++ hardware and OS abstraction library, led a wireless access system from its gateway (Yocto, Mender OTA) to a production tester in Go, and did cloud DevOps on AWS. I also worked on RF and measurement, from UWB localisation to a 5.8 GHz network analyser.

That is where my standard for AI comes from: results must be checkable. So I build SIEGEL, a framework in which AI agents in fixed roles develop software. Requirements are frozen first, then tests, code, a QA report and docs follow, one commit per step, and a human signs off.

SIEGEL

Shown on request

A software company in a box

SIEGEL is my framework for verifiable AI software delivery. It runs a full product team of AI roles in a fixed chain, from CEO and product visionary through architect, designer and security engineer to QA engineers, developers and technical writer. Each role hands its work on to the next; where the work splits, sub-agents run in parallel. Gates sit between the steps, every step is a commit, hooks keep each role to its own files, and at the end a human sets the seal. The engine is written in Go and runs on tokens, from local or hosted models. Licensed Apache-2.0.

Why it matters: AI writes code fast. SIEGEL makes it checkable: every step is a commit you can read, and nothing ships without a human sign-off.

AI Software Engineering BootCamp

Digitale Leute School

  • AI Software Engineering Foundations
  • Product Skills for Engineers
  • Software Engineering with AI
  • Agentic AI Engineering

Retrieval-augmented generation (RAG), vector databases, agent workflows with sub-agents, and a chatbot built on an n8n webhook.

Capstone MVP: a local assistant for owner-run car workshops, designed to record a diagnosis in under 60 seconds so that workshop know-how stays in the shop. Built spec-first with SIEGEL; version 1.0 sealed for demonstration, the field test is still open.
