Freelance · Consulting & Architecture

Digitalisation, AI workflows and web architecture.

Digitalisation and AI for companies that need to ship.

Manual operations turn into clean digital workflows — and AI gets embedded exactly where it measurably pays off. Plus classic web projects, taken on freelance as architect and developer.

Focus areas

Three focus areas. Pick one — or combine them into a programme that fits your business.

Process digitalisation
Replace Excel workarounds, manual handovers and email ping-pong with clean internal tools. From the pain point through the solution sketch to production software.
  • Excel workarounds out, internal tool in
  • Hours saved per case, every case
  • One clean source of truth instead of three
AI workflows
Embed language models and agents where they measurably save time or open new product value — assistants, document pipelines, RAG, auto-triage.
  • Recurring tasks handled by an assistant
  • Knowledge in PDFs and wikis becomes ask-able, not just searchable
  • AI running in production, not stuck in a sandbox demo
Web architecture & development
Standard web projects as a freelance architect or full-stack engineer. From product idea to production, or embedded with your existing team.
  • A new product live — from empty repo to first user cohort
  • An architecture that still holds in three years
  • Technical leadership on demand, without locking in a senior salary

Depth and speed

Enterprise discipline meets startup speed. Clean audit trails where the process demands them — and "live in two weeks" when that is the metric that matters.

Enterprise depth

Years of enterprise experience inside large, regulated environments: complex domains, critical integrations, event-sourced systems with full traceability, long-lived codebases. Software built to the standard required when it has to be maintained for five years.

Startup speed · peopleeat

Founding architect of a food-tech platform — architecture calls under uncertainty, fast iterations, MVP to product. Shipping without painting the next step into a corner.

Currently capacity for 1 project from August 2026

Let’s talk about your project

Describe what you’re working on in a few sentences — the assistant asks a couple of focused questions, summarises the brief and sends it to me by email. You hear back from me, usually within 24 hours.

Across time zones

Used to working with distributed teams in Canada, the US and India. Early calls before breakfast or late calls after dinner are part of the package, not the exception.

Time-zone flexible

Calls when your team is actually working.

Working with teams in North America or India from a German vantage point means very early or very late slots. I am open to those and used to them.
