Moritz. I build complete data and AI systems, end to end, on infrastructure you own.
Independent senior engineer and architect, based in the EU. I take a system from nothing to running in production: the infrastructure, the data, the AI and the app. Open source where it counts, hosted in the EU, and yours to keep.
How we can work together
Architecture and code review
1 to 2 weeks, fixed price
I read your code, talk to your team and write a report with a decision tree of options and a clear recommendation. Useful when you are not sure the current direction is right, or before committing to a big build.
Build
6 to 12 weeks, scoped, fixed-price option
We agree the deliverable up front; I build it end to end and hand it over with documentation and tests. Typical builds: AI search over your own records, a data pipeline or lakehouse, a paid product taken to production, an internal platform on EU infrastructure.
Fractional tech lead
2 to 3 days a week, 3-month minimum
Ongoing technical leadership without hiring a full-time lead: architecture, code review, mentoring and unblocking hard problems.
Pricing on request.
Selected work
Client work
AI system for a national governmentClient work, under NDA
Reads through large volumes of public records and surfaces the signals worth paying attention to. I built all of it: the data side, the AI, the app and the EU-hosted infrastructure it runs on.
Energy-simulation SaaSClient work, under NDA
A paid, multi-tenant product with accounts, billing and usage limits, and a simulation engine doing the actual maths behind it. Built end to end, on my own.
Products I build and run
Grid-access intelligence and scenario reports for Italy and Greece.
monopigiPython SDK on GitHub
One API for Greek government data: decisions, procurement notices and energy permits from fragmented public portals, normalised into a single queryable REST API.
ForgitryIn development, not public yet
An EU-hosted git forge for organisations that need EU data residency and no hyperscaler dependency.
Open source
Spec-driven project management where people and AI agents work from the same markdown files in git. CLI, MCP server and VS Code extension.
A typed configuration language in Rust. Every document reduces to one canonical, content-hashed value and imports are lockfile-verified, so config cannot drift silently.
A modern EUR-Lex parser for Python: async, typed, with a CLI and SPARQL support. On PyPI.
Side projects, iOS apps: Nandemaguro (tuner), Me-tro-no-my (metronome), Mealchemy (meal planning).
How I think about it
Code got cheap. Judgement, quality and team coordination got harder, and they matter more. Roles are shifting and the way teams collaborate is being redesigned. I help with the practical side: modern workflows and tooling, Lean development, and people and AI working together without losing the plot.
Contact
If you are building something with real complexity and need sharp engineering or architecture, I would like to hear about it. It does not have to be fully formed; a rough sketch or "I'm stuck on X" is enough.
