Moritz. I build complete data and AI systems, end to end, on infrastructure you own.

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

• ampear

  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

• Zettelgeist

  Spec-driven project management where people and AI agents work from the same markdown files in git. CLI, MCP server and VS Code extension.

• Mangrove

  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.

• eurlxp

  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.

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.
