one framework
Config & DI, enterprise user management with SSO and RBAC, an AI assistant with MCP + skills, and multi-AI image generation — each importable on its own.
one model layer
Map Python classes to nodes and edges, version your schema as replayable scripts, then switch between Neo4j, FalkorDB, Memgraph, ArcadeDB and Apache AGE without rewriting a model.
voice control
"Alexa, switch to ZDF." TV, blinds and heating driven from
your own server, with its own OAuth2 IdP — credentials never
leave your network.
Capacity Planning
Manage team capacity, forecast utilization, handle absences and public holidays. Report project risks and cost forecasts.

Building software since 1987. By day, working as Senior Manager AI Solutions at Arvato Systems; after hours, the open source you see here.
I lead a team of data scientists and AI engineers at Arvato Systems in Gütersloh — we build machine-learning models, AI agents, and agent-based automations.
Over thirty years of writing software. Freelance from '96, agency life from 2001, Arvato Systems since 2005 — and the code never stopped. What you'll find here is the side of my work that lives outside office hours: open-source Python frameworks, graph-database tooling, and local-first AI agents. Composable by design. Built to last.
