These projects represent my passion for building foundational, user-empowering open-source software. They are conceived, architected, and developed under the umbrella of my company, acrion innovations GmbH.

A Logic Programming Engine Built on Graph Topology
A semantic network reasoning engine where rules, predicates, and even numbers are first-class nodes in the graph — making logic and data structurally identical.
zelph reasons over the complete Wikidata dump on a single machine and has surfaced thousands of consistency violations in collaboration with the Wikidata Ontology Cleaning Task Force. Version 1.0 runs in the browser as WebAssembly, ships prebuilt for Linux, macOS and Windows, and embeds into a host application through a C ABI with a Rust layer on top. The work is funded by NLnet’s NGI0 Commons Fund.
A secure, highly configurable Arch-based distribution featuring a custom installer written in Raku. Everything the installer knows – every setting, dependency and lifecycle script – is declared as data in a separate repository rather than written as code, so an improvement reaches new installations without a new medium. The package repository is rebuilt from upstream recipes, reviewed, signed and published only as a complete set, and every run of that pipeline is public.
A high-performance C++ library for concurrency, paired with a Lua extension that enables true hardware multithreading. I designed the innovative shared-memory approach and the multi-core extension for Lua.
A Qt desktop application for image processing built on a powerful, asynchronous plugin system. The architecture keeps the UI responsive by offloading all heavy lifting—from I/O to interactive tools—to non-blocking Lua plugins.
A common misconception about Open Source is that it’s only for hobbyists. In reality, professionally managed Open Source offers immense value to commercial enterprises. My projects are available under a dual-license model:
AGPL 3.0+ License: You are free to use, modify, and distribute the software — including for commercial purposes — provided you comply with the terms of the AGPL.
Commercial License: For organizations that need closed-source integration or have special requirements incompatible with the AGPL, a commercial license is available.
Importantly, the dual-license model does not restrict users of the open-source license. The AGPL grants full rights, including commercial use. The commercial license is an additional option designed to support integration needs that go beyond what the AGPL permits.
For inquiries about commercial licenses, dedicated support, or custom development, please see the offerings on my company website.
