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 has been applied to areas ranging from rule-based arithmetic over graph structures to large-scale ontology consistency checking — including loading the entire 1.4 TB Wikidata JSON dump for automated contradiction detection across millions of facts.
A secure, highly configurable Linux distribution for developers, featuring a custom installer and a global repository infrastructure. I architected the entire ecosystem, from the Raku-based installer to a modular package management system.
Technologies: Raku, Ansible, ZFS, Linux Kernel, CI/CD.
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.
