Engineering
Lab
This is where it gets technical. When off-the-shelf software is not enough, we build it ourselves — type-safe in Rust, from API integration and document management to our own operating system kernel. What we recommend, we first put into production ourselves.
- 01
Custom Software Engineering and DMS Solutions
- Agile development of bespoke custom software with clean version control.
- Development and integration of API interfaces for end-to-end automation.
- High code quality in line with modern programming and security standards, including common license models (Apache, GPL, MIT).
- Introduction and system integration of document management systems (DMS).
- GDPR-compliant workflows and granular access management within the DMS.
How we have already done this
- Tailored fullstack software in Rust (server plus WebAssembly).
- Incoming invoices automatically detected, extracted and coded to accounts.
- E-invoices generated, checked and validated (ZUGFeRD, XRechnung).
- Travel expense web app with receipt OCR and locally operated AI.
- Real-time data pipelines and automated API integrations.
- Document management system built and integrated.

Ten projects in detail
Enterprise platform, own kernel, operating system, post-quantum crypto, e-invoice validation — clients anonymous, technology open.

Built in Rust
This website itself: Rust from the HTTP server to the animation, delivered as WebAssembly, with a post-quantum-encrypted API.
Under the hoodTool
Check e-invoice
Validate XRechnung and ZUGFeRD free of charge against EN 16931 and the KoSIT rules. Prototype in Rust/WASI — nothing from the file is stored.
