Katrin T.
Ph.D. Mathematician | High-End Technical Writer | Developer Docs
Are you looking for someone who can bridge the gap between complex engineering and crystal-clear documentation? I help technology companies, Tier-1 suppliers, and software teams transform chaotic codebases and intricate systems into structured, high-quality developer docs. As a Ph.D. Mathematician and former Senior Automotive Software Engineer (8+ years of industry experience), I don’t just write—I deeply understand the underlying code, architecture, and regulatory requirements (including ISO 26262 / ASIL B). What I bring to your project: • Docs-as-Code & Frameworks: Expert in the Diátaxis framework, Markdown, and Git-based documentation workflows. • Technical Depth: Professional experience in MATLAB/Simulink, Stateflow, and Python automation (including custom ARXML parsers). • Information Architecture: Transforming complex mathematical algorithms and system workflows into intuitive manuals and API guides. • High Security: Operating from a physically secured, fully encrypted, hardware-firewall-protected remote infrastructure. Proof of Work: Feel free to ask for my public GitHub portfolio, which features production-ready Python automation scripts, proprietary parsers, and live examples of Diátaxis-structured documentation.
