Available to hire
CEO / Project Manager / Developer at Trigonella GmbH (self-employed). I build practical machine-learning and NLP systems, ranging from production-grade data pipelines and RAG assistants to domain-specific solutions in education, finance, healthcare imaging, and media intelligence.
I care about requirements, documentation, transparency, and rapid delivery of business value. My work combines solid software engineering (Python/PHP/SQL/CI/CD) with modern ML/LLM tooling (PyTorch/TensorFlow, transformers, LangChain/RAG), and I enjoy turning complex constraints into usable products for real stakeholders.
