I help organizations design and ship robust Python backends, integration platforms, and publishing workflows. I’m an independent Python developer and software architect (Dipl.-Inf., Saarland University) with 30+ years of hands-on experience building production systems in Python (since 1993). I’m deeply connected to the Python/Plone ecosystem and combine architecture thinking with hands-on delivery. My focus: resilient backend ecosystems, integration-heavy enterprise landscapes, and digital publishing/automation—often in distributed teams and 100% remote setups. What I do • Backend & integration: REST APIs, microservices, data pipelines/ETL, database-driven applications, system integrations • Architecture & modernization: audits/reviews, target architectures, legacy modernization, risk assessment, scalability & delivery • Publishing & CMS: Plone/Zope platforms, single-source multi-channel workflows, XML/HTML/EPUB/PDF, automated PDF/PrintCSS production • AI & LLMs: LLM integrations (e.g., GPT/Claude/Llama), RAG + vector search for knowledge-driven applications Typical tech stack (selection) FastAPI, Pydantic v2, SQLAlchemy 2.x, Poetry, Ruff, Pytest; PostgreSQL/Timescale plus SQL/NoSQL; Kafka/RabbitMQ/Redis; OpenSearch/Elasticsearch/Solr. Industries & clients Energy, industry, publishing, research/universities, healthcare/medical—where complex requirements and reliability matter. I also mentor and train teams and enjoy “project rescue” situations where delivery has stalled.
