Experience
Grown systems instead of clean slide decks
My projects rarely start from a blank slate. Typical contexts are existing websites, shops, ERP and CMS landscapes, internal tools and production systems that need to keep running while they are improved.
PHP · REST/GraphQL · ERP · Shop
Product data and inventory between shop and ERP
Context: product master data and inventory across shop and ERP systems. My contribution: a web tool and integration layer for data maintenance, inventory synchronization and system handovers. Technical foundation: role management and a separate integration layer. Implemented function: maintain data and pass it to shop and ERP systems.
Own practice lab · OpenClaw · GitHub
AI assistants in my development workflow
Context: recurring research, code analysis and website work. My contribution: agent workspaces with repository access, tests and GitHub tools. Decision: changes go through feature branches and pull requests; merging and production changes require my approval. Implemented function: reviewable changes with validation evidence. My own practice lab, not a client project.
TYPO3 · SAP S/4HANA · Middleware
Connecting a CMS to business software
Context: a TYPO3 platform with SAP integration and large datasets. My contribution: form and process data synchronization, plus performance work. Technical decision: separate CMS and backend logic. Implemented function: process form and workflow data across the systems.
Open-source engineering · EPoSe
A development series on identities, service proofs, rewards, queues and verification. A technical competence example, not an AI client project.
Shopify · Themes · Conversion · E-Commerce
Shopify shops built to convert
At coolmobility, I worked extensively on Shopify shops, built themes and optimized existing shops for performance, user flow and stronger conversion.
Python · C++ · MQTT · Docker · AI
Industry: Smart-Camera Quality Control
Production-adjacent application for automated defect detection, data logging and monitoring in an industrial environment.
Linux · CI/CD · Migrations · Community
Long-Term Operation of Grown Platforms
Technical maintenance, performance, security and further development for web systems that need to run reliably for years.
