About me
I am a full-stack developer with hands-on experience in productive business systems. My current work includes Shopware 6, backend logic, REST APIs, Vue and Angular frontends and selected Kotlin adjustments for Android.
Alongside this work, I additionally support small and medium-sized businesses with service as a software, web app implementation, agentic coding workshops, software & API audits and MVP development.
Based in the Waldshut district in the German-Swiss border region, available on site for businesses nearby and remotely for everyone else.
I clarify requirements carefully, keep effort, value and risk visible, and deliver software that stays understandable in day to day operation.
I use AI-assisted development tools for research, code analysis and refactoring. The technical responsibility stays with the developer.
