About Carsten

I develop individual systems, automations, and technical workflows for digital business processes. My focus is on the conception, development, and further development of solutions that reduce manual processes, meaningfully connect existing systems, and make technical processes more stable and efficient.

I primarily work on interfaces between software, data, and operational processes – for example, in API integrations, internal tools, data processing, Python-based automations, WordPress connections, and AI-supported processes. My goal is not technical gimmicks, but solutions that actually work in everyday life and provide tangible added value.

I am particularly strong in established or complex system landscapes where standard solutions are not sufficient. I analyze existing processes, identify bottlenecks, and develop pragmatic, robust solutions that can be integrated into real workflows. In doing so, I combine technical understanding with a clear focus on efficiency, scalability, and practical feasibility.

I am looking for projects where the goal is not just to "program something," but to truly solve a problem – whether it's automating recurring tasks, technically integrating existing systems, or building custom tools for specific requirements.
