//Creative solutions. //Stable software. //Robust systems.

I develop software as C#/.NET and Python services as well as web APIs, usually complemented by web UIs to make data flows, results and relationships visible. At the core are APIs, data models and JSON contracts as interfaces used in applications and processes.

For APIs, I handle request/response, error cases, logging/tracing and versioning – and ensure that interfaces are coherently embedded in the overall architecture and interact reliably with other components. When required, data is persisted reliably (database/storage).

When dealing with different formats, I apply parsing and mapping logic to derive a shared data model. Two examples are the OCR‑webservice (document analysis with structured JSON output) and the AI demo (product digitization: multi-image analysis with structured JSON output for downstream processes) – each with a UI layer on top, implemented in React/Next.js.

I’m generous when it comes to making things visible quickly (demo/showcase), but meticulous about details such as error messages, edge cases and contracts – because that saves time later.

I work in close collaboration: short paths, fast feedback and an iterative approach.

I’m open to new projects and contacts – especially when we jointly turn requirements into something concrete: processes, software or products.
