PROFILE

Marian Kannwischer

Marian developed multiple features for the RapidataAI/rapidata-python-sdk, focusing on API development, integration, and developer experience. Over three months, Marian enhanced the SDK’s evaluation workflow by introducing configurable parameters and type safety, and improved API observability with custom headers and version tracking, all implemented in Python. Marian also built a ResponseCountFilter class, enabling flexible validation task filtering with robust operator validation and seamless API model conversion. Additionally, Marian automated OpenAPI client updates using GitHub Actions and improved documentation clarity with Markdown. The work demonstrated depth in CI/CD, SDK development, and object-oriented programming, resulting in more reliable and maintainable code.
