Rainer Dev Portal Portfolio

Bridging the gap between complex code and clear communication through interactive API design.

Interactive API Documentation

I specialize in transforming static OpenAPI/Swagger specifications into dynamic, interactive API explorers. By integrating live sandboxes, I allow developers to test endpoints directly from the documentation.

Documentation Engineering

I build and maintain documentation as code using Docusaurus. This includes managing complex build pipelines, versioning, and extensible plugin architectures to ensure docs scale with the product.

Developer Experience (DX)

My focus is on creating tools that engineers actually enjoy using. I bridge the gap between complex backend logic and clear, actionable communication to reduce developer friction.
