PROFILE

Heiko Theißen

Over a two-month period, contributed to the cap-js/openapi and capire/docs repositories by addressing both technical bugs and documentation clarity. In cap-js/openapi, resolved a parameter alias conflict in OData OpenAPI conversions by programmatically prepending '@' to overlapping parameter names, ensuring compatibility and reducing runtime errors for downstream clients. This solution was reinforced with targeted regression tests to validate edge-case behavior. In capire/docs, enhanced OData Aggregation documentation by enforcing the mandatory use of the @Aggregation.default annotation for custom aggregates and providing a practical SUM example. Work demonstrated proficiency in JavaScript, OData, and technical documentation, emphasizing correctness and maintainability.
