PROFILE

Jan Svager

Over a two-month period, contributed to the gooddata-ui-sdk and gooddata-python-sdk repositories by building robust UI components and enhancing analytics model capabilities. Focused on modularizing React components, improving type-safety with TypeScript, and refining documentation to streamline onboarding and reduce risk. Refactored the UiTreeView for maintainability, introduced stricter interaction guards in UiListbox, and aligned Semantic Search documentation with SDK usage. In the Python SDK, implemented support for NUMBER analytics parameters through declarative modeling, updated the API client for new type discriminators, and ensured stable parameter persistence. Work emphasized API development, component architecture, and thorough unit testing across JavaScript and Python.
