Worked on the stapi-spec/stapi-fastapi repository to enhance the configurability and reliability of product routing within the backend system. Developed a feature that allows the RootRouter’s add_product method to forward arbitrary positional and keyword arguments directly to the ProductRouter constructor, enabling more flexible and product-specific router configurations while reducing boilerplate code. This approach maintained backward compatibility and improved consistency across product routers. The work was implemented using Python and FastAPI, demonstrating skills in API development, router composition, and clean commit practices. Documentation was updated in CHANGELOG.md to ensure clarity and traceability of the new configuration capabilities introduced.
