Worked on stabilizing feed navigation and enhancing API response accuracy in the Kareadita/Kavita repository, focusing on backend development using C#. Addressed a critical issue in OPDS feed pagination by ensuring that self and next links consistently include the correct OPDS prefix and that the API key is properly concatenated on updated endpoints. This fix reduced navigation errors and improved interoperability for client applications consuming the API. Applied skills in API development and unit testing to resolve inconsistencies in pagination logic, resulting in more reliable and predictable API responses. The work emphasized robust backend practices and careful attention to integration details.
