Worked on the decolua/9router repository to enhance the AddApiKeyModal component by introducing a default model field and improving validation logic, ensuring that model IDs are correctly persisted for compatible providers. Focused on front end development using React and JavaScript, the work included robust client-side validation and error handling to streamline API key submissions and reduce user errors. Addressed a key bug in the provider API key setup, resulting in more reliable provider integrations and smoother user workflows. The approach emphasized maintainable code, clear user feedback, and version-controlled delivery, demonstrating proficiency in API integration and modern front end practices.
