Worked on the Wspolny-Dojazd/frontend-mobile repository, focusing on enhancing the robustness of the user registration flow. Addressed a critical issue in registration error handling by updating the process to extract error codes directly from caught exceptions, which improved the clarity of error reporting and streamlined troubleshooting. This targeted bug fix aimed to create a smoother onboarding experience and reduce support overhead. The work was implemented using React and TypeScript, leveraging frontend development expertise to ensure reliability in the registration path. No new features were introduced during this period, with efforts concentrated on quality improvements and maintaining code stability.
