Worked on the OvidijusParsiunas/deep-chat repository to enhance the submit button user experience, focusing on accessibility and mobile usability. Addressed issues with input focus restoration after submission, ensuring that mobile keyboard visibility is maintained and user flow remains uninterrupted, particularly on mobile Safari. Leveraged TypeScript and front end development skills to implement tabindex improvements for better keyboard navigation and screen reader compatibility. Introduced cross-browser checks to stabilize focus behavior, reducing friction for users submitting contributions across different platforms. The work concentrated on a single feature, demonstrating attention to detail in accessibility and cross-browser consistency without addressing bug fixes during the period.
