Worked on moltbot/moltbot to enhance chat delta-stream handling and privacy within the user interface. Focused on implementing privacy-preserving delta-only assistant streams, ensuring that internal context remained protected while maintaining accurate projection of delta events. Used TypeScript and front end development skills to sanitize and safely merge assistant streams, preventing data leakage and improving the reliability of live chat. Addressed rendering and projection issues in the TUI, resulting in a more stable and user-friendly streaming experience. Emphasized testing throughout the process to align with product goals for safer, more reliable chat interactions and improved overall user experience in the application.
