Worked on the microsoft/omnichannel-chat-widget repository to enhance the stability and cross-platform compatibility of the Bot Framework WebChat Adapter. Focused on refining the build system by upgrading Babel dependencies and adjusting webpack and storybook configurations, enabling support for modern JavaScript features and improving reliability across web and React Native environments. Addressed a key runtime issue by applying targeted hotfixes, which reduced customer-facing bugs and streamlined development workflows. Collaborated with co-authors to improve traceability and documentation of changes. Utilized JavaScript, TypeScript, and front end development skills to ensure robust builds and maintain compatibility with evolving dependencies and platform requirements.
