In April 2025, Brian developed a responsive Feedback Tab Survey for the PostHog/posthog-js repository, focusing on enhancing accessibility and usability across devices. He implemented the feature using JavaScript and TypeScript, applying front end development and UI/UX skills to ensure the survey adapts seamlessly to various screen sizes. Brian introduced cross-viewport tests to verify consistent display and adjusted styling for small screens, directly addressing mobile usability challenges. The work aligned with product goals to increase feedback capture and improve user experience on both desktop and mobile. Over the month, Brian delivered one feature with a thorough approach to testing and design.
