During January 2025, Alex Mac delivered a targeted user interface enhancement for the acm-ucr/cvdsa-uoft-website repository by adding a prominent 'JOIN NOW!' call-to-action button to the Example Component. Working with React and TypeScript, Alex focused on component-based design and CSS styling to ensure the button featured a rounded border, large text, and optimal placement below existing content, aligning with established design guidelines. The implementation was contained to a single file, minimizing risk and simplifying code review. This change aimed to increase user engagement and onboarding conversions, demonstrating Alex’s proficiency in front end development and thoughtful, low-impact feature delivery.
