Developed a guest checkout feature for event registration in the adobecom/events-milo repository, enabling users to RSVP without logging in when guest-checkout metadata is enabled. The implementation focused on front end development using JavaScript, introducing a customer-facing flow that maintains security while reducing friction for non-logged-in participants. The solution included metadata gating to control feature exposure, ensuring that logged-in user flows remained unaffected. All changes were isolated and thoroughly documented, supporting product goals to increase event participation. The work demonstrated attention to maintainability and deployment readiness, with a clear emphasis on user experience and alignment with broader product objectives.
