Worked on the MetaMask/metamask-mobile repository to enhance the Card onboarding flow for US users by introducing explicit email consent terms and mandatory consent checkboxes, addressing regulatory compliance requirements. Leveraged React for front end development and applied thorough testing practices to ensure robust data consent handling. The implementation, written in JavaScript and TypeScript, aligned with the cp-7.65.0 release and focused on improving user trust and reducing regulatory risk. No major bugs were reported during this period, and ongoing monitoring was established to track downstream impacts. The work resulted in a clearer data-consent posture for US onboarding flows within the application.
