As Lead Design Technologist for AIG's Annuities redesign, I created over 100 high-fidelity, responsive prototypes that served as the development team's source of truth. I pioneered innovative solutions for complex financial data displays, particularly focusing on making dense tabular information fully responsive across all devices. Working within Agile sprints, I translated Sketch designs into production-ready HTML and CSS, while "designing in code" to determine how layouts would behave across different viewport sizes. My prototypes enabled seamless collaboration between our New York design team and offshore development team, ensuring consistent implementation of sophisticated UI patterns across the entire platform.
