At EnergyHub, I led the end-to-end redesign of the ChargingRewards app, resulting in a 46% reduction in user opt-outs and a 4.7/5 trust rating during beta—clear indicators of improved engagement and user confidence. I facilitated cross-functional design sprints, research synthesis, and product reviews to align user behavior with strategic goals like grid stability. By embedding closely with product and engineering teams, I fostered a test-driven, user-centered culture, introduced lean UX practices, and accelerated iteration cycles.
