Hi, I’m Choonie Chang, a product designer specializing in B2B enterprise systems, AI-driven products, and cross-functional team leadership. I enjoy translating complex logic and data into intuitive, user-centered designs that reduce cognitive load and drive business results.
In my work, I bridge the gap between technical concepts like energy, staking, and on-chain execution and practical financial products while leading design systems, mentoring teams, and delivering measurable improvements in engagement and revenue.
