I am William Kearns, a product designer specializing in growth design with a passion for creating user-centered solutions that drive meaningful business outcomes. My approach combines deep user research with strategic business thinking, leveraging techniques like comprehensive diary studies, usability testing, and data analysis to create products that solve real problems while accelerating growth. Through projects like the PalFlicks movie-saving app, Netflix content discovery research, and Nintendo Switch mobile app redesign, I've demonstrated my ability to identify market opportunities, conduct extensive user research (including a 4-week study with 25 users generating 500+ insights), and translate complex feedback into actionable design solutions that drive measurable results—such as achieving 47% immediate user adoption intent and successfully launching market-ready platforms.
What sets me apart is my ability to see projects through from initial user research to validated, business-impacting solutions. I excel at moving between strategic thinking and detailed execution, whether I'm conducting user interviews, building prototypes, or designing growth-focused features like matchmaking systems and reward mechanisms. My unique combination of creative problem-solving, analytical thinking, and business acumen allows me to create experiences that don't just delight users but also drive key performance indicators like user acquisition, engagement, and retention. I'm passionate about partnering with teams that value data-driven design strategies and want to build products that make a meaningful impact on both users and business objectives.
