I’m a design leader, problem solver, and product innovator passionate about crafting experiences that people love. With over 9 years of experience, I thrive at the intersection of design, technology, and business, creating products that are not only functional but delightful. I believe great design starts with asking the right questions, challenging assumptions, and pushing boundaries. Whether it's leading a team, refining a strategy, or getting hands-on with design, I bring a human-first approach to everything I do. Let’s create something amazing together!
