As a User Experience and Interaction Designer, I create innovative software with human-centered design. At any stage of the product development lifecycle, I strengthen ideas and deliver results with a research-driven methodology. Through interviews, prototyping, and experimentation, I efficiently derive essential customer insight. Guided by data, I design tailored web and mobile experiences that give users a feeling of familiarity and empowerment. I work independently or in tandem with your team to transform concepts into success-ready products.
