Product Design advisor & mentor
I help teams to build better products in less time by advising and mentoring on product, design, and leadership.
Working closely with founders and cross functional teams, I help organisations to improve impact, quality, and speed. I help teams to think bigger strategically, execute tactically with more quality, and operate with more efficiency.
I believe in the power of design to improve people's lives, blending an analytical and creative approach with a broad range of inspirations to create delightful and innovative experiences that have real meaning for the people who use them.
