Leadership
Introduction: My Leadership Philosophy
As a UX Design Director, my mission is to create environments where people, products, and brands thrive together. I believe leadership is about empowering others, fostering a culture of trust and learning, and aligning design with business strategy to drive meaningful impact. My approach combines systems thinking, mentorship, and a relentless focus on the human experience.

“Nassos is a strong strategic thinker and has the ability to create a vision for the product that brings together deep customer insight and a strong conviction on where we want to take the experience of our users with the product. Nassos has been a thought partner to me throughout his time at Kantan and his thinking continues to shape the direction of the product. Nassos is also a great team player and has developed strong relations of trust with our product and engineering teams. I recommend Nassos to any team that is looking for a designer who can bring a strong point of view on product experience and execute it to pixel perfection.”
Leading Innovation
at Brill.app
Challenge: Professionals were losing valuable time and momentum after collaborative workshops, spending hours manually digitizing handwritten notes and sticky notes into various digital platforms and project management tools
My Leadership: Product Design Lead & Co-founder at 107% Startup Studio, I led a small team of four in creating Brill.app, a productivity application that helped professionals digitize handwritten notes 200x faster than typing. I wore multiple hats, directing product design, UX/UI design, branding, and marketing efforts while guiding the team through rapid iteration cycles.
