SUMMARY

I have been crafting digital products, leading teams, and working with founders on delivering efficient and elegant solutions since 2012.


My journey includes leading product design for Whoz (€30M Series A), revolutionizing AI coaching at Luminous, and building the future of GenAI creator economy at Uncut Network.


With a unique blend of technical expertise, artistic sensibility and business mindset, I have helped numerous companies scale from zero to one, and beyond. These experiences have taught me how to navigate complex challenges while maintaining a relentless focus on user needs and business outcomes.

DESIGN PRINCIPLES

Simple Focus

I define focus as the pursuit of deep simplicity as opposed to a complexity that remains shallow. This raises a fundamental question: how profound can a simple concept become?

Large Spectrum

Good design never happens on its own. Not only collaboration is needed, but a wide-angle view and an honest curiosity to understand the multidimensional nature of the problem we are solving, and how to engineer it.

Behavioral Drives

Understanding the complex shapes of user motivations. By drawing from psychology and philosophy, we can connect with deeper human drives and higher meanings that truly resonate.
