    How efficient navigation solved our biggest reordering obstacle

    • Navigation Navigation
    • Product design Prod. design

    I identified that reordering users were repeatedly navigating between the product list and order history through a hidden hamburger menu. I designed and tested a bottom nav bar that brought key sections within reach, validated with real data, and iterated to make reordering faster and easier.

    When discovery became a team sport

    • Ways of Working W.o.W
    • UX research UX research

    A simple ritual changed the way our team worked. Insights coming out of discovery rarely reached the people building the product and I wanted to fix that. I designed and led the concept of Hotjar Watchparties, where developers and designers observed real user struggles together and built shared ownership over the solution.

    I led the end-to-end redesign of Interbank's Visa Premia loyalty program, for users who were just warming up to online banking and were skeptical of big banks. Through multiple rounds of interviews and design iterations, we turned a program people had stopped using into one that doubled coupon redemption in six months.

Design principles

Basically how I see, understand and practice design

Design is a mindset, not a role

Design becomes most powerful when it stops being the responsibility of a specific team and starts being a shared way of approaching problems. My work aims to balance equal parts design mindset and craft.

Design should be experienced

First-hand experience along the design journey creates a different kind of understanding. Getting the right people into the process, not just the output, is one of the highest-leverage things a designer can do.

Design is also the environment

The culture, the collaboration, the way a team shares information and makes decisions are all design problems too, and I've found that some of the most meaningful changes I've contributed to had nothing to do with a screen.
