About

I reverse engineer the products of great companies🕺🪩 every Friday Why? Doing deep dives on product-led growth, UX and user research helps me free up brain space, develop my craft and get an extra layer deeper into user psychology. I also enjoy interrogating how we work, how to focus and be productive to free up time for the other things in life.
