Hey 👋 I'm JB
From entrepreneur to design leader, I bridge business and design to build SaaS products that users love and companies rely on.
With 10 years in product design & management, I’ve launched two products from scratch and now lead a team while shaping the design culture at Greenly, a fast-growing climate tech startup.
