Senior🎓
Top SchoolJeff Zych is a humane designer and technologist with 16 years of experience crafting developer and product experiences from code to strategy, now leading PB & J Designs as Owner & Principal Designer in San Francisco. He helps founders validate and launch 0→1 technical products through user research, rapid prototyping, and scalable design systems, drawing on leadership roles at LaunchDarkly, Optimizely, and Pragma where he built design teams and shipped revenue-generating initiatives. Jeff excels at designing non-UI developer flows and APIs, translating complex backend concepts into usable developer experiences, and has repeatedly created design systems that speed delivery and improve consistency. He pairs hands-on UI engineering roots with formal HCI training from UC Berkeley, enabling pragmatic designs that are both usable and implementable. Notably, he’s moved between individual-contributor and executive design roles, hiring and mentoring dozens of designers while still doing deep, craft-level design and prototype work himself.
