I hired Friendly Product to help build Yupp.ai - a site where you can access any AI model and compare different models side by side. Alex is an amazing design engineer - combining great UX taste with clean and maintainable code. He built core UX like our onboarding flow, sidebar, header, and much more. He implemented a token based design system with tailwind and paid close attention to responsive design and transitions/animations. He was meticulous in controlling changes with feature flags and running A/B tests (using Vercel Flags and Amplitude). We worked together during the rise of AI coding agents and he smoothly transitioned from writing code to orchestrating and supervising AI. Now he's a whole frontend team!
