CashFly is a fintech web app designed for young people who are just getting started with investing and personal loans. Built on John Maeda's Laws of Simplicity, every decision was made to reduce cognitive load and make finance feel approachable. Through user research we found that the biggest barrier wasn't money — it was confusion. Too many options, too much jargon, no guidance. So we scoped the MVP down to four core actions: sign up, log in, request a loan, and invest. This constraint was the product. I led the end-to-end design process — user research, user flows, wireframes, UI design, interactive prototype, and usability testing.
