Ryo Tsuzukihashi's profile on Product Hunt

About

Hi, I'm an iOS Engineer at ZOZO, Japan's largest online fashion retailer. My true passion lies in indie development. I love turning "what-if" ideas into reality and have shipped over 40 of my own apps, including a map to log travel memories. I'm obsessed with crafting simple and beautiful UIs, especially with SwiftUI. My goal is to enrich people's daily lives, even just a little, through the apps I build. Excited to connect with fellow makers here in the Product Hunt community!
