Heajung L.
App & Web UI/UX Design Specialist
If your app or website isn't converting, your design is the problem. Most apps look fine. Very few are designed to keep users coming back. Poor UX doesn't just frustrate users. It kills retention, tanks conversions, and quietly drains your revenue every single day. That's exactly what I fix. I design app and web experiences that don't just look good. They move people to act. Whether it's a SaaS dashboard that makes complex data feel simple, an onboarding flow that turns sign-ups into loyal users, or a landing page that triples your subscribers in 3 months, I design with your business outcome in mind, not just aesthetics. My work has helped products reach 1M+ downloads, rank #1 on the App Store, and attract enterprise clients like McDonald's. I've also received collaboration proposals from Samsung and Deloitte through my own design studio. If you need ✅ App UI/UX that increases retention and engagement ✅ SaaS dashboards that make complex data feel intuitive ✅ Web pages designed to convert visitors into customers Then let's talk. Drop me a message and let's figure out exactly what your product needs.
