Hi, I'm Juliansyah.
I Build What Designers Dream and Engineers Ship
Frontend Engineer with a Design Edge
Most developers hand off to designers. I don't. I write production-ready frontend code and design the interfaces myself — which means less back-and-forth, faster delivery, and products that look intentional because they are.

About Me
Frontend · UI/UX · Flutter
I design and build the interfaces people actually touch.
I'm a frontend engineer and UI/UX designer who ships for the web with React & Next.js — and for mobile with Flutter. I care about the details most people only feel: timing, spacing, motion, and the small moments that make a product feel considered.
Designing and coding the same screens means less hand-off friction, faster iteration, and interfaces that ship looking exactly the way they were imagined.
UI / UX Design
I design the screens before I build them — wireframes, design systems, and interactive prototypes.
