Frontend Developer · Depok, Indonesia

I turn complex into clickable.

I'm Reihan — a frontend developer from Depok who gets oddly excited about clean components, smooth interactions and messy data turned into screens that just make sense. Four years in, I still love the moment a design finally clicks in the browser. And if the API isn't ready yet, I'm happy to go build it.

Things I've built (and polished until they felt right).

Four projects, four very different problems. Some live behind company logins, so the screenshots are blurred where they need to be.

↑ Yes, that's really me. The hair is usually this cooperative.

03About

The short version.

Frontend engineer since 2022, shipping to production while earning my Informatics degree. I work on data-heavy apps — geospatial maps, daily-use dashboards, multi-role approval flows — and make that complexity feel calm. I cross into the backend when needed (Go, Laravel), but the frontend is home.

Off the keyboard: you'll find me on a motorbike ride or deep in a game — both surprisingly good for untangling a bug I left at my desk.
