About Me
SK
📍 Based in Germany

Hey! I'm Sulaiman — a Mobile Developer with a passion for building apps that are as delightful to use as they are solid under the hood.

I specialise in cross-platform development with Flutter and React Native, as well as native iOS (Swift) and Android (Kotlin). I care deeply about clean architecture, smooth animations, and experiences that feel native on every device.

With a background spanning startups and established tech teams across Europe, I've shipped apps across fintech, health, and productivity — and I'm always looking for the next interesting problem to solve.
