Mobile App Development

Build for the device people never put down — native Android and iOS, or cross-platform with one codebase.

Why it's in demand

High-value niche with far fewer capable engineers than web

Realistic timeline

Mobile is where most of the world meets software first — especially in markets where the phone is the only computer someone owns. It's also a smaller talent pool than web, which works in your favour.

Pick one lane to start. Android with Kotlin, iOS with Swift, or cross-platform with React Native or Flutter. Shipping one finished app teaches you more than sampling all four.

What you'll be able to do

Ship a real app to the Play Store or App Store
Work across Android, iOS or both from a single codebase
Own a product end to end, from idea to store listing
