ABOUT ME
Senior Mobile Developer (Android & iOS) | 14 Years of Experience
Senior Mobile Developer (Android & iOS) | 14 Years of Experience
Senior Mobile Developer with 14 years building apps to the highest quality standards, on Android, iOS, or both.
I take your app from an idea, or from half-finished code, to approved on Google Play and the App Store and ready to earn money.
What clients hire me for:
- New apps for Android, iOS, or both: native (Kotlin, Swift, Jetpack Compose, SwiftUI) or cross-platform (Kotlin Multiplatform, Flutter, React Native)
- Finishing or fixing an existing app, including apps built with AI or no-code tools
- Store rejections: getting your app approved on Google Play and the App Store
- Subscriptions, paywalls and in-app purchases, set up right on both stores
- Health and wellness apps: privacy, on-device machine learning, store policies
Proof: I designed, built, and launched my own subscription app, a posture and back wellness app, on both stores.
Not sure where your app stands? Start with an audit: you get the most serious issues and what each fix costs.
Fixed price and clear scope, so you know the cost and the delivery date before we start.
