iOS Developer | SwiftUI & Swift | 4 Live Apps on the App Store
I build native iPhone and iPad apps in Swift and SwiftUI — and I ship them. Four apps I built are live on the App Store right now, done end to end: design, code, localisation, App Store review and the updates that follow. WHAT I HAVE SHIPPED - SecureDoc — a document vault with on-device OCR and AI. Scanning and text recognition run on the phone; nothing goes to a third-party server. 20 languages. - StillHere — a daily check-in app that tells a family their parent is okay. Designed for people who have never used an app before. 23 languages. - Vitrio — a barcode-scanning catalogue for collectors, with valuations and insurance-ready PDF reports. 11 languages. - A private in-house app for the field team of a pharmaceutical company, now in its third major version. WHAT I CAN HELP YOU WITH - Building an iOS app from scratch: MVP, prototype or full product - Taking over an existing app: bug fixes, iOS version upgrades, App Store rejections - SwiftUI interfaces, SwiftData and Core Data, StoreKit and in-app purchases, CloudKit and Firebase, widgets, on-device Vision and Core ML - Getting an app through App Store review and keeping it updated afterwards - Localisation — my own apps ship in up to 23 languages HOW I WORK I write clean, tested code in MVVM, work in Git, and I tell you early if something is going to take longer than planned. I have worked as an iOS developer in German software companies since 2022, so I am used to working inside a team and to a written spec. I speak German, English, Slovak and Czech, so European projects are easy to run with me — client calls in German included. Tell me about your app and I will come back with a plan, a timeline, and an honest opinion on whether it is worth building.
