Apple Developer for Hire: I Build Your App to Apple's Rules and Ship It to the App Store

I build iPhone and iPad apps that follow Apple's design and review guidelines, and I manage the entire Apple process, from opening your developer account to publishing on the App Store.

Why hire an Apple developer?

Getting an app onto the App Store takes more than writing code: if the Human Interface Guidelines-compliant UI, privacy disclosures (the privacy nutrition label), permission prompts, in-app purchase rules and App Review feedback aren't handled correctly, an app can sit unpublished for weeks.

I set this process up correctly from day one: account and certificates, bundle ID and code signing, closed testing with TestFlight, store copy and screenshots, review and release management. Example: Ezan Vakti – Gümüşpala Hizmet is live on the App Store.

Apple Developer Program account: individual or organization?

For your app to appear on the App Store under your company name, you need an organization account, which requires a D-U-N-S number. With an individual account, the seller name is the person's name. I help with account setup, team membership and permissions; the app and its source code stay in your account.

What I build

Apps that use the camera and on-device AI (CoreML, Vision), security apps (iPhone spyware detection), mobile POS and inventory for businesses, location- and notification-based content apps, and iOS clients for SaaS products whose backend is already in place.
