About this gig

Are you looking to build a custom iPhone app for your business? You are in the right place.

I'm Jonathan Ansumana, an iOS developer with 6 years of corporate experience building apps for companies like Blue Cross Blue Shield of CA and Empower Retirement. I have two published apps live on the App Store and a CS degree from Principia College.

I specialize in building custom iPhone apps for businesses, sports academies, fitness studios, booking platforms, and entrepreneurs who need more than a template can offer.

What I build:

  • Booking and scheduling apps
  • AI-powered iOS apps
  • Business management platforms
  • Consumer apps with subscriptions and in-app purchases
  • Multi-user apps with roles, messaging, and push notifications

Every app is built natively in Swift and SwiftUI for the best possible performance and App Store approval rate.

What makes me different:

  • 6 years of corporate iOS experience
  • 2 published apps on the App Store right now
  • Fixed price, no hourly surprises
  • I personally build every app, no outsourcing
  • App Store submission handled end to end

Message me before ordering so we can make sure your project is a perfect fit.
