Berke A.
iOS Developer | Mobile App Development
I design and build apps end to end, from first concept to a live product. iOS first: native SwiftUI apps, designed, built, and shipped to the App Store by one person. But not iOS only: I also build the backends, APIs, and web pieces your product needs to actually run. Most projects need a designer, a developer, and someone to manage the gap between them. With me there is no gap. The person who designs your screens is the same person who ships them, so nothing gets lost in handoff and decisions take minutes, not meetings. WHAT I BUILD • Native iOS apps in SwiftUI, from scratch to App Store release • Redesigns and rebuilds of existing apps • Backends and APIs when your product needs them (Python, FastAPI, Supabase, PostgreSQL) • Web apps and landing pages when your product needs a website • Subscriptions and paywalls done right (StoreKit 2, RevenueCat) • Onboarding, analytics, and attribution set up for growth • AI features where they add real value: chat, assistants, recommendations (Claude, OpenAI) HOW I WORK Clear communication, fast iterations, honest estimates. My track record on Upwork says the same: Top Rated, 100% Job Success across 30+ completed projects. A GOOD FIT IF YOU NEED • A new app designed and built by one person, start to finish • An existing app polished, extended, or rebuilt • An MVP shipped fast to validate an idea • AI features added to your product Tech: Swift, SwiftUI, StoreKit 2, RevenueCat, Python, FastAPI, Supabase, PostgreSQL, REST APIs, OpenAI API, Claude API, App Store Connect Send me a message with what you are building and I will tell you honestly what it takes to ship it. Hope we will connect soon!
