Description

I help founders, startups, and small teams fix, polish, and ship native iOS apps.

Good fit if your app is almost ready, but you are stuck with SwiftUI/UIKit bugs, Xcode issues, certificates, provisioning profiles, TestFlight, App Store Connect, Apple validation errors, API integration, or final UI polish.

I work with Swift, SwiftUI, UIKit, REST APIs, CoreData/SwiftData, StoreKit, EventKit, UserNotifications, and OpenAI integrations.

I have also published my own iOS app, Mnimi, on the App Store, so I understand the full release path from code to TestFlight to App Store review.

Typical projects I can help with:

Fixing SwiftUI/UIKit bugs
Preparing an app for TestFlight or App Store submission
Solving certificates/provisioning/App Store Connect issues
Integrating REST APIs, auth, payments, backend services, or AI features
Adding new screens or flows to an existing iOS app
Refactoring older UIKit code and gradually introducing SwiftUI
Improving UI polish, loading states, empty states, and error handling
Building a small MVP from scratch and preparing it for launch

I am best for founders who need someone practical, calm, and reliable to take ownership of the iOS side, improve the app, and ship reliably.
