iOS App Development Consultant
Work directly with a senior iOS developer on Swift, SwiftUI, Firebase-backed products, StoreKit, Apple Vision, codebase rescue, TestFlight/App Store launch paths, and product decisions that need more than generic implementation help.
This page is for teams that already have an iOS app, an MVP in motion, or a serious plan to build one. The work is practical: review what exists, identify the highest-risk parts of the app, clarify the backend and release path, and then build or stabilize the parts that move the product forward.
Take over an iOS codebase that is unstable, hard to release, difficult to change, or blocked by bugs and unclear architecture.
Build a focused iOS MVP with the right amount of architecture, Firebase/API integration, analytics, StoreKit, and release planning.
Review Firestore structure, Cloud Functions usage, authentication, media storage, and read/write patterns before costs or bugs grow.
Prepare TestFlight builds, App Store submissions, release checklists, crash fixes, and user-facing launch blockers.
Review SwiftUI state, UIKit transitions, Combine flows, MVVM boundaries, backend contracts, tests, and maintainability risks.
Implement targeted features inside an existing iOS app without turning the engagement into an open-ended rewrite.

Connect iOS features to Firebase, Node.js APIs, authentication, storage, push notifications, StoreKit, AVKit, MapKit, HealthKit, WatchKit, and analytics.
Find the real blocker in an existing app: architecture debt, release issues, performance, broken state, bad data shape, or missing ownership.
Move from review to implementation when the next step is clear, with direct communication and no junior handoff.
Yes. A focused review can cover code structure, Firebase/API usage, release readiness, crash risk, and what to fix first.
Yes. MVP work can include SwiftUI development, backend setup, core workflows, TestFlight, and App Store launch support.
No. Consulting can include hands-on implementation, cleanup, debugging, architecture, and technical planning.
