I build complete iOS apps and take on projects that arrive with a hard deadline or a problem that has been open for a while. 15 years in Swift, SwiftUI, UIKit and Objective-C, 70 contracts and 7,600 hours delivered here.
Two situations cover most of my work. In one, a client needs a single engineer to own iOS entirely: architecture, UI, integrations, App Store release, and everything after it. In the other, there is an existing codebase, something in it is wrong, and someone has to get productive in it quickly. I do both. After 70 projects I have seen most of the ways an iOS app can be assembled.
Performance is where I spend the most attention. Fast launch, content on screen immediately, smooth scrolling, flat memory, and a device that stays cool through a long session. Crash-free rate is a number I watch release over release and treat as part of what I deliver.
TECHNICAL
Swift, SwiftUI, UIKit, Objective-C, Combine, async/await, MVVM and modular architecture
Networking and real time: REST, GraphQL, WebSockets, Firebase, push and VoIP notifications
Payments: Stripe, Apple Pay, StoreKit in-app purchases and subscriptions with server-side validation
AI and ML: OpenAI and LLM integrations, Core ML, Vision, on-device inference
Media: AVFoundation, camera and video pipelines, background audio, streaming SDKs
Data and graphics: Core Data, SwiftData, Metal, MapKit and location services
Delivery: XCTest, Instruments, Xcode Cloud, GitHub Actions, TestFlight, App Store review
Backend: Node.js, TypeScript, PostgreSQL, Redis, AWS. I design and ship the server side of my own products, so on a small team you get one engineer accountable for the full stack.
INDUSTRIES
Social and dating platforms. Fintech and payments. AI-powered products. Live commerce and marketplaces. Media and streaming. Location-based services. An SDK running inside an app with over 10 million downloads.
HOW I WORK
I ask the awkward questions in the first conversation, while changing the answer is still cheap. You get a written scope and a number before any code exists.
Builds go to TestFlight regularly, so the app stays in your hands for the whole project.
I write code for the person who opens the file a year from now.
My hours overlap the US working day and I reply within a few hours.
If you have an iOS project, especially one that is technically demanding or already in trouble, send me the details. I will tell you honestly whether I am the right fit, what it will take, and how long.
