I've been working as an iOS Developer for 14 years. Experienced in both Swift and Objective-C, I have developed apps for the iPhone, iPad, Apple Watch and Apple TV. I've worked on Android too, both Java and Kotlin. I have submitted many apps to the App Store, with complex interfaces, extensive web service communication, and multimedia content. Some of these apps got good references in the press, and one of them, Back in Time, was selected by The New York Times as one of the Top 10 iPad apps of the year.

🧠 I don’t just code — I lead builds to launch. 🔧 Complex apps. Clean handoffs. No noise. 💼 Apple-level quality, on your team. *** About Me *** I've worked as a senior iOS developer and technical lead for the last 14 years including working on an internal project at Apple. Previously I've worked on mobile apps across a number of different sectors with clients such as RBS, Sage, McDonalds, WIlliam Hill, and Roche / Genentech in the pharmaceutical space. More recently I've become specialised in Open AI (ChatGPT) having created the CodeBrain for Mac based on Open AI / Chat GPT. I'd be happy to look at taking on your mobile projects.

I've been at it since 2009 — developing iOS apps for startups, software development agencies, and large corporations. I'm great with UI & UX design, and specialize in audio and music software. App development is often an exercise in striking a balance between the ideal functionality and what can be achieved within a short timeline. The objective is to minimize time and effort while providing an exceptional user experience. I enjoy this balancing act — it's the core of the value I provide to my clients, in addition to clean & easily maintainable code, and interfaces that look and feel sublime. Services: • iOS Development • UI & UX Design • Music & Audio Apps Languages and frameworks: • SwiftUI, UIKit • Swift, Objective-C, C, C++ • Core Audio, AVFoundation, AudioKit, and a trillion other frameworks Tech: • In-App Purchases / Subscriptions • API Integration • REST APIs • Supabase • Firebase • Localization • Analytics • Unit Testing • CI/CD • Xcode • Git If you have an app, an idea, or both — let's connect!

As the iOS developer with over 9 years of experience in native app development, I have honed my skills in Objective-C and Swift, utilizing XCode to create robust, efficient apps that stand the test of time. My expertise extends to working with third-party SDKs and API schemas, ensuring seamless integration and optimal app performance. I am well-versed in the latest technologies and frameworks, including SwiftUI, Combine, MapBox, GoogleAd (including AdMob)/FB AD, Firebase, Azure SDK, AWS, and various third-party APIs (Google, payments, Facebook, Twitter, statistics services, custom services, etc). An Agile approach to software development is my preferred methodology, and I am adept at utilizing sprints, reports and other Agile tools such as Atlassian services (Jira, Confluence), Basecamp, and Trello. I am proficient in version control systems such as GitHub and Bitbucket and have extensive experience in GIT and SVN. I feel very confident working with Figma or Adobe services. To ensure the best possible user experience, I own multiple devices to thoroughly test the apps I develop. While I am primarily seeking long-term partnerships, I am happy to assist with short-term projects as well. Let's work together to bring your iOS app vision to life.

Senior iOS developer with 15+ years building native apps - from small MVPs to products used by tens of millions. I work solo as the sole developer on every project, combining deep engineering depth with senior business leadership experience (VP roles at companies like Activision Blizzard). $1M+ earned on Upwork as a non-agency developer, 100% job success score for over a decade, Top Rated Plus, and Expert Vetted. Whether you're launching something new, rescuing a stalled project, or evaluating AI-built code before shipping, I bring both the technical judgment and the business context to help you make decisions that hold up.

When you hire me, you get 15+ years of senior judgment applied to every line of code. ◆ Why Work With Me • 15+ years building iOS apps with millions of users. • Expert in Swift, SwiftUI, Objective‑C, and services like Firebase, AWS, RevCat, AdMob, and APIs. • AI-assisted development used deliberately, with senior judgment on quality and architecture. • Business fluency in budgeting, product strategy, and communication. • PMP certified; led 7‑figure projects at companies like Activision Blizzard. • Honest recommendations, even when that means pushing back or suggesting a different path. ◆ Services • End-to-End iOS Development: From concept to App Store launch. • AI Code Cleanup: Stabilizing and refining apps built by AI into production-ready products. • Project Rescue: Fix bugs, refactor code, modernize UI/UX, and get stalled apps back on track. • AI-Powered Features: Intelligent text, image, and voice capabilities to give your app a competitive edge. • App Store Strategy: Compliance, monetization, and feature planning to maximize success. ◆ What Clients Say (150+ Five-Star Reviews) "Scott is truly outstanding. Extremely skilled, great communicator, professional, ethical, resourceful, dependable, responsive. A huge asset and leader for any project." - Native iOS App (1,035 hrs, 5.0⭐) "Scott is a rockstar.

I will definitely work with him again." - Native iOS App (592 hrs, 5.0⭐) "Scott is the 'total package' - responsive, skilled, fair, detail-oriented and many more positive attributes. I would highly recommend him for any project." - Apple TV App (403 hrs, 5.0⭐) ◆ Let’s Build Something Great Every project I take on gets my full attention - I work solo, limit the number of simultaneous clients, and stay engaged from the first call through delivery. If you want to talk through your project, I'm happy to start with a short call or my 1-hour consultation. Either way, no pitch and no obligation.

I build iOS apps that make money. If yours doesn't, we should talk. Most iOS developers ship features. I ship revenue. In the last 8 years, apps I've built have generated $500K+ for my clients, not because I write "clean code" (everyone claims that), but because I obsess over the 3 things 90% of developers ignore: conversion, retention, and App Store ranking. What I actually do: Build native iOS apps in Swift/SwiftUI that get featured, ranked, and downloaded. Then I make sure they don't leak users through a bad onboarding, broken paywall, or App Store listing nobody clicks. A few receipts: - Telehealth app → 10K patients, $500K seed round (HIPAA-compliant, Core Data, CloudKit sync) - DTC e-commerce app → 312% mobile revenue lift (Apple Pay, custom checkout that doesn't suck) - EdTech app → 4.9★, featured in "Apps We Love" (SwiftUI, built in 7 weeks) - Social app → 50K DAU, 1M+ messages/day (Firebase, real-time, zero downtime in 18 months) How I work: I don't take every project. I take 2 per quarter. If we're a fit, you get: - A working TestFlight build in week 2, not week 8 - Direct access to me, not an account manager - An opinionated partner who'll push back when your idea is wrong (and tell you why) - A 99.8% crash-free app, or I fix it on my dime I'm probably not for you if: - You want the cheapest developer on Upwork (I'm not) - You need someone to just "code what I tell them" (I'll ask why first) - You don't have a clear sense of who your user is (I'll help, but you have to care) I'm exactly right for you if: You've got a real product, a real budget, and you want it built by someone who's shipped apps that people actually use and pay for, not someone padding a portfolio.
