I ❤️ solving iOS problems - big and small. You can hire me to fix a bug, implement a complex feature, integrate ChatGPT or other services or frameworks, implement a design, or write a whole new mobile app from scratch. WHAT I OFFER • I prefer setting clear milestones from the beginning of the project and delivering on time. • Communication is a top priority for me, I post regular updates on my progress. • I write top-quality, maintainable, and robust code. • I freelance full-time, and you have my full attention on your project. EXPERIENCE I’m a seasoned iOS developer with 12 years of experience making 5-star-rated apps for the iPhone, iPad, and Apple Watch. In my previous role as a full-time senior developer, I was responsible for the development of business and productivity apps - document processing, cloud storage, and online collaboration. Before I fell in love with iOS I had 10 more years of experience developing mobile applications for Symbian, Palm, and Windows Mobile. I am familiar with most standard iOS APIs such as UIKit, Foundation, SwiftUI, Combine, animations, in-apps, push notifications, MapKit, StoreKit, StoreKit 2, Sign In with Apple, etc. I can help with App Store Review guidelines and issues. I’ve used many third-party frameworks like Firebase, AdMob, Facebook SDK, Flurry, AppsFlyer, etc. Dev tools: Xcode, Git, Figma, Jira, Trello, TestFlight, Jenkins. Don’t hesitate to drop me a message. I’d love to discuss your project.
