Hi, I’m Michael — I build iOS apps people love.
With over a decade of experience in iOS and full-stack development, I help startups and enterprises bring their ideas to life. By blending clean, elegant design with seamless performance and fine polish, I create intuitive products people love — apps that feel effortless to use and at home on every iPhone.
my services
iOS Development
Native Swift and SwiftUI development, from prototype to polished App Store release. I build apps that feel effortless, fast, and delightful to use — designed to match Apple’s quality standards and delight your users.
App Architecture & Development
Behind every great app is a solid foundation. I build iOS apps using Swift and SwiftUI with clean, scalable architecture that’s built to last. Whether you’re launching a simple MVP or a complex product, I focus on writing maintainable code that keeps your app reliable, fast, and ready to grow with your business.
UI Implementation & Polish
Design is more than looks — it’s how your app feels in the hands of your users. I translate your designs into pixel-perfect, interactive screens, adding the animations, transitions, and details that make an app feel truly Apple-like. Even if you don’t have a finished design, I can help refine your vision and ensure the final product feels intuitive and delightful to use.
App Store Readiness
Getting an app into the App Store takes more than just coding. I guide you through testing, optimization, and the submission process so your app is fully prepared for launch. From beta testing with TestFlight to meeting Apple’s guidelines, I make sure your app not only looks great but is ready to impress users from day one.
Bug Fixing & Stability
Crashes and performance issues can damage trust and drive users away. I quickly identify and resolve bugs, optimize performance, and improve reliability so your app feels fast and dependable. The goal: an experience your users can count on, every time they open it.
Upgrade & Modernize
Technology moves fast, and iOS is no exception. I help you update older apps to modern standards — refactoring legacy code, migrating to Swift and SwiftUI, and improving compatibility with the latest iOS versions. The result is an app that feels current, performs better, and is ready for the future.
Maintenance & Updates
A successful app evolves with its users. I provide ongoing updates, feature enhancements, and App Store compliance to keep your app competitive. Whether it’s releasing new features, adapting to iOS changes, or ensuring smooth performance, I help your app grow alongside your business.
App Lifecycle Support
Apps don’t stop at launch. They need care, updates, and sometimes a fresh perspective. I step in at any stage of the journey — whether your app is brand new, mid-development, or already live in the App Store. From fixing critical bugs to modernizing outdated code, I make sure your app keeps running smoothly and continues to delight your users.

I collaborated in a cross-platform team to make Peacock one of the most stable apps across devices at release.
