About me
With 8+ years of experience as a Software Engineer and a strong passion for indie development, I have successfully launched 18 fully functional iOS apps, all approved and live on the App Store. My journey has been focused on building high-quality, user-centric products that solve real-world problems.
I specialize in end-to-end app development — from idea validation and architecture to deployment and post-launch optimization. I work with native iOS (Swift/SwiftUI), native Android (Kotlin), React Native, Flutter, and modern web technologies to deliver scalable and maintainable solutions.

Mateusz was great to work with throughout the project. Communication was clear, he was responsive to feedback, and delivered the app as requested. He was patient with revisions and always willing to help when questions came up. I'd be happy to work with him again on future projects.
