About me
With 6+ 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.

Masteusz is a great developer, and he responds very quickly. He built a mental health app that I had previously designed on Figma, (Mendful Mind), and he is great at including all of the features and interative elements that the app needed.

Working with him has been a great experience. He brought my vision to life exactly how I imagined it and was very responsive throughout the entire process. The app required rolling video capture, replay functionality, in-app storage, and multiple UI refinements — and he handled everything professionally and efficiently.
