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.

FAQ
What is your work quality?
I can promise 100% client satisfaction.
Is the pricing fixed or flexible?
The pricing is flexible and depends on your specific project requirements. The final cost is determined based on the type of app, required features, overall complexity, design needs, and the total scope of development. After discussing your idea in detail, I’ll provide a clear and fair custom quote.

Yes. I offer post-launch maintenance and support to ensure your app continues running smoothly. Ongoing support can be arranged on a monthly basis, covering updates, bug fixes, performance improvements, and compatibility with new OS versions.
