About this service

Summary

I build high-quality iOS and Android applications, from custom UI/UX to backend integrations, with a strong focus on performance and scalability. What makes me unique is that I’ve independently developed and launched full mobile apps end-to-end, managing architecture, design, and App Store deployment, so you get both engineering depth and product ownership in one.

FAQs

  • Can you build both iOS and Android apps?

    Yes, I develop native iOS/Android apps (Swift/Kotlin) .

  • Will you also publish the app to the App Store / Google Play?

    Yes, I handle the deployment process and guide you through the submission steps.

  • Do you work on existing apps or only new projects?

    Both! I can refactor, optimize, and add features to existing codebases as well as build apps from scratch.

  • How do you ensure quality?

    I write clean, maintainable code, use Git for version control, and conduct testing on multiple devices.
