About this service

Summary

I design and build complete mobile applications for iOS and Android, covering both the frontend (user interface) and backend (APIs, databases, integrations). With years of experience in Flutter, React Native, Swift, Kotlin, and Java, I deliver apps that are fast, scalable, and user-friendly.
Whether you need a cross-platform app to reach both stores at once or a fully native build for maximum performance, I’ve got you covered. I handle everything from initial concept and UI/UX design to coding, testing, deployment, and backend setup.
You’ll get an app that is clean, modern, and built to match your product vision.

What's included

  • Full Mobile App Build

    A complete, functional iOS and Android application built with Flutter, React Native, Swift, or Kotlin, aligned with your requirements.

  • Backend & API Integration

    Secure backend setup with database, API connections, and third-party service integrations.

  • Deployment Package

    App store–ready builds for iOS and Android, with installer files, publishing support, and documentation.

Umar’s been great to work with. He’s currently building our web platform and has handled everything really smoothly so far. Communicates well, quick to fix things, and really gets what we’re trying to do. The project’s still ongoing, but we’re happy with the progress and how professional he’s been. Definitely recommend working with him.

Working with Umar on our Chrome extension has been an absolute pleasure. From the start, he impressed me with his technical skill, communication, and professionalism. He quickly understood our product vision, contributed thoughtful ideas to improve the user experience, and delivered high-quality code on schedule. What really sets Umar apart is his blend of creativity and reliability — he’s not only a strong developer but also a true problem-solver who takes ownership of his work.
