Mobile App Development: iOS, Android and PWA from a Single Developer

I turn your idea into a product that runs on the App Store and Google Play, including the API and admin panel behind the app.

Quick answerMobile app development is the process of designing, building and publishing apps to the stores on iOS, Android or as a PWA. Hakan Sevimoğlu is a mobile app expert who delivers the mobile app end to end, together with its backend, API and admin panel.

Choosing the right platform

The right platform is different for every project: I recommend native iOS/Android for projects that need hardware access and performance, and a PWA for content projects that call for a fast launch and a single codebase. The choice is made by weighing budget and target audience together.

An app's success doesn't depend on its screens alone; a secure API, a scalable database and an easy-to-use admin panel are delivered as part of the same project.

What I offer

  • Native iOS

    App Store apps built with Swift/SwiftUI.

  • Native Android

    Google Play apps built with Kotlin.

  • PWA

    Installable web apps that work offline.

  • Backend & API

    Secure REST APIs with PHP/Laravel or Node.js.

  • Admin panel

    Content, user and order management.

  • Launch & ASO

    Store listing copy, visuals and release management.

Frequently asked questions

How long does it take to build a mobile app?

Usually 4–8 weeks for an MVP; multi-module enterprise apps are completed in stages over 2–4 months.

What affects the price of a mobile app?

The number of platforms, the number of screens and features, integrations and the need for an admin panel determine the price.

PWA or native app?

Native if hardware access and store visibility matter; a PWA is a good fit for a fast, lower-cost launch.

Is there support after the app launches?

Yes; ongoing support is provided for operating system updates, bug fixes and new features.
