    I've been working as an iOS Developer for 13 years. Experienced in both Swift and Objective-C, I have developed apps for the iPhone, iPad and also Apple Watch. I've worked on Android too, both Java and Kotlin. I have submitted many apps to the App Store, with complex interfaces, extensive web service communication, and multimedia content. Some of these apps got good references in the press, and one of them, Back in Time, was selected by The New York Times as one of the Top 10 iPad apps of the year.

    Thank you for viewing my profile! I am a professional iOS developer with over 10 years experience in this field, but worked with other technologies as well in the last decade. Since developing apps for the iPhone and iPad I had the pleasure of both working in a large company, but also as a successful freelancer on small and medium size projects. My portfolio lists only a handful of apps I've had the chance to work on. I'm looking for clients that are seeking experience and quality in iOS development. I took 2nd place in the iOS Programming Test. Looking forward to working with you!

    I build web apps on React as well as iOS apps with Swift. Need a website (or web app) and a native iOS app? No problem! I love Swift and SwiftUI! Started my professional path as an iOS Dev and still making progress in this area by bringing more great ideas to life. My app Timerange currently has more than 40 000 users around the globe and a new app Courset is getting more and more attention. I’m currently doubling down on SwiftUI, writing all my latest apps using this framework, and I also inject SwiftUI into my older UIKit based projects. I also have good experience (5+ years) of writing efficient web apps on React, as well as complex websites on Next.js. I have a sense of good UX and UI, so I approach every mock-up very thoroughly.

    Hello! I'm Boris, a Senior iOS and Android developer with 8 years of experience in big tech companies✌️ - Senior iOS Developer - Senior Android Developer - Advanced in Kotlin Multiplatform - Compose Multiplatform (similar to Flutter, but native for Android) My main competence is the development of high-load corporate messengers. Here are three complex challenges I've tackled throughout my career: 1. Developed a new encryption module for messenger application, enhancing communication security within the company. 2. Architecting applications based on Kotlin Multiplatform to ensure a single source of truth between iOS and Android platforms (core functionality such as network layer, data storage, as well as business logic up to the common ViewModel and data model). 3. Infrastructure tasks, such as expediting project build times through modularization, as well as implementing CI/CD setup. However, I also work on simpler projects: - Utility applications - Subscription-based services - Shopping and delivery apps Since I've led teams, I have strong competencies not only in development but also in UI/UX design and analytics. I can help you create a well-thought-out technical specification, design a prototype of the application with animations and interactivity. All this will save you money in the future, preventing the need for developers to rework functionality due to any inaccuracies. I work with both modern iOS/Android stacks and can assist with legacy projects and their maintenance. iOS: - Swift/Objective C - UIKit/SwiftUI - PinLayout/SnapKit - GCD/Operations/AsyncAwait - RxSwift/Combine - Core Data/Realm/GRDB/SQLite - URLSession/Alamofire - StoreKit/StoreKit 2/SwiftyStoreKit - REST/WebSockets/Socket IO/rSocket/gRPC - XCTest/Quick/Nimble - AVFoundation - TestFlight - CocoaPods/SPM - SwiftLint Android: - Kotlin/Java - Jetpack Compose/Android XML + View - Coroutines - RxJava/RxKotlin/Flow - Room/SQLite/Realm - Retrofit/OkHttp - Google Play Billing Library - REST/WebSockets/gRPC - JUnit/Espresso/Mockito - ExoPlayer/Android Media API - Leak Canary - ProGuard Kotlin Multiplatform: - Kotlin Coroutines - Ktor - SQLDelight - Koin/Kodein - Multiplatform Settings - Kotlin Test - Decompose - Compose Multiplatform - Kotlin Serialization - Napier - Moko resources Common: - Firebase services - AppsFlyer - AppHud - CI/CD (Jenkins/TeamCity) My main motivation is to solve my clients' problems, help build their businesses, and provide reliable technical support. 👍

How to Hire Top Mobile App Developers

Building a mobile app is often an ongoing project—one full of frequent updates and new versions to keep up with the ever-changing mobile technology landscape. A successful mobile app takes strategy, marketing savvy, UI/UX experience, and plenty of expertise—all of which culminates in the resume of a top-notch mobile app developer to help you bring it all to life.

So how do you find a mobile app developer? What follows are some tips on how you can find top mobile app developers on Upwork.

How to shortlist mobile app developers

As you’re browsing available mobile app development consultants, it can be helpful to develop a shortlist of the freelancers you may want to interview. You can screen profiles on criteria such as:

  • Mobile ecosystem. You need to decide if you need a specialist for iOS or Android, or a generalist for cross-platform development.
  • Testing experience. Nothing hurts your KPIs like a buggy app on launch day. Look for developers who understand the importance of user testing and test-driven development.
  • Feedback. Check reviews from past clients for glowing testimonials or red flags that can tell you what it’s like to work with a particular mobile app developer.

How to write a mobile app development job post

There are numerous phases of building an app during which you’ll want to engage a mobile app developer: design, coding, APIs and other back-end integrations, and testing. Well-rounded mobile developers have experience with both design aspects, like UI and UX design, and actual programming, whether it’s API integrations or coding in a specific cross-platform software.

Establish your project’s requirements in as much detail as possible to help you budget for hiring a mobile app developer, and to help your developer provide more accurate estimates. For example, if you have preferences about platform or programming languages, include those. If you need an app coded in Swift 3, for example, you’ll want an iOS developer that’s versed in the latest iterations of the language. If you’re creating a mobile app with Xamarin or PhoneGap, you’ll need a pro who knows how to get your app successfully compiled into each native environment. You can get more tips and guidance on how to hire a mobile app developer in this article.

Be sure to include other details like:

  • The targeted platform you’re developing for—iOS, Android, Windows, hybrid, or cross-platform?
  • The scope of the project, which outlines the development and design work to be done
  • Any API integrations or other technical specs the developer should know.
  • Your target audience(s) for the app.
  • Design specifications, including fonts, color pallette, imagery, any logos, and other brand guidelines.
  • The project timeline, including any milestones.
