    If you need to resolve some complex iOS-related tasks - you're in the right place! I have experience working both with Swift and Objective-C. Also started creating apps using SwiftUI at 2020. I'm also an expert in the Apple Human Interface Guidelines. As for the architectures, I use the most cutting-edge methodologies such as VIP + Clean Architecture, MVVM+Coordinators, VIPER, MVP. I know how to work on a full-cycle development project since I created different apps from scratch. The most interesting of them were related to: - financial technology + crypto banking; - online shopping solutions; - ARKit + Vision for image recognition and presenting 3d object in AR; - AVFoundation + web sockets for video chats with a remote agent. I also developed an independent SDK in order to be built into different 3rd party apps. For local storage, I usually use Core Data or Realm. For the network layer: Alamofire or native URLSession could be used, it's all up to your preferences and what suits your needs better. In-app purchase with Apple Pay is also a field of my expertise. Feel free to choose different delivery options such as Firebase, Hockey, TestFlight, etc. If you're looking for a developer who really likes his work and is passionate about what he's doing, you've come to the right place! Feel free to contact me anytime you wish. Will be happy to work with you!

    As a Senior developer, I can deliver amazing apps and find opportunities more easily. Practices that set me apart: Automated testing techniques, Automation, Clean Code, Software Design, Architecture Principles and Patterns, Continuous Integration, Continuous Deployment, and so on. As a complete senior developer, I can deliver good software. What gives me speed and quality is following good principles and having a suite of automated Tests that can support a productive, Continuous Integration and Continuous Deployment pipeline. I can release much more often because I know how to use automation. I can integrate my code fast and automatically. I can deploy my app every time I check my code in. So I go much faster because I don't need to manually check every change. And I don't need to go through long days of manual QA. I know how to write good and fast automated Tests. And learn and follow architectural and design principles, object oriented principles, functional principles and so on.

    I’m an iOS developer with more that 5-years’ experience in all stages of software development life cycle, UI/UX and Agile-methodologies. My area of expertise includes developing iOS, watchOS and macOS applications. Analyzing requirements, creating project architecture, creating and testing apps, providing new technologies and frameworks into existing projects. Among years of my experience, I took part in the development of several successful projects, both as a team member and an independent developer. Some of them were written from scratch - others required only maintenance or final touches. And thanks to that I can easily read and understand the code which was written by someone else. I’m a quick learner and easily adapt to new conditions. I focus on team communication, always highly motivated and do not need too much supervision.

I also have a lot of experience with native iOS development (Swift, Objective-C). ✅ Javascript, Typescript, Swift, Objective-C, C, C++ ✅ Redux, Redux Toolkit, MobX, Clean Architecture ✅ Firebase, Node.js, Express, MongoDB, MySQl. ✅ Clean, maintainable code ✅ Continuous Integration ✅ Agile methodology I started my career in mobile app development back in 2014 by first building my own iOS apps and then working for a large company in Russia where I developed complex iOS applications in Objective-C for large and medium sized businesses and government organizations. In 2018 I started freelancing on Upwork and doing projects using Swift. A year later I started doing cross-platform developement using React Native, which I've been doing on this platform on and off since then. I provide secure, scalable, maintainable, and bug-free solutions. I’ve created quite a few apps (mostly enterprise applications for business and government organisations). You can find examples of successful projects in my profile. One of my recent projects was a social network app for people doing sports (trainers and trainees). I developed the app from the ground up. I look forward to working with you. Feel free to contact me for more details.

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.
