    I've been working as an iOS Developer for 9 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.

    You're looking for an app, I want to help. Maybe it's a great idea you have, or an extension of your online presence. Maybe you're a startup that needs a proof of concept, or you have an existing app that needs some updates or feature changes. These are some of the many ways I can provide value for you. Take a look at some of my apps on the app store at appsbyandrew.com I’ve been building iOS apps professionally for over five years, and recreationally for almost ten. I have a good eye for UI design and can make apps that look and function as well or better than the most popular on the App Store. I've paid close attention to the patterns and trends of apps that do well and understand what it takes for an app to be effective and successful. One of the earliest apps I created was a grades and information app for a local high school. The app quickly acquired over 20,000 users (other schools within the district even started using it) and it made over $7,000 in revenue for the school to buy supplies with. A more recent app I built was a social media app similar to Instagram. It was fully featured and highly complex to build, including all of the features one would expect to see in a modern social media app like real-time messaging, likes, comments, photo uploads and editing, push notifications, trending and featured screens, customizable profiles, and many complex user interface elements. I was the sole developer on this project and built it entirely from start to launch by myself. After launch this app was downloaded by thousands of users within the first week alone, and became very active almost immediately.

    Freelance iOS developer working in Swift and Objective-C. 6 years experience building for iOS. 3 years experience building and updating Android applications in Java. I love my work as a mobile developer, and I welcome the opportunity to bring my enthusiasm and skills to your next project! My emphasis is on developing data-driven applications for small businesses largely or internal use, however I have also developed and published a number of different types of apps. Several of my published projects are listed below for your review. I have worked both developing projects from scratch as well as taking over existing codebases in order to add features and/or ui modifications. Frameworks I am accustomed to working with include UIKit, CoreData, CoreBluetooth, CoreMotion, CoreLocation, AutoLayout, SpriteKit, as well as RESTful apis (reading, parsing, displaying and posting), Notifications, Firebase, Git, Jira, Trello, Zeplin, and Marvel. As a business owner, I am familiar with working on deadline, and I bring professionalism, communication, punctuality, and great attention to detail to your projects. I believe in collaborative, test-driven development, and my preference is to get a prototype in your hands as quickly as possible so that we are continually ensuring that the app being built is the app you intend. Prior to becoming a full-time developer I accumulated 13 years experience as a productive small business owner, including designing, developing, maintaining and marketing an ecommerce website. As such I have a practical understanding of needs from the client side, which I believe enhances my ability to be an asset and contributor to your project.

    I have been working professionally as an iOS Developer for over 7 years now. Through those years I have become advanced in developing full feature apps in both Objective-C and swift. Many of the apps I have worked on are very high profile with names you would recognize. Although I can easily develop all aspects of an iOS app from the networking layer to the front end, I am particularly good at mobile analytics and front end development. I am by far strongest in iOS development, but I also am well versed in a variety of other frameworks and languages. These include: Wordpress Ruby on Rails PHP JQuery AngularJS. As a final note, I was a creative person before I became a developer. As such, I have an eye for design. I find that most clients appreciate this.

    I specialize in building secure and scalable mobile applications for businesses of all sizes. I can work as part of your team, or do all work by myself. I can do both frontend (React Native) and backend (Node.js, Express, MongoDB). 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.

    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.

How to Hire Top Mobile App Developers
 




How to hire 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.
    •
