    For twelve years, I work as an iOS Developer. During this time, I have completed many projects. More than half of my projects are client applications for servers. I understand how such applications are arranged. How to receive the data from a service using a REST API. I know how to parse a service response and display it in an app and create offline mode. I have experience with video and audio. I can combine video files, put sound on them, change this sound, add text or image to the resulting video. I worked with video and audio players and recorders. I worked with Maps. I can display places on this map, present custom callouts on it, and show routes from a user location to these places. I also can work with the CoreData framework. I know how to get data from a database on a thread and display it to a user without an interface freezing. In 2017 I decided to create some apps on my own. My friend is a radiologist, and he shared with me his idea about a medicine app. We have created this app and published it to AppStore. You can find it if you search for RadAnatomy and RadAnatomyLite. 50% of the proceeds I transfer to my friend. During the work on this app I put myself in the place of customers and gain the priceless experience how an idea is embodied to the app. I can use Photoshop and Sketch, and you do not need to slice images. Just provide me a file with a design. The rest I will do by myself. I pay attention to pixel-perfect and custom fonts because I respect designer work.

    Hey I'm Eric! I'm a highly skilled iOS developer that's ready to build your iOS app from the ground up. A Little About My Background ------------------------------------ I've built over 20 iOS apps from scratch, launched 9 on the App Store, and sold two of them! The most recent app I built for a client was called Kwiks – a TikTok-styled social media app. I came on board after the app was already in development, and improved video feed performance so dramatically that they offered me a full-time position. I also have a collection of personal apps which you can view by searching "Eric Solberg" on the App Store. The one I'm most proud of is a social networking app called "#Social - Meet people like you". It incorporates a fully fledged in-app messaging feature and implements complex database queries (using Firebase). My most popular app so far ranked in the top 100 "Entertainment - Top Paid" category on the App Store – with over 100,000 organic downloads in less than a year – before it was acquired. What I Offer --------------- - Extensive experience in the iOS app space, including feature ideation, software development, app launch and marketing knowledge, and everything in between. - Perfectionist mindset – I pride myself in exceeding expectations and delivering an excellent product. That means delivering on time, on budget, and with code quality at the forefront. - Fast development – I obsess over your project from start to finish, and can deliver your app in weeks, not months. - Communicative availability – I almost always have my phone on me, so message me anytime! Technical Skills ------------------- • Swift • Xcode • Storyboard and/or UIKit (No SwiftUI) • All Apple Frameworks • Any 3rd-party framework • Firebase Master • UI/UX Design w/ Figma (if needed) Conclusion -------------- Thanks for considering me for your project. If you think we could be a good fit, or even if you just have a couple questions, feel free to reach out. At the very least, I can give you some answers and point you in the right direction. I look forward to speaking with you, - Eric

    I'm an experienced and motivated Senior iOS Developer with an interest in skillfully crafting creative mobile applications and utilities. I understand the importance of creating highly readable, reusable and easily maintainable source code. I am constantly striving to learn new technologies and look to ways to better myself in this rapidly changing industry. I've got an NDA signed with a personal QA assistant. The idea behind - is to have a long-term personal assistant with lower rate helping to ensure the quality, shape the Test Cases, verify the recently developed features on various iOS versions and devices, doing additional manual regression testing, in some cases extra QA automation - to deliver even more reliable and consistent product, decreasing the final cost/dev-time for you, and letting me focus on the challenging things. According to your business processes - you can onboard my assistant too or keep me as a single contact person, or directly inform that I should completely avoid letting my assistant access your project data in any way during negotiation process (Unfortunately once there was a miscommunication about this - and one client got upset that I gave a build to my QA to verify the features developed, though the manager from his side knew about that). My strengths and skills: - 13 years of successful international IOS Development - Firebase (JS Cloud Functions) Development Expert - Computer Science Masters Degree - Project Management & TechLead skills - Software Architecture, REST API design skills - iOS Unit/UI Testing - iOS Continuous Integration (CI) using Jenkins, Fastlane, Xcode Cloud Completed a number of projects, while working at/through: 1) Sloboda-Studio (sloboda-studio.com) 2) NIX Solutions (nixsolutions.com) 3) Search Concepts AG (searchconcepts.ch) 4) TopTal (toptal.com) 5) Upwork 6) imito AG (imito.io) If according to your business goals you'll need web frontend (React JS), backend (Node.js) and Android development to be handled - I can help to manage that through a network of trusted partners.

How to Hire Top Mobile App Developers

From healthcare providers to e-commerce retailers, businesses in a large range of industries benefit from having a mobile application. Commonly known as mobile apps, mobile applications offer users a convenient way to access a company’s services on mobile devices.

Releasing an app can benefit your business in numerous ways, including increasing brand awareness, offering more personalized options, and strengthening customer engagement. However, building a smartphone-ready app also requires the talents of a mobile app developer.

Think of mobile app developers as architects who build a project from the ground up. The right developer can contribute to your project in a number of ways:

  • App design. Developers collaborate with UX/UI designers to turn design layouts and mockups into fully functioning applications.
  • Coding. Mobile app developers write the code needed for your app to function and play a vital role in testing, debugging, and performance optimization.
  • API integration. An app developer can help enhance your app’s user experience by integrating APIs.
  • Future upgrades. Apps are constantly evolving to offer new features or reflect real-time business offerings. Mobile app developers can implement changes needed to keep your app relevant and functional over time.

Throughout this comprehensive guide, you’ll learn what you need to know to hire top mobile app developers who can bring your vision to life.

Mobile app development: An overview 

Understanding which category your app falls into is an important first step to hiring talent with the right development skills. Different types of mobile applications require knowledge of their own programming languages and methodology.

  • Native apps. Native apps are designed to run on a specific operating system like iOS or Android. 
  • iOS native apps. Native apps designed to run on Apple devices are built using a combination of programming languages like Swift or Objective-C and Apple’s Xcode integrated development environment (IDE).
  • Android native apps. Native Android app development usually involves using programming languages like Java or Kotlin combined with the Android Studio IDE.
  • Hybrid apps. Hybrid apps are designed to work on multiple operating systems without needing separate coding. They’re developed using web-based programming languages like HTML, JavaScript, and CSS, then wrapped in the native shells of various operating systems.
  • Cross-platform apps. Cross-platform apps are also designed to run on multiple operating systems but are developed differently. They’re built with frameworks like Flutter or React Native, which enable codebases to work across various operating systems.
  • Web apps. Web applications are apps that users can access through mobile browsers without downloading. They are responsive and commonly built with web development programming languages JavaScript and CSS.

Cost insights: Hiring mobile app developers

The median rates mobile app developers tend to charge on Upwork is between $18–$39 per hour. That said, pricing for app development services can vary widely from one developer or project to the next. Factors that commonly affect mobile app development costs include:

  • Experience level. An accomplished app developer with years of experience will likely charge higher rates.
  • Developer location. A developer based in New York City may charge higher rates than a competitor in a city or town with a lower cost of living.
  • Development type. In general, native apps tend to be more expensive to develop than apps designed to function across multiple operating systems.
  • Project complexity. The more features and functionality an app requires, the pricier it will be to develop.

Timing your mobile app development

Some common reasons you might consider developing a mobile app for your company include:

  • Loyalty reward programs. Integrating a high-quality rewards program into your company’s mobile app can enhance customer loyalty. As customers make purchases, they can track points and redeem rewards right in the app.
  • Additional functionality. Apps can provide customers with access to features like location services, push notifications, or offline access on the go.
  • Personalization. Apps can provide a range of personalization options, such as location-specific offers or customization based on past data usage.
  • Mobile optimization. By offering user interfaces specifically designed for mobile devices, apps can offer a faster, smoother, and more comfortable customer experience for mobile users.

Mobile app development companies vs. freelance developers

App development companies offer access to an entire development team, from UX designers to front-end and back-end developers. The trade-off is that this option tends to be the far more expensive of the two.

Hiring a freelance app developer or building your own freelance mobile app development team can offer more control over your project’s budget, timeline, and creative direction. However, while this approach tends to be the most cost-effective, it may also require more workflow and project oversight.

Understanding the services offered by app development companies

A great app development company can offer all the services you need at each stage of the app development process. Below, we’ll share examples of services commonly offered in the pre-development, development, and post-development stages.

Pre-development

The pre-development stage is when the idea for a mobile app is fleshed out to create a strong foundation. Think of it as building an app blueprint through strategies such as:

  • Concept development. Developers can help you solidify your app idea by mapping out its core functions and features. They’ll then develop a product roadmap or strategy to bring it to life.
  • Market research. A development company can also help you research your target audience and competitors.
  • User experience (UX) design. UX designers will begin by creating a wireframe template of what your app will look like. It will evolve into a wireframe mockup featuring user flows and information architecture.
  • User interface (UI) design. UI designers transform wireframe mockups into fully developed prototypes that integrate design elements such as colors, typography, and branding.

Development

This stage of mobile app development focuses on the construction and optimization of your app. Some of the services app development companies offer at this stage include:

  • Coding. Developers will use a mix of front-end programming languages like HTML or CSS and back-end programming languages like Python or Java to build the app’s core functions.
  • Front-end and back-end integration. Developers will integrate any APIs or SDKs needed to enable communication between your app and any external service providers.
  • Testing and refinement. Perform testing to ensure functionality and usability.

Post-development

Once your app is fully developed and ready to go, great app development companies will guide you through the next steps. These may include services like:

  • App store optimization (ASO). ASO essentially involves increasing your app listing’s visibility in an app store like the Apple App Store or Google Play.
  • Ongoing support. Technical post-development services might involve anything from fixing bugs to integrating new features.
  • Marketing assistance. Some app development companies will even help you outline a marketing plan to promote your new app.

Navigating the legal landscape

When working with a developer, it is important to ensure that all legal bases are covered. Your working relationship should always be formalized with a contract that clearly outlines the expectations of both parties.

Collaboration and communication with your developer

Whether you choose to start by developing a minimum viable product (MVP) or dive right into development, it can be helpful to break down a project into smaller steps. Milestones are checkpoints that allow you to give feedback at each stage of the development process.
