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:

Thetargeted platform you're developing for—iOS, Android, Windows, hybrid, or cross-platform?
Thescope of the project, which outlines the development and design work to be done
AnyAPI integrations or other technical specs the developer should know.
Yourtarget audience(s) for the app.
Design specifications, including fonts, color pallette, imagery, any logos, and other brand guidelines.
Theproject timeline, including any milestones.
