    I have been freelancing for two years, and have a 100% client satisfaction rate over a variety of complex projects. My speciality is MIDI and audio with native code, but I am also adept at generic Android client work, and can churn out screens at an impressive rate! I have written the most fully featured and music notation app for Android singlehandedly, as well as Forex trading tools, a Midi to MP3 converter, a band management system, forum browsing software and a discussion game for a charity. I have 14 years commercial experience in C/Linux. I adhere to sound software design principals (SOLID, TDD, Clean Architecture). I can learn any new framework extremely quickly, and am up-to-date with the latest Android components and patterns (Jetpack, MVVM, MVI).

    HOW CAN I HELP YOU Hello, I'm Emir. I develop mobile application solutions to business owners/entreprenuers. I help you with developing cross-platform, modern and native-looking mobile applications && all sorts of more stuff. When you hire me, you'll be left with clean, modular and non-repeating code (if project requirements allow so). Most developers on Upwork will bring smelly code to the table which at first seems managable but as the project scales it'll be harder and harder to maintain the codebase let alone develop new features. I'll try my best to not be that developer. WHAT TO EXPECT - Receive replies to messages throughout the day. - Voice/Videos conferences periodically, managing the business and strategic problems. - Weekly/Monthly periodic updates and working demos/PoC's - 7/24 support and in-depth conversations about your products and how to improve them.

    I have been developing apps for mobile devices since 2012. In that time I have collected a number of tools and skills to improve both development speed and quality in the apps I create. My passion is improving user experience - developing apps which users will enjoy interacting with. This includes UI design, animated content, polished transitions, etc. With many apps requiring online services I am also well versed in various server-side technologies for user authentication, databases, analytics, and much more. Previous clients have been impressed by my excellent communication skills and ability to work consistently with little to no supervision. Please take a look at my portfolio and client reviews to see previous work and evidence of my work ethic.

How to Hire Top Android Developers

How to hire Android developers

Android is the world’s most popular mobile operating system (OS). Whether you’re trying to create an Android app from scratch, or port an existing iOS app to Android, an Android developer can help bring your mobile project to life.

So how do you find an Android developer? What follows are some tips for finding top Android developers on Upwork.

What is Android development?

Android developers use the Java programming language, the Android SDK, and other tools to develop apps for smartphones, tablets, and other mobile devices running the Android OS.

Here’s a quick overview of the skills you should look for in Android development freelancers:

  • Native app development through the Android SDK
  • Solid grasp of UI/UX design fundamentals
  • APIs such as REST and SOAP
  • Version control systems such as Git
  • Project management systems such as Jira
  • Cross-platform mobile app development frameworks such as React Native

Android development consultants help businesses create powerful mobile apps that can compete in the Google Play Store.

How to shortlist Android development freelancers

As you’re browsing available Android 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:

  • Expertise. If your app requires expertise in GPU programming, game design, or accelerometer control, you’ll want to find a specialist.
  • Past work. Good code is well documented, some developers showcase their past projects or provide presentations highlighting their achievements on their profiles.
  • Feedback. If you’re wondering what it’s like to work with a particular Android developer, past reviews are a good place to look.

Why do you want to hire Android developers?

The trick to finding top Android developers is to identify your needs. Is this app intended to be used as a secure user account portal? Will the app need to incorporate any unique features, such as scanning documents and reading text? The cost of your project will depend largely on your scope of work, and the specific skills needed to bring your project to life.

How to write an effective Android developer job post

With a clear picture of your ideal Android developer in mind, it’s time to write that job post. Aim to provide enough detail for a freelancer to know if they’re the right fit for the project.

An effective Android developer job post should include:

  • Scope of work: From user chat rooms to user authentication list all the deliverables you’ll need.
  • Project length: Your job post should indicate whether this is a shorter or larger project.
  • Background: Translate your Android developer needs into a candidate profile. If you prefer experience working with certain industries, software, or marketing channels, mention this here.
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.
