    Hey, did you 🫵 just search for a flutter developer? Are you having issues with your project built using flutter or do you have an idea that you want to convert into reality? Guess you are at the right place. 🏢 ➡️ Here are some of the key features or important things I can offer to you for your 🚩 problems: • Pixel Perfect UI designs. • Migration from legacy to null safety - 1.XX to (2.XX or above) • Local Caching/Storage using Hive database. • Flutter on Web Platform (Learning SEO in flutter and custom URL routing) • State management solutions - BLoC, GetX, Provider, or Riverpod (Learning MobX). • HTTP Requests i.e. RESTful APIs Integration using HTTP or Dio package. • GraphQL performing Queries and Mutations using GraphQL Flutter Client. • BlueTooth Low Energy using flutter_reactive_ble with ESP32-WROOM-32D and nRF52840 boards. • Google Maps - Live location tracking, places near your position, and much more. (You name it) • AgoraSDK or WebRTC for Audio Video Calling • VoIP SIP using dart_sip_ua package. • Publishing application to App Store using my MacBook. • WebSockets or Firebase Realtime Database for real-time features. • Unit and Integration Tests (Test Driven Design or Domain Driven Design) • Flutter Golden Tests. • CLEAN Architecture (still perfecting it!) ➡️ Some soft qualities that are crucial for clients: 💬 Communication - I have all the communication applications on my mobile to make sure I can get back to my people as quickly as possible, and that way it becomes easier for providing daily updates as well! ❤️ Kind Behaviour - There are often scenarios where contractors try to drain clients out of their last drop and compared to that, I try my best to facilitate everyone and do not charge anything for small tasks, such as providing suggestions or reviewing a few code files. ⚙️ Work Ethic - The main idea is that anyone that comes into contact with me must not go back empty-handed. The least I usually do for clients is provide them with valuable advice when their proposed task is out of my domain. This makes them appreciate me as a human being. ➡️ Here is what others have to say about me: 🌟 “Shahzad is an exceptional character. With his expertise in Flutter, you can completely rely on his development. He is not just a problem solver but a man who assesses the current underlying issues and development, to not just what it takes to solve but to give his views about the development.” - John, Nautilus Network. 🌟 ”His work ethic and honesty are not easy to find” - Berk, BabTech. I offer the best services to make sure the clients are satisfied and that is what makes them appreciate my work ethic and my kindness, thank you!

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.
