    Hello! 🙋‍♂️ I am Nazar, and I have been developing native Android apps for over two years now. No matter how challenging the task presented may seem, I'll never classify it as impossible. With that said, if I start something, I always do all I can to finish it. If you are looking for a solution from a dedicated, professional, and respectful freelancer, your search is over. 🖥 Most of the projects I've completed were Android applications made from scratch by me. That provided me with enough expertise in the field to complete tasks of ranging difficulty, as I am familiar with all the stages of development. ⭐️ The fields that I specialize in: ❇️ Android app development (Java, Kotlin) ❇️ XML UI Design ❇️ Android Architecture Components (Room, ViewModel, LiveData, Lifecycle) ❇️ Android Jetpack Architecture Components (View Binding, Data Binding, Navigation Component) ❇️ Dependency Injection (Dagger Hilt) ❇️ API communication within Android apps (Square Retrofit2) ❇️ Firebase: Realtime Database, Storage, Authentication ⭐️ Additional Skills: 🎉 Git VCS 🎉 Figma 🎉 Adobe Photoshop 🎉 SQLite 👨‍💻 What makes me the best suitable candidate for you? 🔔 Healthy and efficient communication. I am always open to changes and listen carefully to listed requirements by my clients. I strive to be respectful and provide the best quality of work for my customers. 😌 Diligence. No matter the difficulty, I will do my best to take on new challenges. My motto is that everything is possible and achievable. All that's needed is the right amount of time and passion for it. 💎 Quality. For me, the quality of work I complete is my top priority. If I can't ensure the best quality of work, I won't start working on the task. 💵 No satisfaction - no pay. You only pay for the work if you are 100% satisfied with the delivered solution. 🧑‍🎓 Self-development. My goal in life is to learn continuously. Consequently, it applies to computer sciences. The market is constantly growing and evolving, and I am willing to learn and develop my skills along with it. 🏄‍♂️ In my free time, I enjoy taking beautiful photos, capturing the world around us in details that hide in plain sight. In these times, being constrained to our seats, I try to get as much exercise as possible. I strive to keep my body in good shape and live a healthy lifestyle. Also, as my passion, I like exploring the world of music, deconstructing the songs to the basic levels, and searching for meanings behind them. In case my portfolio sparks your interest in working with me, feel free to contact me and discuss our future business. 💪

    Hi, you would love to work with me, a friendly developer who is responsive (I reply my clients in minutes) with a solid foundation in modern front-end technologies and a passion for crafting intuitive mobile experiences, I am excited about the opportunity to contribute to your project’s success. ⚡Bonus disclaimer: I also do native iOS/Android development , so any chance you want to migrate to another tech stack or need to dive deep to native platform you can count on me. Here is how I can help you with my 6-year experience in React Native development: • I've worked on 2 projects that has more than millions users. • Producing responsive screens and visual components from design materials, then hook them up with backend endpoints. • Integrating application logic with 3rd-party services or SDKs. • Configuring app distribution using Diawi (Test), TestFlight (Staging) and Apple Developer (Production). Optionally, I configure a mobile CI system that automates app deployment using Fastlane over Bitrise (Cloud) or Jenkins (On-premise). • Last but not least, I know Apple and Google submissions guidelines in-and-out, tips and tricks on how to by-pass to get your app approved faster. • These daunting experiences should be familiar to me, who has spent the last 6 years working with various modern mobile app frameworks, and finally in love with React Native. My portfolio contains entirely of React Native projects, which is my most favorite framework in my career as a mobile frontend developer. Since 2017, I've been heavily using React Native to build dozens of business-grade mobile apps that leverage social media systems, e- commerce, payments, multi language chat/messaging portal, map-based/location-based/anything-based.... Yet I still feel intriguing about your innovate product and want to explore more if have a chance. I live in ICT timezone (UTC+7) but I am pretty flexible to adjust to different time zones (AU/ EU/ US markets) to accommodate client's needs. On top of it, I always keep my clients updated via daily reports so that they easily keep track of progress. I am available via e-mails and in messengers for anything urgent. Regard Gio Na Le

    Hello! I'm Lucas. I am a highly experienced software developer who specializes in app and mobile game development, and I have been building apps, games, websites, and other software for over 15 years. I graduated with honors from the University of California: Santa Cruz with a degree in Computer Science (with a focus in game design). Upon graduating, I worked as an engineer for Intel for several years. After that, I decided to become an independent developer and have managed my own app development company for the past 9 years. I have developed and released several popular apps and games of my own design for Android and iOS, and have worked on countless projects on a freelance basis. These projects have ranged from small bug fixes/optimizations, to prototype designs of new games, apps and utilities, to fully functional apps for small studios and large corporations alike. Though I have focused expertise in mobile app and game developments, I am also quite skilled in related fields such as UI/UX design, web development, backend programming, and technical art creation (Adobe Photoshop/Illustrator/etc.). I am constantly learning new skills and work hard to keep my knowledge up to date with new frameworks, platforms, tools, and best practices. Don't waste your money on a bloated production team, and don't risk your dream project with an inexperienced or inattentive freelancer. Regardless of the needs of your project, big or small- prototype or production-ready, I'm your dev. Let's build it!

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.
