Greetings!
I am Artem, a highly skilled Full-Stack JavaScript Developer with expertise in web, gaming, and animation. With a robust 15-year career, including 12 years of proven expertise on UpWork, I have completed 88 projects, all receiving 5-star reviews and maintaining a 100% Job Success Score. As a Top Rated Plus freelancer, I have logged over 10,500 hours, demonstrating my commitment to excellence in developing JavaScript applications compatible with all browser-equipped devices. My portfolio ranges from simple games and single-page mobile applications to sophisticated MMORTS/MMORPG games and complex Rich Internet Applications (RIA) for animators and authors.
My passion lies in tackling intricate and unique challenges in web and mobile development, with a special fondness for gaming and animation projects. My ultimate goal is to establish my own game development studio. I thrive in competitive work environments and am committed to delivering exceptional results.
My professional journey began in 2011, developing casual mobile web games optimized for the then-new iPhone 3GS. Subsequently, I joined Narr8, contributing to an interactive platform for digital books and comics, outperforming Apple's iBooks. Here, I developed 'The Editor,' a tool empowering animators to create content for our platform. Post-Narr8, I initiated MnCreator and worked at KamaGames, focusing on a web app and admin dashboard for advertising management and analytics.
Between 2014 and 2015, I was part of Parallels (later Odin, acquired by Ingram Micro), where I was instrumental in developing a UI Framework for rapid cloud-based product development, including parts of the Plesk panel interface.
I continued my career at UpWork after that, where I worked on a huge list of different projects, from some small games and banners to huge projects for UpWork's Plus Clients.
Key Skills:
- Expert-level in JavaScript (es5 - es2025, whatever version you like), TypeScript, HTML5, CSS3, alongside a wide array of libraries and tools like React.js, Redux, Recoil, Grunt, Gulp, Webpack, Bootstrap, Tailwind, LESS, SASS/SCSS, and Handlebars. And whatever else. Believe me, just name it, and I either worked with it already, or I can handle it.
- Development skills for mobile platforms (Android, iOS, Windows RT, Tizen), with basic knowledge in Java and Swift.
- Proficiency in Node.js backend development, desktop applications (Node-WebKit/nw.js/Electron), mobile applications (PhoneGap/Cordova), and microcontroller software (Espruino, Onion Omega).
- Knowledge of both SQL (MySQL, PostgreSQL, SQLite) and NoSQL databases (MongoDB and its forks).
- Small, but useful experience with GraphQL
- Junior-level skills in Java (Play Framework, Android development), PHP, and Swift (iOS development).
- Basic understanding of C-based languages and ability to code simple things: C, C++, C#, and Objective-C (iOS development).
