I'm a Mobile App developer with 5+ years of experience in Native & Hybrid app development. My top skills: - Native app(java, kotlin, Swift, Objective C) - Hybrid app(React Native, Ionic, Cordova) - Video streaming and Image processing(OpenCV, XMPP, WebRTC) - Third Party API manipulation. - Front End (React.js/Redux, vue.js , HTML5, CSS3, Bootstrap) - Back End (Node.js, Laravel, CodeIgniter) - C, C++ Programming It is very important for me to build a long-term relationship with clients, so I'm primarily looking for long term projects.
