    Hi all, I'm a Senior React.JS/React Native developer with 10+ years’ experience During the last four years, I primarily focus on React Native and React.JS projects, have experience in back-end development using Node.JS and Firebase. At the beginning of my career I have been working with Angular and Apache Cordova. In my work, I have used the following tools: typescript, redux, redux-saga, redux-persist, react-navigation, graphQL, google APIs, OAuth 2.0, underscore.js, ramda, rx.js, etc. Also, I have prepared different tasks and education projects for my work team and coworkers, that’s why I think I have a high level of responsibility and organization skills. I will be glad to help you to get your project to the next level.
