React.js/React native developer with 5+ years of commercial experience

I have 5+ years of strong experience in Frontend and React Native development with good knowledge of ES5 and higher. During this time I gained in-depth understanding of React Native and React.js frameworks. I’ve developed numerous cross-platform apps for iOS and Android so I definitely possess necessary commercial experience and knowledge in order to provide you with an instrumental solution. Besides, I’m advanced with Redux, redux-saga, responsive design with HTML/CSS, implementing animations, etc. I also worked with PHP Laravel so I have insights on backend technologies, including databases which helps me productively work with backend developers and APIs. As to my personal skills, I'm a great team player and can easily perform in a fast-paced agile environment. I'm also a good communicator and problem solver. Finally, I'm always looking for opportunities for self-development. Do you require to extend existing team? Would you like me to pick-up where the previous developer left? Are you planning a project from scratch? Please shoot me a message with project details, I’ll be glad to assist you with any request!
