Looking for senior blockchain developer Hello. I have read your job description and I am very interested in it. I have been working on react.js and react native projects for over 9 years and I have rich experiences and good knowledge. I have used various react.js themes such as material-ui, mdbreact, react-ionic, chakura-ui... and used redux-thunk or saga for state management. Also, I am very familiar with unit tests using Jest and Enzyme. For the backend of these react.js frontend projects, I often use Node.js and some serverless frameworks, such as firebase, and AWS, and sometimes I combined them with Laravel. From my past work, I think I can be the right person for your job. Looking forward to hearing from you. Thank you.
