    Hello! I have an existing web application that is built with Node and React JS and I need it to be updated to ES6. Particularly the React JS (client) system needs to be reviewed and refactored to use latest best-practices. The update requires code review and suggestions for modifications. I am looking to have these updates done at set intervals and not necessarily in real-time. If this is something you are able to do, please reach out and let me know your skills and experience with this type of project.
