You are looking at an experienced freelance React developer that will help you build amazing, blazing fast web applications.
Depending on complexity of project requirements, coding will be done in Javascript or Typescript. Buyer can specify preference before project start.
Standard and Premium packages can include responsive designs provided by CSS frameworks such as Bulma.io or Bootstrap.
The Premium package includes app routing capabilities provided by React-Router, state management provided by Redux and any back end integration with server or database. If you don't have any, I recommend Firebase by Google.
If you have any other specific requirements, feel free to contact me for free consultation. I'm looking for my next big challenge. If you have it, I'd like to hear from you.
