Hello, we have 20 years of experience in design and web development, we have developed several web portals and 2 ICOs for tokens, we also work with many exchanges to obtain data on quotes, prices, etc. we are a team of coders with high skills in PHP, JS, Python, C #, Go, Solidity and we have used web3, the most useful library for connecting blockchain, this library is compatible with PHP, JS, Python, and others We suggest to use nodeJS , the most compatible and efficient version.
We have created crypto charts like tradingview to show and analyze cryptos, support and resistance lines, market depth, and others, now we are working on two NFT Markets and Blockchain Games for a couple of clients on this portal (Freelancer.com), we won the project a few days ago.
Also we can make your App in a hybrid system, based on nodeJS, AngularJS (like IONIC) or ReactJS (like React Native), in other words, with a single development you have the possibility of creating an App for Android, iOS (iPhone, iPad), MacOS and Windows, in addition, it can be viewed on the Web and thus you can upload it to the App Store, Play Store and Windows Store.
The app must be connected to a content manager backend, we can work in Laravel (PHP framework) or Strapi, a headless backend based on nodeJS.
We chat to define the milestones of the project ...
