Hello, I am currently developing a web application for cryptcurrency tax calculation. Part of the functionality of this web application is that the user can import data (transaction history, withdrawals, deposits) automatically via API from different cryptocurrency exchanges. This project requires only back end coding to fetch transactions from these exchanges with API. All front end is already done. Some exchanges are also working already. Framework used is Laravel. More information about data and exchanges can be found here: [login to view URL] List of exchanges to be implemented: - Bitfinex - Coinbase - Coinbase Pro - Kraken - Kucoin - Poloniex - BitMex - Bibox - Huobi Global - Bitstamp - Gemini This will be an ongoing project, and in the future we can add more exchanges to the list. When you message me, please let me know your experience with APIs and cryptocurrency exchanges. It is very important that the developer I hire do have the necessary skills and experience to do this project. Thank you!

My past jobs and 16 years of experience make me a very prominent candidate to help you over a successful project. Hence I'm new to the platform I am ready to work on fix rate projects. Be assured that from design to deployment everything will be taken care of. As there are no many details that have been shared about your project I am proposing an arbitrary price. I have already worked on the crypto exchange API's. I have a working POC which i can show you while you open the chat. I'll be happy to share my past work matching your requirements because the list is too long. A good chat will help us more. Thank you, Anand P.
