In 2017-2018, I worked remotely in a company registered in Wellington, New Zealand, whose founders are US citizens.
In the process of work, I managed to get acquainted with many nuances of work with cryptocurrency exchanges and trade in cryptocurrency.
I was developing code for the application of trade in cryptocurrency on popular crypto exchanges:
• work with crypto-exchange data via WebSocket (protocol version 13) and REST API;
• creating a GUI library with bugfixed and optimized source code.
