Build multi-platform p2p exchange. Me and my team implement variety of cryptocurrencies and networks, including btc, xmr, eth, ton, usdt and trc & eth networks. Multiple platforms such as: web, mobile and telegram bot, allow the user to choose what he's comfortable with and login in his bitpapa account, every single platforms have exact same functional. Platform don't use any third party solutions, all calculations and business logic happening on the local self hosted servers.

In additional I've set up internal secure company network, for production servers, that are spread all over the world.

For 2 years of work my team rewrote 94% of old code and wrote a whole new direction. Growth for all time of my work in telegram bot was 2200% (thank’s crypto boom) and a quarter of users went to website. As far as I know the company continues to grow with a new owner.
