We are a tiny dev team compared to competition. All of us are working hard to build the best platform possible. The number of projects that we have in the works is growing so talent is always welcome ( careers@bitfinex.com ) Let's build an exchange technology for the P2P web!!https://twitter.com/bitfinex/status/1057243152283787269 …

Thx for sharing. That's really quite small. C++ with MySQL for the matching engine, node with Mongo for web-backend? (I know, I'm super curious) How are the devs spread over the stack? Majority C++ or node?
Matching engine is not relying on MySQL, it would be too slow. We use ZMQ queues and it's all in memory. Most Node.js few C++ for hardcore stuff.

Not relying on, but as a persisting layer? pure memory (without any persistence) sounds risky. Of course the matching itself would need everything in RAM for speed. So matching engine also (partly) node.js?

Indeed we have a persisting layer. Don't make me spoiler everything ;)

I always find the discrepancy between dev-count in core stuff (c++) and "frontend" (like node) quite odd. Its same the same over here and it totally works out, just interesting...

Indeed. Finding good C++ devs is also more difficult, at least in my experience. EOSFinex and matching engine are relying on C++ for example. We use a lot FFI also both in Node and in Ruby to improve our routes under the hood
