Position: Node.js developer
Category: Node.js
English level: intermediate
Years of experience: 1

The most important thing is mathematical formalisation with Category Theory.
After my first work as Node.js Developer (last project is massive parser with Redis-based socket, S3 and MySQL support) my current role is Node.js/Solidity Developer (last project is Decentralized Exchange). But I write the functional way only. My experience path through the Haskell and (accidentally) Python (including course of AI basics). I'd like to find the team that  appreciates FP (my everyday libraries are Ramda, Ramda-Async and Monet.js (to point an execution with IO monad).
I will be happy to find someone who think like me. 

Attention: FP only.
