Position: Back-end Developer
Category: Node.js
English level: intermediate
Years of experience: 2

I refactored monolithic library in modular way, which allows to increase extensibility by providing custom components and more granular configuration by enabling only needed parts
I was working on the decentralized authentication and authorization system. Server side part of the application processes application logic, which defined in the blockchain and regulated by smart-contracts
I am not interested in development which doesn't target "real world" problems, like cryptoexchange, gambling, NFT etc.
