Position: Senior backend developer
Category: Node.js
English level: upper
Years of experience: 5

Always ready to learn something new: new libs, new technologies, new languages.
Started my career as a front-end developer (React.js) switched to the back-end after 1 year (Node.js), and after 4 years started working as a fullstack dev. On the front-end part worked with React + Redux (+ Thunk/Saga/Redux-toolkit) most of time, but had 1 project on Mobx. On the back-end worked with Node.js frameworks: Express (1 small project), Adonis.js (3 big projects), Nest.js (2 projects). Worked with postgresql majority of time, but have experience with DynamoDB (AWS version of mongo) on 1 project. Always writing tests on back-end. Almost all of the projects, mentioned above, was started by me, and I finished them also, so I can see what problems may cause different decisions. Also, have experience with dev-ops work, were responsible for server part (Ubuntu virtual machine on Azure) for 3 projects, where set up deploy, back-ups, different envs for FE and BE. Also, have experience with Blockchain development (Hyperledged Composer, which now is deprecated unfortunately).
If we are talking about development cycle, I'm ready to be part of every part from planning to supporting stage.
