Position: Senior Front-End Engineer
Category: JavaScript
English level: upper
Years of experience: 6

In a small team of 3-4 FE devs, we developed a new version of the app for an SF startup with Ukrainian roots and successfully released it in about one year time.
In a much bigger company, I improved the visibility of our CI, which helped a team of around 15 FE devs to counter unexpected changes quickly and have a general understanding of CI stability.
I have most experience in front-end stack: react, redux/mobx, next.js for SSR and code splitting, custom SSR and code splitting.
Usually I prefer using typescript for large code bases, but sometimes I still use JS for small scripts. 
I have experience in unit testing with jest and e2e testing with selenium and cypress.
