Position: Senior front-end developer (React.js)
Category: JavaScript
English level: intermediate
Years of experience: 4

One of the achievements is creating a mobile app. There were many interesting and unexpecting cases, which didn't described in the docs. They were connected with additional libs. Some of them had worked differently on ios, android, emulators and simulators. So, it was an interesting experience to fix, and handle those cases.

Another achievement is my deep investigation in css. I dug deeper and found out how css works under the hood, and how to improve performance of web-page via using css properly. With this investigation I showed a presentation on Font-end community.

And another interesting experience is work connected with increasing web vitals. I adapted js-code, fonts, styles, third-party scripts (their connection to project), different lazy-loadings which React and Next.js provides.

Also, I have created a react-npm-components-package. With its help I shared common methods, contexts, hooks and components between projects.

And the last thing which I'm proud of in this list, but not the least - is my own translation service. This is a universal service which can be used with different projects. User selects a project to translate, selects a page to translate, it can add different languages and then manually add translations for each element of the page in every language which it added before.Service return json file, which can be used with i18n if needed.

For me, the most important things are an amicable team and a cool atmosphere. I expect a hybrid working schedule.
I realize that it's possibly unavailable in your company, but I hope that company can provide a couple of remote working days a week.
