Company: Endeavor Streaming Full-time
Dates: Mar 2019 – Mar 2020 (1 yr 1 mo)
Description:
One of the most fascinating companies that I have. Whole period - like one big challenge :) It's great.
I am alone on this project (Front-end team). Also, there are Android and iOS developers, PM and QAs.
Main responsibilities:
1) Developing new features (UI, logic)
2) Architecture - which library or framework to use. For example, one Client said that he need SEO and we picked up Next.js for that. Another one just wanted an ability to share to social networks and we made an tricky solution (SPA) with Express.js "proxy" with generating of an HTML file.
3) Bug fixing and refactoring - I love refactoring and moving to new technologies.
4) Code review - one of the most important thing in the developer's life.
5) Investigating - there was one feature, developing a video editor in the browser. It was insane in a good way. A lot of articles were read.
6) Reverse engineering - our clients gave us a small project and it was without documentation. We have take most of Endpoint from developer tools (Network tab).
7) New technologies - integration in new team that located at London. Learning new architecture and React-Native basics.
8) I had my first lecture here and it was about React Native and Virtual DOM.
9) English - chatting whole day with our colleagues from London.
10) Interviews - started interviewing.
