I worked in this company for a very long time, and the main client was Nike. Over the past two years, I completed 6 turnkey projects for Nike. Also there were smaller projects that lasted 2-3 months. Somewhere I was searching and figuring things out, somewhere I did cost optimization, and sometimes I simply acted as an advisor and explained things. The most interesting case at Nike was when there was a project that nobody wanted to take because it required a DevOps person who knew JavaScript. Since nobody was available and the project was on hold, I took it upon myself and spent one month learning JavaScript. They agreed, and we started working on the project. It turned out to be very interesting because I had to test, assist programmers, and perform my DevOps tasks. We delivered the project on time despite the fact that there was a lot of new stuff to handle. We worked together as a team, and it was fun.
