Back-end Ruby, Ruby on Rails Senior developer

I have been working in the IT industry since 2016. During this time I have been involved in a number of commercial software projects, business applications with Web technologies; HighLoad systems. I have designed and implemented backend systems for many projects. Collaborate easily with co-workers and work well independently. Perform effectively despite sudden deadlines and changing priorities. Hard worker, quick learner, and ability to assume responsibility. Willing to jump into develop "outside the box" solutions.
