Elena Grahovac

Software Development Engineer (Backend)

Summary

I am an experienced backend engineer with software design interests and leadership skills. I love to automate manual job. I am passionate about site reliability engineering topics. I believe that my personal purpose is to help other developers to improve and simplify their processes and daily routines and be successful.

Personally, I think that people are the most important and I'm looking for an employer who shares my thoughts.

In my free time, I like to contribute to open source and communities. I believe that it is great to share people's knowledge and experience and I like to write blog posts and prepare talks and workshops about the technical things I know.
