I love simple and clear code so I don't have to explain it. I try to solve the problem in the simplest and fastest way so that the solution does not create new issues in the future. I quickly learn new tools and technologies. I can work remotely. I'm not afraid to ask questions if something is unclear and ask for help if necessary.
I have a bachelor's degree and a master's degree in Computer Science.
I am looking for a friendly team for comfortable work.
I will be glad to communicate or receive feedback from you.
Good day.

My latest role is Lead Software Engineer. I was responsible for developing and maintaining in-house ERP software. In addition to this:
- assisting other development and support team members;
- maintaining and updating existing infrastructure and setting up CI/CD pipeline;
- checking and updating the system and software regularly;
- implementing best practices and coding standards;
- deconstruction of a massive monolithic application into smaller, independent services.
As a result:
- CI/CD was reorganized entirely, the build time was reduced from 40 minutes to 10 minutes, and monthly cost has become lower;
- operating cost lower by ~40% in a year and a half, while many features were released during that time;
- built several independent modules from the existing code base.
Tools and Technologies: Ruby, Ruby on Rails, Sidekiq, RSpec, JavaScript, CoffeeScript, SCSS, AngularJS, Ansible, AWS, PostgreSQL, Redis.
