Automation specialist and hunter for the best practices in every part of the project. Mainly focused on building production-ready, secured solutions. I have a good understanding of Agile methodologies as well. I gathered tons of experience working with, setting up and configuring of various continuous integration and continuous deployment systems as well as code quality automation technologies.
