  • Jun 2022 - Present

  Cybersecurity company, focusing on securing Android ecosystem via mobile Operating System, developer tools, and apps, driven by ML and AI. Built for Governments, Enterprises, and individuals. I joined the company after the previous DevOps team left. I got the system "as is" (given the almost complete lack of documentation). I ensured the smooth functioning of all systems (including production), created a small team that completely covers the DevOps/IT areas. I have re-engineered all systems, created a set of basic manuals for all major services, implemented a new set of tools (Jira, Confluence, GitHub etc.) for the efficient operation of all teams, and am completing the migration from Amazon to Google cloud. I also created a Kubernetes environment(GKE cluster etc.) for a new product of the company. Now under my responsibility - support, design and creation of production/staging/development environments on premise/Data Centers(Europe, USA, Asia)/AWS/GCP. Technological stack: Java, NodeJS, Android, Ubuntu, Debian, CentOS, VMWare/Proxmox, Atlassian(Jira, Confluence), Jenkins/GitHub/GitLab, Ansible, Artifactory, Logz.io, Site24x7, micro services, Kubernetes(GKE)/Docker, AWS/GCP, Gerrit/Git.
