I am an engineer, doing DevOps, helping developers implement their services and being responsible for the reliability of their services. I specialize in web applications written in Java.
My responsibilities: - Managing and optimizing high-load infrastructure, ensuring its scalability and fault tolerance. - Increasing the level of system observability to quickly identify and prevent problems. - Infrastructure automation using IaC and configuring CI/CD processes. - Cross-functional interaction with teams to comply with SLA. - On-call and prompt incident resolution. Technologies: TeamCity, Kubernetes, Helm, Docker, Argo CD, Git, Linux, Bash, Python, PostgreSQL, Prometheus, Grafana, Ansible, Puppet, Bitbucket, Nginx, Molecule, Git.
• Eliminated manual build processes by developing an automation robot (GitLab CI/pywinauto), reclaiming an estimated 33% of the development team's time for feature development instead of overhead tasks. • Accelerated new feature time-to-market by 42% through CI/CD pipeline optimization, slashing C++ application build time from 4+ hours to 18 minutes (a 14x improvement). • Developed a Python-based service for automated release analysis, which reduced production incident triage time by 23%. • Reduced operational costs by 18% by migrating the CI/CD system from TeamCity to GitLab CI. Technologies: GitLab, TeamCity, Kubernetes, Helm, Docker, Argo CD, Git, Red Hat Linux, Windows Server, SonarQube, make, cmake, Conan, Bash, PowerShell, Python, PostgreSQL, AWX, Prometheus, Grafana, Nexus, pywinauto, Git .
• Made the services the reliability leader in the department by guaranteeing 99.98% SLA and minimizing downtime, which protected key business processes. • Mitigated a critical cybersecurity risk with a projected financial impact of over $5M, by remediating 5 critical vulnerabilities ahead of internal audit deadlines. • Executed a project migration to a monorepo, reducing the remediation time for critical dependency vulnerabilities from 3 days to 1 hour (-98.6%). • Increased development team productivity by ~22% by optimizing the CI/CD pipeline and reducing build and deployment times by 53%. • Implemented dedicated test environments (Dev and Test), which reduced the time spent on finding and locating critical bugs by 61%. Technologies: Jenkins, OpenShift, Docker, Hashicorp Vault, Bitbucket, Git, RHEL, Dynatrace, SonarQube, Checkmarx, Istio, Maven, NPM, Nginx, Nexus, Bash, Groovy, Python, Apache Kafka, EFK, PostgreSQL, SQL, Keycloak, Kubernetes, Git .
- Automated CI/CD processes and managed deployments across all environments (development, staging, production), including production rollouts. - Optimized pipeline configurations and implemented features to reduce Time-to-Market (T2M). - Managed secrets and remediated security vulnerabilities in the infrastructure. - Provided consulting, mentoring, and onboarding for new team members. - Improved application reliability and participated in incident response and resolution. - Documented DevOps/SRE processes and best practices in Confluence.
