Work experience

DevOps engineer

from 01.2022 to 08.2024 (2 years 8 months)
Olearis, Харків (IT)

I designed and optimized CI/CD pipelines (GitLab CI) for mobile and backend applications, automating build, testing, and deployment processes. I implemented unit and integration tests as well as automated rollbacks, reducing manual intervention during release cycles. I built multicloud infrastructure across AWS, GCP, and DigitalOcean with a focus on scalability, high availability, and cost efficiency. I deployed containerized applications using Docker and Kubernetes (EKS, GKE) and worked with services such as EC2, S3, RDS, VPC, Cloud Run, Cloud SQL, and DigitalOcean Spaces. I implemented monitoring and observability using Prometheus, Grafana, and the ELK Stack. I designed alerting rules, dashboards, and log pipelines to improve incident visibility and reduce downtime. I strengthened infrastructure security by optimizing IAM policies, automating SSL/TLS, and performing regular configuration audits.

System administrator

from 06.2020 to 02.2022 (1 year 9 months)
Triolan, Харків (Телекомунікації, зв'язок)

System Administrator | ISP Triolan (2020–2022)
Managed and maintained the core network infrastructure of a major
national ISP serving over 100,000 subscribers. Administered and
configured D-Link routers and switches, ensuring stable routing,
VLAN segmentation, QoS, and network security across multiple
distribution nodes. Performed daily configuration and
troubleshooting using CLI commands such as show ip interface, show
running-config, vlan database, spanning-tree, ping, and traceroute,
ensuring optimal connectivity and minimal latency.
Implemented and supported dynamic routing protocols (OSPF, RIP,
BGP) and managed network segmentation using VLANs (802.1Q) for
traffic isolation and performance optimization. Monitored and
diagnosed network health using tools like SNMP, MRTG, Wireshark,
tcpdump, and traceroute to detect packet loss, latency, and routing
anomalies.Administered Linux-based servers handling DNS, DHCP,
NAT, and firewall (iptables), ensuring reliable IP address distribution
and traffic routing. Managed user authentication and bandwidth
control using PPPoE and RADIUS systems. Applied preventive
maintenance, firmware updates, and link redundancy strategies to
achieve 99.9% uptime and improve fault tolerance across the network
backbone.
