Hire the Best OpenStack Developers in Kharkiv, UA

I help teams deploy, fix, and stabilize Linux-based infrastructure and cloud environments. I work with GCP, Docker, and Ansible to automate deployments, resolve system issues, and make environments reliable and easier to operate. What I can help with: • Fixing broken deployments and unstable systems • Setting up Docker / Docker Compose environments • Automating infrastructure with Ansible • Configuring GCP infrastructure (VMs, networking, storage) • VPN setup, firewall (iptables), and secure networking • Monitoring setup (Prometheus, Grafana) Experience highlights: • Reduced infrastructure setup time from hours to seconds using automation • Supported distributed systems with up to 200 machines (Jetson-based clients) • Built VPN-based infrastructure connecting remote devices to cloud environments • Helped teams integrate applications into stable Docker-based systems I focus on practical results — making systems stable, predictable, and easy to manage.

Every hour of downtime costs your enterprise an average of $540,000. That's not a DevOps metric - that's a board-level problem. I design and operate infrastructure that stays up. My specialty is the full observability and reliability stack: detecting failures before users do, recovering in minutes, not hours, and building the self-healing systems that let your engineering team sleep at night. With $400K+ earned on Upwork, 100% Job Success Score, and 10+ years in DevOps and Site Reliability Engineering, I bring the broadest monitoring stack you'll find in one engineer: Prometheus · Grafana · Datadog · ELK Stack · Zabbix · Sumo Logic - combined with deep Kubernetes and cloud expertise. Typical Problems I Solve → Production incidents are frequent, and MTTR is too high → No observability - issues discovered by users, not monitoring → Need DevOps engineer for high availability infrastructure setup → Kubernetes clusters experiencing performance or reliability issues → Disaster recovery plan missing or untested → AI workloads need reliable, observable infrastructure Proven Client Results ▪️ iLost Platform (Netherlands) → Challenge: EKS performance degrading, CI/CD unstable across Dev/Staging/Production, and OpenSearch causing timeouts. → Solution: EKS rightsizing, CI/CD pipeline optimization, IAM hardening, OpenSearch performance tuning. → Business Impact: Reduced bottlenecks, improved release predictability, and optimized infrastructure costs. ▪️ Qopla Infrastructure → Challenge: Long-term SRE engagement - ongoing reliability, monitoring, and performance needs. → Solution: Continuous SRE operations, incident management, and infrastructure optimization. → Business Impact: 657-hour engagement demonstrating sustained impact. Rate progressed $40/hr → $52/hr based on results. ▪️ GetChecked (Blockchain / Multi-cloud) → Challenge: Multi-cloud infrastructure (AWS + DigitalOcean + bare-metal) with Hyperledger Fabric in a regulated environment. → Solution: Upgraded Hyperledger Fabric, implemented monitoring, backup, DR/BCP, optimized CI/CD pipelines. → Business Impact: Increased system reliability and security in a strict regulatory context. Core SRE Capabilities → DORA metrics: Deployment Frequency, Lead Time, MTTR, Change Failure Rate - measured and improved → Incident Management & On-Call: Runbooks, escalation paths, post-mortems → Disaster Recovery & Business Continuity planning and testing → Zero Trust Security: IAM, RBAC, SELinux, network hardening → High Availability: Multi-AZ, failover, load balancing, autoscaling → AI workload reliability: observability for ML pipelines and LLM infrastructure Stack: AWS · GCP · Kubernetes · Terraform · Ansible · Prometheus · Grafana · ELK Stack · Datadog · Zabbix · Docker · Linux · GitHub Actions · GitLab CI · Incident Response Plan · Disaster Recovery Available during US business hours (EST/PST overlap). Downtime is a solved problem - if you have the right observability. Send an invite and let's audit your reliability posture.

Architecture of small and large applications and their delivery pipelines in the cloud and in onpremise environments is my bread and butter. This includes understanding business needs, providing best available options from different cloud providers, setting up CI/CD pipelines, organizing work of other people on that topic. Being a fan of Devops philosophy I also have broad experience in: * Kubernetes and container ecosystem (CKA certified); * virtualization systems (KVM, Xen) and cloud systems (OpenStack); * Python/Go; * ecosystem of CI/CD toolset (Jenkins, Concourse CI); * configuration management systems (Ansible, Terraform);
