Andrii S.

As a Senior DevOps Engineer with over 5 years of hands-on experience, I specialize in building scalable, secure, and highly automated cloud infrastructure for fast-moving startups and enterprise environments. My expertise bridges the gap between development and operations—ensuring efficient, reliable software delivery with a strong focus on automation, monitoring, and cloud-native architecture. Cloud-first & Automation-driven: I design and manage infrastructure in AWS, GCP, and Azure, using best practices in Infrastructure as Code (Terraform, CloudFormation) and Configuration Management (Ansible, Puppet). CI/CD & DevOps Pipelines: Whether it's GitLab CI/CD, Jenkins, or AWS CodePipeline, I streamline software delivery with robust, repeatable pipelines and implement containerized workflows with Docker and Kubernetes. Monitoring & Reliability: Proactive system visibility is my priority. I deploy and fine-tune monitoring stacks like Prometheus + Grafana, CloudWatch, and Datadog, and set up alerting systems to catch issues before they impact users. Problem Solver, Not Just a Tool User: I don’t just know tools—I solve problems. From automating repetitive processes to securing critical infrastructure and minimizing downtime, I bring value where it counts most. Strong Linux Foundation: With years of Linux system administration (RHEL, Ubuntu, Debian), I build infrastructure that’s not only automated—but resilient and secure from the ground up. Let's work together to optimize your infrastructure, automate your deployments, and scale with confidence.
