At Testomat, I support a multi-tenant SaaS and self-hosted enterprise test management platform. I migrated deployments to Kamal 2 and built Terraform and Ansible infrastructure across Hetzner Cloud and Cloudflare, reducing deployment time from over 30 minutes to under 5 minutes.

I’ve delivered DevOps and SRE support across industrial IoT, medical robotics, database tooling, and enterprise CI/CD environments. At Waterleau, I reduced build-agent infrastructure costs from over $400 to under $150 per machine while maintaining performance for an industrial telemetry platform.

At GlobalLogic, I supported releases for a minimally invasive surgical robot, modernized Bamboo pipelines into version-controlled YAML, and helped achieve a 100% successful build rate for ISO-compliant medical releases. Earlier at DevArt, I migrated more than 20 Jenkins jobs to Groovy pipelines and managed internal CI/CD services, virtual machines, containers, and artifact repositories.

I enjoy automating complex deployments, improving infrastructure reliability, and strengthening security through practices such as Linux hardening, full-disk encryption, and bastion host architectures. My toolkit spans Terraform, Ansible, Docker, Kubernetes, Jenkins, Azure DevOps, Linux, cloud platforms, monitoring, and AI engineering tools.
