Cloud backend engineer specializing in Java, Kubernetes, and Azure for reliable production systems.
PolandWhat I'm looking for
I’m a Cloud Backend Engineer (Java) who builds and operates backend systems in production, with experience across full delivery cycles—from developing services to deploying and maintaining them in cloud environments. I’ve worked on mission-critical emergency call handling systems at Motorola Solutions and enterprise commerce platforms at SAP.
I focus on cloud-native infrastructure, data-related systems, and system reliability. At SAP, I’ve operated and optimized Microsoft Azure infrastructure (AKS, managed databases, Blob Storage), implemented safe incremental rollouts with feature flags (LaunchDarkly), and supported production stability on Kubernetes. At Motorola Solutions, I contributed to high availability (99.999% uptime), built CI/CD pipelines with GitHub Actions, and improved release confidence by creating an automated regression test suite with Playwright while strengthening observability using Grafana and Prometheus.
