Summary
👤
Senior🎓
Top SchoolWitold Greń is a Lead Cloud Native Engineer and DevOps specialist with over 10 years of hands-on experience designing and operating cloud-native platforms, primarily in AWS and Kubernetes. He drives infrastructure-as-code transformations—migrating CI/CD to ArgoCD/Tekton, standardising pipelines and Terraform/Terragrunt patterns, and introducing local dev clusters to speed E2E testing. Comfortable both as a team lead and an individual contributor, he blends Python automation with pragmatic SRE practices (Prometheus/Thanos, Istio, Vault) to support large production deployments and dynamic environments. Colleagues know him for rapidly onboarding to new tech, sharing knowledge, and inventing small tooling (CLI and Python utilities) that simplify developer workflows. Based in Wrocław, he pairs a strong backend background with a persistent curiosity for automating everything and improving incident readiness.
