Summary
🤩
Rockstar🎓
Top SchoolMarcin Kubica is a Platform Engineer with 11 years’ experience building reliable, automated infrastructure and developer platforms across fintech, broadcast, and security domains from London. He combines hands-on cloud-native engineering (GCP, GKE, Terraform, Kubernetes) with deep systems and automation roots—Ansible, Bash, Python and CI/CD—to create independent, performant teams and scalable pipelines. Marcin has driven ground-up platform work at Deblock and EngineerBetter, contributed Golang validation and tests to the widely used External Secrets Operator, and built terraform-driven deployments for critical Cloud Foundry components. He is comfortable moving between low-level sysadmin tasks and platform architecture, having led data-centre builds, OS migrations and SOC infrastructure engineering. Known for pairing and mentoring, he often accelerates junior engineers while delivering production-grade automation. Outside core tooling he blends pragmatic R&D with production discipline, so proofs-of-concept routinely become robust, repeatable systems.
