Hello, I'm Aleksei Aleinikov.
Senior Cloud Platform & Security Engineer at Deutsche Telekom with 12+ years of experience. I built and run Telekom's first production Google Cloud (GCP) platform — multi-region, active-active GKE that sustained FIFA World Cup 2026 peak load and passed an independent DDoS resilience test. Terraform and GitOps, least-privilege IAM and zero trust, Cloud Armor WAF, observability, on-call — owned end to end.

Cloud platform and security engineering on Google Cloud
I help engineering teams in Germany and the wider DACH region run Google Cloud (GCP) in production: secure by default, cost-aware and calm to operate. Three areas where I have delivered measurable results at Deutsche Telekom:
Platform engineering on GCP
Multi-region GKE and Kubernetes, Terraform and GitOps with Argo CD, observability and on-call. The platform that carried Telekom's FIFA World Cup 2026 peak traffic, with cloud spend cut by 40% and SLOs intact.

Least-privilege IAM and Workload Identity Federation, zero trust, VPC Service Controls, Cloud Armor WAF, Security Command Center and hardened CI/CD pipelines. Security that ships with the platform, not after it.
