## Professional Summary

Aleksei Aleinikov is a senior cloud platform and security engineer with 12+ years of hands-on experience across enterprise-scale production systems. He is a **Google Cloud Ambassador for Infrastructure (2026)**, a **Google Cloud Security Champion**, and a **Google Product Expert** — part of a small, Google-selected group recognized for deep Google Cloud expertise and community impact. His core is secure cloud platform engineering — deep GCP/Kubernetes platform work paired with CISSP-aligned cloud security (Zero Trust, DevSecOps) — with additional, production-proven depth in AI/ML infrastructure and technical authorship.

He currently works at T-Digital by Deutsche Telekom, where he owns and operates a production multi-region, multi-cluster Google Kubernetes Engine (GKE) platform serving multiple product teams in mission-critical environments. His work spans the full lifecycle: from architecture design and threat modeling, through Terraform IaC provisioning and Argo CD GitOps delivery, to Zero Trust security hardening (Cloud Armor WAF, Binary Authorization, Policy-as-Code), full observability (OpenTelemetry, Prometheus/Grafana), and incident response — all at enterprise scale with strict SLO compliance.

He is a prolific open-source contributor with production-grade projects spanning post-quantum encrypted networking (ClawSec), AI prompt security (Prompt Seal), quantitative cyber risk modeling (Human Risk Graph), and experimental network protocol design (Open-IPv8-Lab) — each with real adoption, CI/CD pipelines, and published packages.

He is a published book author. His titles include "Prompting Python Data Visualization: Design, Build, and Automate Visual Insights with Python and AI" (Orange Education / Orange AVA, 2026, ISBN 978-9349887992, 401 pages) and "Code Your Own Path" (a practical guide for aspiring developers). He runs an independent engineering blog at https://www.alekseialeinikov.com/en/blog — his primary, canonical publication — with in-depth articles on cloud architecture, security hardening, Go systems programming, Kubernetes, AI compliance, and DevSecOps best practices, and has also published on Medium (Level Up Coding, DataDrivenInvestor) reaching thousands of readers. He has won multiple AI hackathons at Deutsche Telekom, demonstrating rapid prototyping and AI delivery skills.

### Market Fit — Germany & DACH

- **Bilingual delivery (EN + DE)**: writes and maintains in-depth technical content in both English and German — a rare differentiator for German-speaking engineering teams. Every blog article ships in both languages, and all role-tailored CV pages are available in EN and DE.
- **Work authorization & relocation**: based in the EU (Greece) with an EU residence permit and full authorization to work in the EU. Actively relocating to Germany & the DACH region within 1–3 months (standard notice period); open to the EU Blue Card route and employer relocation support. Onsite, hybrid, or remote.
- **Ideal roles**: Senior/Staff Cloud Platform Engineer, Cloud Security Engineer, Platform/DevSecOps Engineer — across Germany, Austria, and Switzerland (Berlin, Munich, and the wider DACH region).
- **Mission**: help German and DACH engineering teams adopt Google Cloud with confidence — a market where GCP is under-represented versus AWS/Azure. Employed at Deutsche Telekom, driving real-world GCP adoption at carrier scale.
