## Availability (open to hire)

Aleksei is looking for a permanent, full-time senior role in Germany and the DACH region — platform engineering or cloud security engineering. He is also available for contract and consulting engagements. Core areas:

- **Legacy-to-Cloud Migration & Modernization** — risk-controlled migration of legacy/on-prem systems to GCP, AWS, or Azure (containerization, re-platforming, Terraform IaC, zero-downtime cutover)
- **Cloud & DevSecOps Architecture** — multi-cloud, cloud-native platform design, Kubernetes/GKE, GitOps, Infrastructure as Code
- **Cloud Security Architecture** — CISSP-aligned security design, Zero Trust, Cloud Armor WAF, IAM hardening, Policy-as-Code, threat modeling, security audits
- **AI/ML Engineering** — LLM fine-tuning, RAG, agentic AI, MLOps, GPU inference, AI governance (EU AI Act)
- **FinOps / Cloud Cost Optimization** — architecture reviews to reduce spend and improve reliability
- **Technical Writing & Architecture Documentation** — engineering articles, runbooks, executive presentations

### 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.
- **Work authorization**: 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.
- **Ideal roles**: Senior/Staff Cloud Platform Engineer, Cloud Security Engineer, Platform/DevSecOps Engineer — onsite, hybrid, or remote 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.
