About Yacine

🔐 Hybrid Cloud Security Architect

I’m a Hybrid Cloud Security Architect with 6+ years of hands-on experience designing and securing mission‑critical IT infrastructures. I focus on building highly secure, scalable environments that power SaaS and AI/ML solutions, ensuring organizations can innovate with confidence.

💡 What I Do Best:

✅ Hybrid Cloud Architecture: Designing and optimizing infrastructures across AWS, Azure, and on‑premises platforms (Nutanix HCI, VMware, Hyper‑V).

✅ Security & Compliance: Implementing ISO 27001‑aligned policies and controls, and PCI DSS requirements to safeguard hybrid clouds, servers, and user endpoints.

✅ Scalable SaaS & AI/ML Environments: Creating resilient architectures that support rapid growth while maintaining enterprise‑grade security.

✅ End‑to‑End Lifecycle Management: Driving projects from initial design through deployment, monitoring, and continuous improvement.

🚀 My Approach: I bridge the gap between innovation and security. By combining deep technical expertise with a strong compliance mindset, I help organizations modernize their IT ecosystem without compromising trust, performance, or resilience.
