Cybersecurity Architect | Cloud-Native Defense | AI/ML Security | DevSecOps

With over 23 years of experience in cybersecurity, I specialize in building resilient, zero-trust digital ecosystems across multi-cloud (AWS, Azure, GCP) and Kubernetes (EKS, AKS, GKE) environments. My journey began in network security—firewalls, IDS/IPS—and expanded into Linux/Windows hardening, IAM, and DevSecOps automation using Terraform, GitLab CI/CD, and policy-as-code tools like OPA and Checkov.

Today, my focus is on securing AI/ML adoption through MLSecOps, protecting models from adversarial attacks with tools like Robust Intelligence and Microsoft Counterfit. I integrate AISecOps for threat detection (Darktrace, Microsoft Security Copilot) and automate incident response with forensics-driven workflows (Elastic SIEM, TheHive).

Whether it’s hardening cloud-native stacks, embedding security into CI/CD pipelines, or safeguarding AI systems, I bridge the gap between security and innovation—ensuring defense scales with speed.

Let’s connect and discuss the future of secure, intelligent infrastructure.
