What I'm looking for

I am looking for a senior DevOps/cloud role focused on Kubernetes, infrastructure automation, cloud migrations (Linode/AWS), CI/CD and security-minded teams that value reliability and continuous learning.

I am a seasoned DevOps and cloud engineer with over 20 years in IT, focused on building reliable infrastructure and automating delivery pipelines. I have led on-premises Kubernetes implementations and full migrations to cloud environments.

On recent projects I configured and managed Kubernetes clusters, implemented ArgoCD, GitLab CI pipelines, ELK monitoring, Keycloak, Vault, Terraform and Sops, and migrated complete production systems to cloud servers. I have operated across Linode and AWS and ensured zero-downtime deployments.

I have held leadership roles including CTO and CISO, managed development teams, and delivered e-commerce and enterprise platforms using Python/Django, Nginx, Jenkins and containerized deployments. I pair security-first thinking with practical operational solutions.

I seek to join a results-driven team where I can apply cloud engineering, CI/CD and security expertise to improve stability, scalability and developer velocity while continuing to learn and mentor others.
