What I'm looking for

I seek challenging DevOps/platform roles where I can build resilient CI/CD pipelines, automate infrastructure, improve security, mentor teams and expand cloud-native expertise.

I am a Senior DevOps consultant with extensive experience designing and operating CI/CD pipelines, cloud platforms and infrastructure automation across AWS, Azure, OpenStack and Kubernetes ecosystems.

I have led DevOps teams, introduced security and reliability improvements, and delivered tooling and automation for development, QA and support—reducing manual work and stabilizing production environments.

My career spans consulting and in-house roles in IT and telecom, where I implemented IaC (Ansible, Terraform, SaltStack), container platforms (Docker, Kubernetes, ArgoCD, Helm) and monitoring solutions (Grafana, Prometheus, Loki) to support scalable, hardened deployments.
