Why Entrust Your Delivery to Me?

I have dedicated countless hours to high-impact projects across Europe and Central Africa, immersing myself in diverse tools, environments, and cloud platforms. This extensive exposure has sharpened my expertise and transformed me into a highly effective DevOps professional.

I am deeply passionate about automation and bring advanced proficiency in OpenShift, Kubernetes, GitLab CI/CD, Jenkins, and Azure DevOps—ensuring efficient and reliable delivery pipelines. My track record includes deploying on-premises OpenShift and Kubernetes clusters on VMware, architecting cloud solutions on Azure and AWS, and executing seamless production workload migrations.

With a strong focus on infrastructure as code (IaC), I excel at building scalable, secure, and cost-effective systems that drive tangible results.
