Summary

After my studies and extensive training in IT infrastructure, DevOps and databases, I have been working successfully as a freelancer in Germany since 2012. As an experienced DevOps and cloud expert with 6 years of AWS and Azure experience, I bring deep knowledge and technical skills. My expertise includes automating deployments, scaling and monitoring cloud infrastructures, especially with tools like Ansible, Terraform and Jenkins. I have 6 years of experience with AWS, Azure, monitoring with Grafana, CI/CD, Kubernetes and Terraform. In addition, as a full-stack developer I have gained strong experience with Next.js, Go, JavaScript, MongoDB and Python. These skills complement my DevOps profile and let me work effectively on both frontend and backend. I work well in cross-functional teams and can explain complex technical concepts clearly. I have extensive experience implementing security best practices and migrating applications to the cloud. My ability to solve complex technical problems and find creative solutions makes me a strong candidate for any DevOps, cloud or full-stack development role.
