About

Over the span of more than 12 years, I have immersed myself in the realm of Linux management, development, administration, virtualization, and cloud technologies. My expertise extends to creating and migrating projects into Docker and Kubernetes environments, with a particular focus on micro-service architectures and seamless integration into various cloud platforms. A key facet of my work has been the establishment of fully automated CI/CD pipelines and delivery frameworks across multiple projects, enabling efficient deployment to diverse environments. I have also dedicated significant effort to automation testing, leveraging tailored frameworks to ensure robust testing and optimization across different virtualization setups. Additionally, I possess in-depth proficiency in Linux systems, Docker, Kubernetes, Jenkins, KVM, Puppet, Chef, and Google Cloud Platform. Beyond technical skills, I bring a strong sense of responsibility and self-motivation to every team I collaborate with. My experience includes roles in project management, as well as leading teams and technology initiatives. I thrive in environments where I can apply my technical prowess to drive projects forward, ensuring both innovation and reliability in every aspect of development and deployment.

Best back-end engineers I've ever worked with.

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly.”
