About

As a Cloud Architect, Site Reliability Engineer, and DevOps professional with over a decade of experience, I have honed my skills in managing high-availability, scalable architectures, and cloud computing environments.

I then progressed through roles at Sabre Holdings, Merchenta, and Schibsted Tech Polska, where I specialized in DevOps, creating self-service platforms, automating operations, and building continuous delivery pipelines.

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. “
