About

I am a Certified AWS Solution Architect with several years of cloud experience, specializing in designing and implementing secure infrastructure on both GCP and AWS platforms. Throughout my career, I have successfully led multiple projects from inception to production, ensuring robust and scalable architectures that meet stringent product requirements. At ClearScale, I built multi-account AWS organizations, developed secure CI/CD pipelines using GitHub Actions with self-hosted runners, and created comprehensive infrastructure roadmaps. I also prepared statements of work and designed AWS infrastructure, emphasizing the AWS Well-Architected Framework. My previous roles include serving as a Lead Platform Engineer at Clim8 and Fondy, where I focused on AWS and GCP cloud security, IAM management, and Kubernetes operations. Additionally, I have a strong background in DevOps and platform security, gained from my tenure at Tradeshift and Grid Dynamics. I am proficient in various technologies and tools, including Red Hat, Python, Terraform, Kubernetes, and GitOps. My education includes a Master’s degree from Jagielonian University and a Bachelor’s degree from AGH University of Science and Technology, both in Applied Computer Science. Fluent in English, Polish, and German, I enjoy skiing, motorbiking, cycling, running, and swimming in my free time.

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. “
