About

I am an IT engineer based in Kraków, Poland, with extensive experience in systems administration, particularly focused on Linux systems. Fluent in both Polish and English, I am open to relocation opportunities. My professional journey has honed my skills in various areas, including cloud engineering, site reliability engineering, and DevOps. I pride myself on my ability to learn quickly, deliver high-quality solutions, and automate processes for efficiency and repeatability. My career has involved roles such as Senior Cloud Engineer at Grand Parade, where I focused on high-level planning and architecture, and Cloud Engineer, where I managed on-prem and AWS cloud systems. I have also worked as a Site Reliability Engineer, ensuring the smooth operation of Big Data processing systems. Throughout my career, I have developed expertise in numerous technologies and tools. I have experience with container management, virtualization, network operations, and various programming and scripting languages. My roles have required me to maintain CI/CD pipelines, manage infrastructure as code, and handle both internal and external customer interactions. I have also been involved in incident management, root cause analysis, and developing monitoring solutions. My technical knowledge spans multiple layers of computer systems, from physical hardware to applications, allowing me to understand and solve complex issues effectively.

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. “
