Currently, I work at T-Mobile Poland, focusing on Kubernetes development and hardening. Previously, I contributed my expertise at Roche, mBank S.A., and NVT Sp. z o.o., where I handled tasks such as Ansible automation, Gitlab management, Docker usage, Kubernetes consulting, and the creation of VM auto-deployment solutions. My career has also involved significant roles in server and network administration, task automation, and the integration of OpenStack with Kubernetes. I have a solid background in managing various server environments, automating processes, and implementing monitoring systems using tools like Grafana and Prometheus. I hold a degree in Electropower Engineering from the Military University of Technology in Warsaw and have completed various certifications and trainings, including AWS Architect and Oracle Database SQL Expert. My technical skills encompass Linux administration, Kubernetes, Java application servers, scripting languages like Python and Bash, and CI/CD methodologies. Additionally, I am passionate about containerization and network solutions, constantly seeking to deepen my knowledge in these areas. My future goals include obtaining further certifications such as the CKA and potentially exploring management studies related to Big Data. I am eager to work in an international environment where I can utilize my language skills and technical expertise to drive innovative IT solutions.

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. “
