Krzysztof worked as a Site Reliability Engineer (SRE) on our “Primary 4.0” project in PMI , for more than 3 years. I cooperated with him for the last 2 years. During his tenure, Krzysztof consistently demonstrated exceptional skills, dedication, and a strong commitment to reliability. Krzysztof possesses a deep understanding of cloud infrastructure, particularly on AWS key components. His expertise in managing resources, automating deployments, and optimizing system performance significantly contributed to the success and stability of our project. What truly sets Krzysztof apart is their ability to collaborate effectively with cross-functional teams, including business representatives. He actively participated in incident response, analyzing root causes, and implementing preventive measures. Stability of the system is reconducted to his calm demeanor during critical incidents and complex deployment activities. In addition to technical proficiency, Krzysztof consistently demonstrated a positive attitude and a strong work ethic. He eagerly embraced new challenges, quickly adapting to changes, and continuously improving our processes. One notable achievement was the close-to-zero number of incidents on the project. The project is now a benchmark for similar solution in terms of absence of vulnerabilities . The attention to detail and thoroughness in documentation were invaluable. I wholeheartedly recommend Krzysztof for any SRE role. He is a reliable, proactive, and collaborative team member who consistently delivers results.
