Hello! My name is Kamil Lelonek, a DevOps Engineer and Technical Team Leader with experience in IT since 2010. My commercial background covers mobile & backend development, cloud infrastructure & architecture, and team leadership & project management. I hold a Master of Engineering degree in Computer Science and Management from Wroclaw University of Science and Technology in Poland.
I specialize in building distributed platforms, real-time systems, and big-data pipelines. My expertise includes cloud architecture, CI/CD automation, and infrastructure reliability. I apply AIOps for predictive monitoring, embed DevSecOps practices such as automated scanning and compliance enforcement, and use platform engineering with GitOps and internal developer tools to streamline delivery.
I lead engineering teams with emphasis on technical project management, architecture design, and delivery execution. My leadership centers on aligning business requirements with infrastructure planning, deployment orchestration, and incident management. I focus on clear communication, setting realistic milestones, and removing blockers so teams can deliver secure, scalable, and automated systems.
