Hi, my name is Kamil Lelonek
Platform Engineer · DevOps · Cloud Infrastructure · SRE · Elixir Developer
15+ years building internal developer platforms and cloud infrastructure on AWS and Kubernetes. I design golden paths and self-service tooling that let engineering teams ship faster, with GitOps, observability, and DevSecOps built in.
About Me
Platform engineering, cloud infrastructure, and DevOps at scale.
My Journey
Hello! I'm Kamil Lelonek, a Platform Engineer and technical leader with IT experience since 2010. My background spans platform engineering, cloud infrastructure and architecture, backend development, and team leadership. I hold a Master of Engineering in Computer Science and Management from Wroclaw University of Science and Technology in Poland.
My Expertise
I build internal developer platforms, distributed systems, and data pipelines on AWS and Kubernetes. My focus is developer experience: golden paths and self-service infrastructure that reduce cognitive load and cut delivery time. I treat the platform as a product, with GitOps, DevSecOps guardrails, and observability built in, plus AIOps for predictive monitoring.
Leadership Philosophy
I lead engineering teams through technical project management, architecture design, and delivery. I align business goals with infrastructure planning, deployment orchestration, and incident response. Clear communication, realistic milestones, and removing blockers help teams ship secure, scalable, automated systems.
