About
I am a passionate DevOps Engineer and Systems Architect with over 15 years of experience in designing, building, and maintaining highly available and scalable infrastructure.

Throughout my career, I've successfully led infrastructure transformations, migrating legacy systems to modern cloud-native architectures on AWS and Kubernetes. I thrive in complex environments, focusing on automation, security, and cost-optimization.
