Profile

I am an accomplished Cloud and DevOps Engineer with over 20 years of experience in delivering production-grade solutions across cloud-native, containerized, and automated environments. As a freelance consultant, I partner with clients to provide highly technical solutions, ranging from coding and infrastructure automation to deployment and optimization.

With a strong background in software development, I approach infrastructure challenges with a programmer's mindset. I focus on writing clean, maintainable code and building robust pipelines and platforms that facilitate fast and safe delivery. I thrive in hands-on roles where I can deliver end-to-end solutions, tackle complex technical problems, and continuously improve systems through automation and tooling.

My work is grounded in Platform Engineering and DevSecOps principles. I am committed to enhancing the developer experience and reducing cognitive load through reusable patterns and scalable solutions.

Dedicated to continuous learning, I keep my skills sharp through platforms like LinkedIn Learning, Udacity, Coursera and KodeKloud.
