👋

Hello, I'm Kevin. I'm a Staff Platform Engineer & Cloud Architect with 6+ years of experience building and operating large-scale cloud infrastructure across AWS, GCP, and Azure. Certified AWS Solutions Architect Professional. Passionate about Kubernetes, DevOps automation, observability, IoT, and AI engineering.

About me

After graduating with a degree in Electrical Engineering from Universidad Nacional de Colombia, I built a 6+ year career in Cloud and DevOps Engineering. I’ve designed, automated, and operated large-scale infrastructure across AWS, GCP, Azure, and Oracle Cloud. I’ve worked at IBM, Oracle, Banco de Bogotá, Globant, and Simetrik, and I’m currently a Staff Software Engineer / Platform at Visa.

I hold multiple certifications including AWS Solutions Architect Professional and six Oracle Cloud certifications. My expertise spans Kubernetes, Terraform, CI/CD automation, observability, and SRE practices. I also build full-stack web applications and have a passion for IoT, AI agents, cybersecurity, and bug hunting.

When I’m not coding, I enjoy playing video games, watching movies, and spending time with my dog. I also enjoy learning new things, especially history and philosophy, and I’m currently learning to play the guitar.
