About Me

Cloud and Network Engineer with 10+ years of experience in cloud engineering, networking, Python development, and AI technologies.

I bring expertise across Azure, AWS, GCP, Kubernetes, Docker, Terraform, and enterprise networking protocols including BGP, OSPF, and SD-WAN. Currently at Microsoft as an Azure Tech Support Engineer SE, I specialize in complex hybrid cloud networking solutions for Fortune 500 clients.

My career has taken me from Cisco TAC to global-scale network engineering at Schlumberger, nationwide infrastructure projects at Telefonica, and now cutting-edge cloud + AI work at Microsoft. I'm a 3x Microsoft Global Hackathon winner and passionate about leveraging AI to transform operations.
