Securing the cloud, one packet at a time. Currently building the future of safe MLOps.

I’m a Cloud Infrastructure & Security Engineer who loves solving complex architectural puzzles. Certified in GCP DevOps, Security, and Networking, I spend my time ensuring systems are resilient, automated, and locked down. Right now, my technical playground is at the frontier of MLOps and AI Security—building secure, scalable pipelines for machine learning workloads. On this blog, I write about real-world cloud troubleshooting, infrastructure as code, and the hard-earned lessons of securing modern AI systems. Let’s build things that scale and don’t break.
