Sony Scaria

Associate Principal Network Engineer

Executive Summary

A strategic and versatile Associate Principal Network Engineer with over 15 years of experience architecting, implementing, and optimizing large-scale global infrastructures. I possess a deep technical foundation in Core Routing & Switching, having managed mission-critical networks supporting tens of thousands of devices for global leaders in the manufacturing, banking, and ITES sectors.

My career is defined by a balanced mastery of traditional backbone networking and modern hybrid-cloud ecosystems. I lead high-stakes infrastructure transformations—including Data Center consolidations, SDN transitions, and global network migrations—ensuring that enterprise operations remain resilient, secure, and highly performant. While I hold advanced expertise in MS Azure and F5 Application Delivery, I operate as a holistic architect, orchestrating the foundational routing, switching, and security layers that power the modern distributed enterprise.
