Cloud Site Reliability Engineer at Deloitte who improved cross-region application performance by 32%.

United States

Message

At Deloitte, I investigated instability across hybrid cloud application platforms, improving cross-region application performance by 32% and exposing routing and dependency bottlenecks.

I designed resilient connectivity between public cloud services and enterprise data centers using AWS Direct Connect, Azure ExpressRoute, and BGP. That work raised network availability to 99.995%.

I automated infrastructure provisioning and recovery workflows with Terraform, Ansible, and Python, accelerating environment delivery by 65%. I also hardened cloud transit paths with Palo Alto VM-Series firewalls and Panorama, reducing unauthorized network exposure incidents by 40%.

Earlier, I supported hybrid cloud connectivity at Cisco and healthcare network operations at OSF Healthcare. My work included routing, firewalls, network diagnostics, and incident recovery for production services.
