What I'm looking for

I seek roles focusing on secure, scalable cloud and network infrastructure, automation, and observability where I can lead modernization, enforce governance, and accelerate engineering velocity.

I am a results-driven Network, Cloud & Infrastructure Engineer with 4+ years leading enterprise-scale network, security, and systems operations across 600+ distributed sites. I combine hands-on expertise in cloud migrations (AWS/Azure), systems administration (Linux/Windows), and infrastructure automation (Terraform, Ansible, Vagrant) to deliver secure, cost-optimized platforms.

I have led major projects including multi-vendor SD-WAN rollouts, data center WAN integrations, and ATM security upgrades, achieving measurable outcomes such as 99.9% uptime, 20% latency reduction, and a 95% reduction in vulnerabilities. I emphasize observability, governance (PCI DSS, CIS Controls), and practical DevOps/SRE practices to help teams move faster and safer.
