## What I'm looking for

```text
I'm looking to build and secure scalable enterprise, cloud, and telecommunications networks, with opportunities to automate operations, strengthen Zero Trust security, and improve reliability and performance.
```

## About

```text
At T-Mobile, I design BGP and OSPF routing for 5G core infrastructure across 50+ nodes, improving convergence time by 35%. I also automate provisioning with Ansible, Python, and Netmiko, cutting manual configuration time by 70%.

I secure large-scale connectivity through Palo Alto NGFW policies, IPS rules, Zero Trust access controls, and IPSec/SSL VPNs serving 5,000+ remote users. My traffic analysis and capacity-planning work has reduced detection time by 45%, packet loss by 80%, and improved peak-period throughput by 25%.

Previously at Charter Communications and TATA Teleservices, I built MPLS WANs, resilient firewall environments, QoS policies, and cloud connectivity across Azure and AWS. I bring hands-on experience with network automation, vulnerability remediation, routing stability, and highly available enterprise infrastructure.
