- Designed, tested, and validated cloud-based, secure network infrastructure for Prisma Access across AWS and GCP.
- Engineered and validated IPv6 routing, BGP routing, IPSec tunnels, NAT/NPTv6, and SD-WAN traffic flows at production scale.
- Tested, validate and automated PAN-OS security features, including App-ID, User-ID, Data Loss Prevention (DLP), Threat Prevention, and SSL decryption within Prisma Access.
- Lead the traffic mirroring feature for security monitoring, compliance, and analytics pipelines.
- Built Python-based network automation tools for tunnel provisioning, route validation, App-ID/User-ID policy verification, and traffic inspection.
- Performed packet-level debugging of: Routing failures, tunnel drops, firewall dataplane issues, asymmetric traffic and NAT failures, App-ID misclassification, and User-ID mapping issues.
- Scaled firewall and access infrastructure to support over 1 million user logins, validating User-ID redistribution and authentication behavior under extreme load.
- Partnered with SRE and Infrastructure teams to validate: Production upgrades, network and security configuration rollouts, high availability, failover, and zero downtime traffic cutovers.
- Integrated network and security validation into CI/CD pipelines (Git + Jenkins).
- Delivered a 60% reduction in manual network and security validation through automation-first testing.
- Worked closely with Product Management to validate: Feature design feasibility, security policy enforcement using App-ID, User-ID, and DLP, network interoperability, and multi-cloud behavior consistency.
