Lead end-end system test effort for Class-of-Service, Firewall features in Juniper's new platform/OS including automation
Mentored and trained junior team members in the team
Lead scale and performance measurement for multicast feature in Qfabric platform from PDT
Developed test strategy for scaling tests covering control/data plane and HA for L3 features supported in the platform
Uncovered many design limitations/scale related issues during the execution phase and assisted in debugging end-end which includes control plane as well as packet forwarding.
Performed several RFC tests to measure latencies in different platforms and provide comparison matrix in different modes of switching
