• Improved NAT scale by 100x over kernel iptables NAT by implementing a DPDK-based NAT pipeline.

• Developed and maintained NAT features on the P4-based programmable 7170 series switch, including a feature to handle unicast-to-multicast NAT and vice-versa, dynamic NAT connection logging and packet counters, NAT connection limit improvements, and an IPv6 firewall that imitates full-cone NAT filtering.

• Addressed customer technical needs by developing custom features and maintaining communication channels to provide ongoing support during integration into deployments.

• Saved $3000-$4000 in onboarding costs per new engineering hire by streamlining the onboarding process to get new hires up-to-speed and productive up to a week sooner

• Reduced customer maintenance costs by implementing a Linux filesystem drift detection warning system in Python

• Implemented IS-IS route leaking feature in C

• Worked as a team of 8 interns and researchers to develop an integrated, multipurpose, virtualized network monitoring system for traffic monitoring, threat detection, active threat mitigation, and performance analysis

• Developed test architecture for measuring and analyzing throughput discrepancies between physical and virtual network testbeds to improve future simulation accuracy and replicability

• Implemented a multipath variant of Dijkstra’s routing algorithm that finds a set of multiple best routes

• Built a Ryu SDN controller that manages a network with this multipath Dijkstra’s algorithm, and tested it with the Mininet network simulator to validate correctness
