What I'm looking for

I’m looking for a role where I can own packet-level observability for latency-sensitive production, build multi-data-center capture/visibility systems at 99.99% availability, and help teams reach root cause fast with real-time traces and actionable dashboards.

I’m a Network Observability & Packet Infrastructure Engineer with a decade designing and operating packet-capture and TAP-aggregation platforms for latency-sensitive financial systems. I build the multi-data-center visibility layer that trading floors and 24/7 production depend on—capture infrastructure tuned to millisecond resolution and held to 99.99% availability.

Across my roles, I’ve architected packet-broker/TAP-aggregation fabrics, cut mean time to resolution on visibility incidents by 45% by closing tap and coverage gaps, and led packet-capture during latency and packet-loss incidents to produce the traces teams used to reach root cause. I also engineer redundant capture paths and replacement cadences to protect availability, consolidate end-of-life systems to reduce cost, and create dashboards and workflows that help teams diagnose faster with less noise.

Monitoring Engineer

Navy Federal Credit Union

Jan 2021 - Jan 2024 (3 years)

Architected and built out a three–data-center packet-broker and TAP-aggregation fabric carrying up to 100 Gbps of mirrored traffic, establishing one standardized observability layer across all three data centers. Cut mean time to resolution on network-visibility incidents by 45% and maintained the monitoring platform’s 99.99% availability through redundant capture paths and a TAP replacement caden

Operated and tuned ultra-low-latency packet-capture systems (Corvil, Niksun) behind trading-floor analytics at millisecond timestamp resolution. Consolidated and retired end-of-life capture appliances, cutting roughly $100K in license and maintenance cost, and built throughput and retention-monitoring dashboards used across five production environments.

Led the packet-forensics workstream on about three high-severity, trade-impacting incidents per month, isolating root cause for the response team and feeding findings to the incident bridge. Redesigned the alerting strategy to cut chronic false positives by 15%, and produced monthly network utilization and risk reports for capacity planning.
