About Andrew P.

I’m an Escalation Engineer and Tanium subject matter expert focused on advanced troubleshooting and root cause analysis for enterprise endpoint performance and security issues. My role sits at the intersection of engineering, operations, and customer success, helping large organizations maintain stable, secure, and high-performing environments at scale.I lead high-visibility escalations for Fortune 500 companies, government agencies, financial institutions, and global brands, supporting reliability across hundreds of thousands of endpoints.What I Do BestTanium Platform ExpertiseDeep experience with Tanium architecture, deployment, and optimization. I serve as a primary escalation point for Asset, Discover, Engage, and Performance modules, resolving complex issues that impact enterprise-scale environments.Systems Performance Analysis (Windows & Linux)I approach performance problems through a systems-thinking lens, focusing on how CPU scheduling, memory management, I/O paths, and concurrency interact.On Windows, I analyze performance at the OS and kernel level using event-driven tracing and execution-flow analysis. I focus on how threads move through the scheduler, where they block, and how latency accumulates across CPU, memory, disk, and filter-driver paths. Tools that support this work include ETW, Windows Performance Analyzer (WPA), PerfView, Procmon, and WinDbg for crash-dump and kernel analysis.On Linux, I apply a workload-centric and latency-focused approach to understand system behavior under real conditions. I analyze on-CPU versus off-CPU time, syscall paths, scheduling delays, and I/O wait to identify where time is actually spent. Tools include perf for CPU profiling, strace for syscall and latency analysis, and supporting kernel metrics.Executive Communication & Framework DesignTrusted to lead high-stakes customer calls, translate deep technical findings into executive-level narratives, and design diagnostic frameworks that improve investigation speed and consistency across escalation teams.What Sets Me ApartTrusted advisor on mission-critical Tanium escalationsStrong at turning complex technical data into clear, actionable insightsCreator of investigation frameworks adopted across teams

Experience

1. Escalation Engineer - Visibility

   Tanium

   Jan 2025 — Present · Bellevue, WA, US

   I lead deep-dive investigations into complex enterprise endpoint performance and security challenges across large-scale environments. As an Escalation Engineer, I own advanced diagnostics and root cause analysis across Asset, Discover, Engage, Performance, and OS-level investigations — driving reliability and visibility for mission-critical customer deployments.My work focuses on understanding system behavior end to end, combining system forensics, code-level troubleshooting, and targeted diagnostics to identify root causes, accelerate resolution, and deliver durable fixes. I analyze execution paths, thread behavior, and latency across CPU scheduling, memory management, disk I/O, and driver stacks to uncover issues such as antivirus interference, minifilter delays, DLL and handle contention, registry and COM misconfigurations, WMI activity, and crash or memory corruption.On Windows, I perform trace-driven and kernel-level analysis to understand how workloads move through the operating system and where time is lost. On Linux, I apply workload- and latency-focused analysis to distinguish on-CPU versus off-CPU time, scheduling delays, and I/O wait across both containerized and bare-metal environments.I regularly debug Tanium packages and scripts, analyze source behavior to identify subtle execution differences, and build custom diagnostics to replicate environments, validate fixes, and shorten investigation cycles — bridging product behavior with OS internals to guide long-term improvements.I lead high-visibility escalations for Fortune 500 enterprises, government agencies, and major financial institutions, supporting stability across hundreds of thousands of endpoints. Beyond technical execution, I translate complex findings into executive-ready narratives, mentor peers in advanced analysis techniques, and develop diagnostic frameworks that improve investigation speed and consistency across the escalation organization.
