Senior escalation and performance engineer with deep experience across distributed systems, virtualization platforms, and GPU- accelerated environments. Focused on low-level Linux debugging, performance diagnostics, observability, and tooling/telemetry development (Python/bash). I approach problems as a big-picture thinker, focused on whole system analysis and understanding how interactions across hardware, virtualization layers, and distributed components produce real-world behavior. Over the past decade I've specialized in resolving the most complex, multi-layer technical issues within enterprise environments - bridging compute, storage, hypervisors, networking, and largescale virtualized stacks. I work at the hardware/software boundary to uncover root causes, stabilize systems, and enable durable fixes. Recent work includes: * GPU performance debugging (NVIDIA) and advanced instrumentation * Distributed systems analysis and cross-team technical investigations
