I am a systems person with a focus on performance and resiliency in the memory/storage hierarchy, primarily in Unix environments. Recently I've been very interested in the design and implementation details of different file systems and storage protocols, both from a software/driver perspective and the hardware they're designed for. I am very interested in hardware-software codesign.I'm currently an HPC Storage Engineer at Hudson River Trading.Before coming to HRT I was a Storage, Backups, and Unix Engineer at Epic (my second stint there).Prior to my second tenure at Epic, I was a High Performance Computing Systems Engineer at the Icahn School of Medicine at Mount Sinai under Professor Patricia Kovatch. I was part of a small team responsible for the administration of the Minerva system: a 2 PFLOPS Intel Xeon-based system with EDR/HDR InfiniBand and IBM Storage Scale (fka Spectrum Scale, fka GPFS) in the form of Lenovo DSS-G.Before my employment at Sinai I spent six years at Epic as a Server Systems Engineer. My role(s) there evolved over time, but broadly my job was to support Caché/IRIS databases running on Unix systems (primarily Linux on x86_64 and IBM AIX on POWER). During that time I worked on storage (primarily block in Fibre Channel SANs) and Unix performance. I also served as the primary contact between Epic and the data protection community at large, developed backup and data protection best practices for Epic customers, and served as the escalation point for related crises.My first career field out of college was acoustic signal processing; first in seismic data at Seismic Ventures LLC, then in the Sonar Development Division of the Advanced Technology Laboratory at the Applied Research Laboratories, a research arm of the University of Texas.I am experienced working with Python, C, Bourne-family shells, and AWK.
