Hi, I'm Greg. I enjoy using math, music, and computers to improve people's lives.

2024 -
Wise (formerly "TransferWise") is one of the largest remittance platforms in the world. As one of the first engineers hired into Wise's Austin office, I lead development of US bank integrations that underpin the "Multi-Currency Account" product. In 2023, I built and shipped the US Interest feature, which offers high-yield interest on USD, GBP, and EUR balances.
2023 -
Built high-throughput data processing systems that validated Stripe's funds flows, and added features to the Risk Reserves microservices and backoffice tools. Volunteered as application reviewer and mock interviewer for YCombinator (Summer 2022 application batch).
2021 -
Led development of the AI infrastructure and datacenter-provisioning software for Habana Labs, a former startup acquired by Intel, to demonstrate the performance and scalability of the Gaudi AI accelerator to external partners. My team's work culminated in a new AWS offering of Gaudi-based EC2 Instances (aka "EC2 DL1 instances") - AWS's first generally-available AI training instances that are not based on GPUs - announced at Andy Jassy's AWS re:Invent 2020 keynote.
2020 -
Returned to Arm - this time, to work in the Research organization - where I built PoCs for, and contributed to, the Internet of Things (IoT) Research Team's intellectual property. Later on, the team expanded into the "AI and Data Services" domains.
2018 -
Employee #60 at Anaconda, the scientific computing company best known for creating the Anaconda Python distribution, the conda package manager, and open-source libraries such as Numba, Dask, and Holoviz. I joined back when the company was still called "Continuum Analytics", led by Travis Oliphant. I consulted on ML / AI / HPC / data-science projects with clients such as:
2015 -
Built electronic design automation (EDA) software tools that enabled Arm's lead architecture partners to verify ISA-compatibility of their customized implementations of the Arm architecture. My team was formerly a software startup, acquired by Arm in mid-2011. Arm was a smaller company (<1k employees) then, led by the venerable Warren East.
2013 -
Two years after AMD went fabless, I joined a DFT team in the Design for Excellence (DFx) group. During the period when AMD's strategic direction was pivoting toward semi-custom design partnerships, I received the "AMD Spotlight Award" for my work on a software tool that standardized how the company reported its fault test-coverage to these external design partners. The flagship customer was Sony for the Playstation 4's Jaguar-based APU.

The software tool worked by equivalence-collapsing all faults that were reported from a variety of internal fault-modeling tools, after crawling the entire design's netlists.

2011 -
Bachelor of Science in Electrical Engineering (BSEE) at Purdue University with a Management minor. Upper-division Finance courses, maymester study abroad in China. Software Engineering internships at Motorola and Blackberry (formerly "Research In Motion, LLC" aka RIM).
