Software Engineer

Microsoft

August 2023 – Present Seattle Area, WA
Software engineer working on the Microsoft AI accelerator (MAIA) SDK development with a focus on improving performance and developer experience. I work in a cross-disciplinary team with AI frameworks engineers and hardware designers to build abstractions for programmability, performance, and portability. Other responsibilities involve pathfinding and hardware-software co-design.
 
 
 
 
 

Hardware Engineer

Microsoft

August 2018 – July 2023 Seattle Area, WA

Lead architect for a soft vector processor implemented as an FPGA overlay for a deep learning accelerator. Worked across the stack, including ISA, architecture, microarchitecture design, RTL development, testing and validation, software optimization.

Also worked on a pathfinding team for the Microsoft Cobalt SoCs.

 
 
 
 
 

Research Assistant

Carnegie Mellon University

May 2013 – August 2013 Pittsburgh, PA
My work focussed on improving methods for inference in Bayesian probabilistic graphical models, specifically, grid-like Markov random fields. I explored a variety of improvements to inference algorithms from the point of view of hardware implementation.
 
 
 
 
 

Research Assistant

Ecole de Technologie Superieure

May 2011 – July 2011 Montreal, QC
My work involved designing and prototyping a multi-touch user interface for network visualization. Most of my work focussed on designing new and innovative gestures for network layout manipulation. I also conducted experiments to develop empirical laws predicting speed and accuracy of pointing and tossing gestures using a mouse.
