• Lead software engineer/designer, and employee #6 at a small software startup developing a software platform for high-performance computing on commodity GPUs and multi-core x86 processors -- yes, HPC on GPUs in 2005-2007 -- a bit too early. Played key roles in many areas, including product definition and design, software development (in C++), test-plan development, product roadmap development, advanced development, process development, patent filings, presentations, pitches, ... For example, designed a dynamic SPMD kernel generator for fused array-level operations and HLSL compiler. Debugged subtle GPU architectural bugs and performance issues. Also made major contributions to the design of the system's runtime and the profiler. Lead overall design of the multi-core product using SSE and multi-threading. Directly managed up to 5 other engineers and successfully guided several projects to completion.

• Technical lead and senior software developer, with a focus on performance. Built an aggressive VLIW compiler backend and profile-guided whole-program link-time optimizer for Transmeta's Efficeon architecture: interprocedural register allocation and scheduling, forwards and backwards dataflow optimizations, ISA-specific optimizations, DWARF debug info remapping, ... Implemented and enhanced optimizations in dynamic binary translator (Code Morphing Software) and VLIW compiler backend. Developed online policies controlling multiple "gears" of translation, adaptive retranslation, and dynamic frequency/voltage scaling. Isolated, characterized, and/or worked around several major frequency-limiting paths in the 90nm generation Efficeon. Implemented and supervised much of the software-tools work for the 3rd-generation Efficeon core, which included new and changed instructions and major new architectural features.
