Static Compilation
Implement several hundred built-in functions for C/C++, COBOL, and PL/I.
Migrated compiler to 64-bit z/OS
Helped creation of new C/C++ compiler of zLinux.
JIT Compilation
Researched and implemented several unique optimizations.
Analyzed performance of benchmarks to create optimization plan.
Great amounts of experience in trace jit debugging, including interop with virtual machine.
In charge of build team's build and test system.
Interfaceware, Developer, Toronto ON 2008
Added skinning system to web site to support low-colour systems such as VNC over a slow connection.
Deployed and tested a virtualized Oracle RAC 10g system over 2 VMs.
Pioneered use of jQuery to speed up cross-platform development.
Computer Skills
Experience in performance analysis, investigation, and development using tools like Intel VTune, OProfile, and VPA.
Strong Linux and Unix command line experience along with Vim.
Programming Languages
Full Proficiency
C, C++, Java, x86 Assembly (including SSE), System 390 Assembly

Demonstrates resourcefulness and strong work ethic through the creation of an independent co-owned company.
Creative and analytical abilities, able to multitask and handle varied assignments.
Ability to work either independently or in a team situation, in a workplace environment or remotely.
Written my own raytracer from scratch that supports spheres, planes, and boxes being solved directly. Planes, spheres, boxes, tori, tori with different distance metrics, and metaballs, along with domain repetition, translations, and rotation are supported as signed distance fields. Basic bounding volume heirarchies using spheres are also supported. Path tracing support is being worked on and has some preliminary results. SSE is used heavily throughout the vector, colour, and intersection code. OpenMP is also used for parallelization support.
Yoyoing for more than 15 years. Competed in the Canadian National Return Top championship 3 years running, with a best placement of 7th overall in 2010. Judging the 2012 competition. Performed at the Chinese Night Market Toronto 2 years running. Member of both the YoYoToronto club and the University of Toronto YoYo Club.
Programming Languages
Member of the Toronto Lisp Users Group and Fundamentals of New Computing mailing lists. Following several programming language theory blogs including Lambda the Ultimate, Axis of Eval, and Playing With Pointers. Always have at least 5 different language environments installed at once with some nice cross pollination, like using Scheme paradigms in MATLAB.
Text-Mode Demo Competition
Twice taken part in the Text-Mode Demo Competition with self-written demos. One included real-time raytracing, and the other included a scrath-built rasterizer capable of several thousand triangles per frame. Great experience was gained with both graphics work and the combination of graphics, music, and design.
