Personal Projects

http://Zwibbler.com

A vector graphics application implemented entirely in Javascript (9000

LoC).

Extensive use of HTML5 features, including Canvas, LocalStorage.

The server renders images using the Google V8 Javascript engine, with

Canvas and database access implemented using my own C++ objects.

websequencediagrams.com

Created a web-based tool in C++ to draw sequence diagrams from a text

description.

Learned how to sell to enterprise, run a company, and provide customer

service. Sales are growing, and customers include many well-known

technology and communication companies.

Learned to write portable applications that will run on many different

versions of Linux as well as Windows.

QBASIC Javascript

A limited implementation of QBASIC in Javascript (7500 lines of code).

Implemented complete parsing engine, from regular expressions to

Earley parsing to static type analysis.

http://Rhymebrain.com

Researched dozens of machine learning papers to find a technique for

automatically extracting word pronunciation from English text, using the

EM algorithm.

Implemented entirely in C++, most algorithms are O(number of letters).

The rhyme engine starts from scratch for each request, loads the 12 MB

database, and completes in 30 ms. The entire website is currently

running on a 1GHz Acer Aspire One netbook.

Various windows apps

Various Windows applications made using the WIN32 C API.

Photowipe: Image processing removes objects from photos. Just paint

them black and hit go.

Banshee Screamer Alarm (1999): 100 lines of C++ code for the Alarm,

29,900 for the skin framework that allows switching on the fly and uses

3 inappropriate design patterns.

Shark Ticker. A desktop stock ticker.

Work Experience

Research in Motion

Senior Software Developer, Office of the CTO. 2011 to 2012

. As part of a small research think tank, we held frequent discussions about the future

of technology,

while we created prototypes to learn about them and evangelize to others in the

organization.

. I used Python/HTML5/Riak to create machine learning and cloud storage technology

demonstrations.

Team Lead, EDGE/LTE Firmware. 2003 to 2011

.

Manager and lead developer of a team responsible for writing and maintaining the

central

components of a cellular protocol stack, including EDGE RLC/MAC, RR, UMA, EDGE L1

control,

and LTE L1 control layers. Can quote sections of the cellular communications standards

3GPP

44.018, 44.060, 44.318, and 44.008 from memory.

. Seen as an expert who can be counted on to solve critical problems under pressure.

. Helped create logging tools to diagnose problems from the field.

. Wrote CSN.1 and ASN.1(PER) compilers at home for fun to aid development.

Microsoft CorporationSoftware Design Engineer, Networking and Transports. Spring 2002.

. Designed and implemented a Layered Service Provider that allows IPv4-mapped

communication

over IPv6 sockets.

Soma NetworksSoftware Developer, Telephony Group. Fall 2001.

. Modified real-time audio filters to support new encodings using Java and C.

. Improved reliability of product and regression test suite.

Quack.com (AOLbyPhone)

Software Developer, R&D. Spring 2000, Winter 2001.

. Aided management in understanding complex technical issues. Interacted with industry

partners to

get answers when needed.

. Created prototype projects to quickly answer questions like, How can we do this with

available

technologies? .

. Adapted vendor-supplied speech recognition engine to reside on a separate server and

process

concurrent requests via HTTP and XML.

. Designed and implemented an object-oriented hardware abstraction layer to simplify

Dialogic

telephony APIs.

Corel CorporationSoftware Developer, Text Engines. Winter and Fall 1999.

. Learned to quickly assess the impact of changes to legacy code in an extremely large

project.

. Proposed, specified, and implemented several new features in CorelDRAW.

o Colour Theory: Automatically finding N colours which appear maximally different from

each-

other.

o Natural Language Processing: Automatically finding word pronunciation (Later created

http://rhymebrain.com).

o Static analysis of binary executables (techniques for creating or detecting malware).

o Automatic type inference for compiler optimization.

o Wavelet edge detection for image processing.

. University of Waterloo, Ontario. Sept. 1998 April 2003.
