Wrote an automated, future-proof back-up system using protobufs and amazon.com's S3.

Consulted for Prometheus Research by pure telecommute. Delivered a 1-month-allotted, one-off web app in 3 weeks and turned it into an integral part of their flagship product. Architected/implemented their web-based data collection services for use in both online and offline modes. Wrote extensions for Firefox.

Developed a digital mash-up machine. The Firefox-based app, tested on Linux and Win32, runs in desktop or server mode and provides a browser-based drag-and-drop (Web 2.0) user interface to instruct the C++ back-end. The machine can automate, personalize, and combine data entry/extraction from disparate sinks/sources (web pages, streaming media, databases, proprietary apps, etc) and output to mobile phone(s), cell(s) in an Excel spreadsheet, specific locations in a Word doc, a browser, printer(s), database(s), etc. The design allows for massive scalability using distributed computers.

Post-Secondary Education

PhD In Chemical Engineering The University Of Calgary 1994 - 1998

Created a predictive, two-dimensional, time-averaged hydrodynamic model for a circulating fluidized bed (CFB) riser operating in the fast fluidization regime with downward flow of gas and solids near the wall. Modification of the elaborate two-dimensional model allowed for its coupling with kinetic reaction equations to form a general, tractable CFB riser reactor model. The culmination of the research manifested itself in the form of a fully object-oriented, multi-threaded simulator written in C++. The simulator importd an MFC graphical user interface supporting drag-and-drop process flow diagram construction, novel object persistence design, and generic flash calculations.

Substantial projects stemming from course work: design and implementation of a generic, multi-purpose chemical plant simulator, Gibbs energy minimization of a modified Claus plant reaction furnace, simulation of transpiration cooling of an insulated cylinder, steam reforming of methane, and isentropic discharge of an ideal gas from a duct.

Achieved a GPA of 3.85/4.0. Awarded John S. Poyen Scholarship & DB Robinson and Associates Travel Grant.
