I have a long history as an IT professional, with some significant projects under my belt. Here are a few select examples from my "portfolio":

• Canadian Patent Office Automation Master Plan – March 31, 1988
  I wrote at least half of this document, prepared most of the diagrams, most of the calculations presented therein.
• Integrated Spectrum Observation Center Manual – January 2015
  The ISOC was my largest software project, ~120,000 lines of code in total, and I also wrote this manual, along with some design documentation and an API reference.

I have attended several conferences and gave talks at other venues. Here are some select presentations:

• Metric symmetry by design: A Lagrangian perspective with computer algebra adventures, seminar given at the Cosmology group of Arizona State University, Tempe, Az, April 15, 2026
• Radio-metric navigation and the Pioneer Anomaly, talk given at the Canadian Center for Experimental Radio Astronomy Summer Camp in Carp, Ontario, August 2, 2024
• From stellar systems to the CMB: MOG across 15+ orders of magnitude, invited talk given on January 18, 2024, at the Challenges of Modern Cosmology workshop organized by the Universidad Complutense de Madrid (see also its video recording)
• Look before you leap: Using the Solar Gravitational Lens to explore exoplanets, talk given at the 8th Interstellar Symposium, Montreal, QC, July 10, 2023
• The Solar Gravitational Lens: Imaging Exoplanets, virtual talk via ZOOM, given to the North Houston Astronomy Club, May 28, 2021
