Experience

  • Evolvability: A Formal Approach

    My PhD dissertation addresses the question: What are the logical requirements that need to be in place for evolution by natural selection to produce complex life? It develops a novel mathematical formalism to treat rigorously an area that had been covered mainly through verbal speculation. It also touches on many interesting questions, such as whether there is likely to be life on other planets, or life evolved within a computer.

  • CSAPS Video Library

    This app is used by hundreds of cosmetic surgeons in Canada to browse and watch encrypted streaming videos of plastic surgeries so they can maintain their medical skills. It has high security requirements, a high-polish design, and a custom back-end. It is also localized in French and English, implements AirPlay, and more.

  • McKinsey and Company

    I led the development of two portfolio apps used by McKinsey & Co. to sell its software services. These codebases have been forked and reused within the firm dozens of times, so that this work is now used globally in elite business settings around the world. However, because of the firm's confidentiality requirements, I can only present this work in a controlled environment where I can offer a sanitized demonstration. (Sorry!)
