Résumé

  • About 20 years experience writing advanced system level and scientific code in C++, in the industry, an academic setting, and in the free software community.
  • Through scientific background and experience with a wide range of languages and techniques very proficient with domain-specific modeling and design.
  • Very experienced with portable, i.e. platform independent development. This applies as much to the source code as to the infrastructure (building, testing, packaging).
  • Experience with Medical Imaging software development, as well as standardization work.
  • Many years of experience in mentoring developers and coordinating projects

Experience

Mentor Graphics (2010 – present)
Software Architect
  • Design and develop numerical libraries in the High Performance Embedded Computing (HPEC) space.
  • Port HPC code to various platforms including Cell/B.E. and NVidia CUDA.
  • Develop integrated development workflows from prototyping (Matlab, SciPy) to target-specific optimization (C++, compiler intrinsics, etc.)
  • Manage releases for various products.
  • Coordinate architecture-level efforts related to various projects.
  • Work on VSIPL++ standardization within OMG.
  • Co-chair HPEC Working Group within OMG.
CodeSourcery (2005 – 2010)
Sourcerer
  • Design and develop numerical libraries in the High Performance Embedded Computing (HPEC) space.
  • Port HPC code to various platforms including Cell/B.E. and NVidia CUDA.
  • Manage Sourcery VSIPL++ releases.
  • Work on VSIPL++ standardization.
ORTHOsoft (2001 – 2004)
Software Developer
  • Design and develop a new document-centric architecture based on an Electronic Patient Record.
    This includes various services such as persistence, recording / playback, and logging, and is based on XML (using DOM and SAX APIs).
  • Design and develop a portable component model that was used to refactor (i.e. modularize)
    the whole product suite.
  • Develop and maintain the Motion Capture component with its principal implementation using
    the NDI Polaris Tracking System. Bind this component to a scene graph (based on openGL and OpenSceneGraph) for real-time rendering of tracked surgical instruments.
  • Develop a scripting frontend (python) for a number of components using boost.python
  • Enhance the development environment by writing a new build system (using MSVC++, gcc, MipsPro, make, autoconf), a new unit testing framework (using qmtest), code documentation tool (using synopsis), and internal web site (using apache, a wiki, in-house cgi scripts, etc.).
  • Enhanced the software’s portability to now support MS Windows, GNU/Linux, and IRIX.
Architect and Principal Developer

Fresco is a highly modular, multi-threaded, distributed 3D enabled windowing system, based on a persistent scene graph with server-interpolated high color/spatial resolution and server-side UI components.

  • I designed and implemented most of the system using CORBA IDL, C++, Python. The implementation contains various system level and graphics libraries to make it highly portable, scalable and extensible. Lower level APIs that are being used include openGL, POSIX, CORBA 2.3, etc.
  • I implemented the build system for Berlin using tools such as make, autotools, perl
  • I presented the project at various international conferences, such as the Ottawa Linux Symposium (Canada) or the LinuxTag (Germany)
SIGGRAPH Montreal (2001 – 2002)
Member of the founding comitee
The Synopsis Project (2000 – present)
Coordinator and Lead Developer

Synopsis is a modular source code inspection tool, mainly designed to generate reference manuals from inlined documentation. It supports a variety of languages through the use of pluggable parsers, as well as a wide range of output generators, such as HTML, XML, or UML graphs.

  • I designed the overall layout of the framework, the data flow, as well as the class hierarchy used.
  • I implemented the core of the application (in python), as well as some of the parsers and formatters (C++, python).
