Employment

June 07–
Present 		Scientific Programmer — Astrophysikalisches Institut Potsdam

As a member of the German Astronomy Community Grid, work on computing resource sharing on the grid. Collaborate with cosmologists making very large astrophysical simulations to conveniently move compute jobs among clusters, and to make terabytes of information easily available. Research, document, and implement methods of integrating cluster use into the grid.

Sept 03–
Dec 06 		Scientific Programmer — Max-Planck-Gesellschaft - Albert-Einstein-Institut

Worked on many projects with the Numerical Relativity Group, including specification and purchase of clusters and programming. Primary concern was the Cactus framework, for which wrote several utility modules (“thorns”), some involving Physics and MPI parallel programming.

Pushed for multi-core processors and InfiniBand networking in group’s new cluster; Belladonna is judged the best for running group’s simulations.

Mar 98–
Mar 01 		Team Leader/Application Designer/Programmer — asterion

Lead team of programmers through full production cycle: conception, gathering specs, design, documentation, coding, testing, deployment, and maintenance.

Produced Java thin client interface for mainframe medical/insurance database application suite. This tied two deals with major customers.

Wrote and maintained suite’s libraries. Worked closely with quality assurance group to maximize client satisfaction. Performed such managerial duties as time-lining, prioritizing, coordination with other departments.

June 92–
Jan 98 		Data Analyst and Programmer — CTF Systems Inc.

Responsible for research and implementation of algorithms for imaging of neuromagnetic data, and for solving data noise problems. Wrote analysis programs in C++, C, RLab, and Mathematica.

Designed, wrote real-time neural stimulus sequencing package in C++ and Java for Windows.

Designed, wrote magnetic dipole tracking and display application in C++ for Mac. Member of team on a large data analysis and display package in C for Mac.

Sept 88–
May 92 		Computer lab tech — SFU Math Dept

Maintained networked computer lab. Aided graduate students with computer use, typesetting and adding graphics to theses, and Internet connectivity. Assembled and maintained computer network, general system administration.

Sept 82–
May 91 		Teaching assistant — SFU Math Dept

T.A.’d most undergraduate applied Math courses: Calculus, Introductory and Advanced Linear Algebra, Introductory and Advanced Ordinary Differential Equations, Partial Differential Equations and Boundary Value Problems, Introductory and Advanced Numerical Analysis, Vector Calculus, Linear Programming, Business Math courses.

Sept 80–
Aug 82 		Instructor/Teaching assistant — Texas Tech Math Dept.

Taught Calculus II, Geometry, Business Math.

Computer experience

Design Completely designed several major industrial products, as well as dozens of smaller ones. Prefer to have fairly complete design agreed upon before coding any project, but practice an iterative approach, involving smaller increments that bring users real functionality, in order to draw users into the project as partners.
Teams Lead a team of 2 to 4 programmers for two years. Worked in teams of a range of sizes, from a group of a dozen programmers, and often had sole responsibility for projects.
Environment Wrote large and small programs for Windows, Unix, and Mac OS. Develop using modern IDE’s, or with a text editor and a compiler. Hacked more spaghetti code than you can twirl a fork at, but often design from scratch. Work well under pressure.
Programming Database programming, user interface (both GUI and text-only), animated graphics, real-time, TCP/IP communications, hardware programming, high-performance cluster programming, Web page programming, and lots of number crunching.
Personal International keyboard app in XML/XSLT, E-mail conversion program in Perl and C, gravitation simulator in Java and XML, tank game port to Java, various web-based toys in JavaScript, some using CSS and the DOM (calculator, animated smiley-face, paint program, Unicode browser, etc.), small web browser in Java, Web miner in PHP, Java, and MySQL, math program in Java to draw family of curves, C++ template library for tensor algebra featuring template metaprogramming, expression templates
