June 11– March 14

Sabbatical

Occupied with various projects, often involving programming. Built my own computer. Administrated GNU FreeFont project. Projects include physics and mathematics, linguistics and typography. Traveled, read.

June 07– June 11

Scientific ProgrammerLeibniz-Institut für Astrophysik Potsdam

As a member of the German Astronomy Community Grid, worked on computing resource sharing on the grid. Collaborated with cosmologists to run very large astrophysical simulations by developing applications to distribute computing jobs among clusters, and to make terabytes of information easily available.

Researched, implemented, documented and published methods of integrating cluster use into the grid. Coordinated with other grid groups in maintaining compute resources. Wrote “virtual observatory” compatible database application with Web front-end. Helped maintain groupʼs Web site, including Web applications.

Sept 03– Dec 06

Scientific Programmer — Max-Planck-Gesellschaft - Albert-Einstein-Institut

Projects with the Numerical Relativity Group, including specification and purchase of clusters and programming. Primary concern: Cactus framework. For it, wrote utility modules, some involving physics and MPI parallel programming, helped scientists write interoperative code, participated in quality maintenance efforts, helped maintain group’s Web site.

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

Mar 98– Mar 01

Team Leader/Application Designer/Programmerasterion

Lead team of programmers through full production cycle: conception, gathering specs, design, documentation, coding, testing, deployment, and maintenance. Coordinated with quality assurance to maximize client satisfaction. Performed such managerial duties as time-lining, prioritizing, participating in top-level company meetings, hiring new employees, and reporting to upper echelons.

Produced Java thin client graphical user interface for the application suite. This tied two deals with major clients. Wrote and maintained suite’s libraries.

Wrote new applications for the firm's mainframe medical/insurance database application suite, re-wrote existing libraries to facilitate extension and debugging.

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++ for Windows, and a magnetic dipole tracking and display application in C++ for Mac. Participated in team to extend large clinical data analysis and display package in C for Mac.

Sept 88– May 92

Sept 80– Aug 82

Instructor/Teaching assistantTexas 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 a basic design agreed upon before coding any new project. Practice an iterative approach, involving milestones that bring users real functionality, in order to draw users into the project as partners, and involve quality assurance (code or personnel) from the start.

Teams

Lead a team of 2 to 4 programmers for two years, performing as supervisor, mentor, and representative to other departments. Worked as member of teams of a range of sizes, from a group of a dozen programmers. Often took sole responsibility for projects. Work well under pressure.

Algorithms

Academic specialty was in applied mathematics, especially numerical analysis, so had written hundreds of small number-crunching algorithmic programs, many of my own invention, before entering industry, where these skills were used either to implement new or optimize existing functionalities.

Environment

Wrote large and small programs for Windows, Unix, Linux, and Mac OS. Developed using modern IDEs, or with a text editor and a compiler. Worked on all levels: GUIs, APIs, libraries, and wrote real-time hardware-level code, for small devices, compute clusters, and network applications. Hacked more spaghetti code than you can twirl a fork at, but often designed from scratch.

Recent personal projects

International keyboard page in XML/XSLT, E-mail conversion utility in Python, HTML to LaTeX conversion program in Perl, 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, program in Java to draw families of geometrical curves, C++ library for physics using template metaprogramming, expression templates. System for display of LaTeX math formulas in web browsers using XSLT. Guitar tuner app for mobiles/smartphones in Java.
