Overview

• I have a strong appreciation for the need to do up-front systems analysis in order to specify most projects properly.
• My background in abstract mathematics tends to give me a perspective on problems very different from that of the typical programmer.
• Believing in proper software engineering process, I have been an advocate for better procedures and standards.
• I have worked in a broad range of applications, with a wide variety of languages, platforms, tools, and technologies.

Work Experience

• 1999, 2000-2002 — Senior Software Engineer

  Groton Neochem, LLC. (analytical chemistry software)

  Neochem wrote an analytical chemistry package, used by pharmaceutical companies to help organize and understand their chemical libraries. I was primarily responsible for all aspects of the Web-based client, and major portions of the UI for the C++ client (including, but not limited to, documentation, specification writing, coding, and testing). Other responsibilities included determining and writing specifications for work for some customers, and server work related to all the above tasks. Primary languages used were C++ and Javascript, with some use of Oracle/SQL and Java.

  Accomplishments: As a lasting accomplishment, probably the most important thing I did was make all the Web site's code easily reuseable. In addition, I:

  • Designed (as part of a team) and wrote a substance evaluation and tracking system (including work in Oracle/SQL).
  • Made 3-D data tables, with a good examination and execution GUI.
  • Used COM and MIME to transfer and analyze Excel files across the web.
  • Wrote an automatic documentation system for the web client code in XML.
  • Wrote a substance registration and tracking system (in Javascript, C++, and an internal language).
  • Wrote data acquisition and analysis modules for several chemical analysis instruments (C++, internal language).
  • Improved client/server communications.
  • Designed and executed a major restructuring of the basic UI unit of the C++ client/server application, allowing clearer use and organization of worksheets (C++).

• 1999 - 2000 — Senior Software Engineer

  Waterloo Maple, Inc. (symbolic math software)

  Maple writes a symbolic algebra package, used by industry and students to solve problems symbolically (as opposed to numerically, though it does that too). I was responsible for maintaining the GUI for the current version and researching changes for a new version.

  Accomplishments:

  • Helped design and prototype a next generation of algebraic math software in Java; it was much easier for non-specialists to use, with more available and integrated help everywhere.
  • Mentored several less experienced programmers.

• 1996-1998 — Senior Software Engineer

  Macsyma, Inc (Symbolic Math Software)

  Macsyma was a friendly competitor of Maple, and made a similar program. It also made a finite element analysis program named PDEase. I was responsible for various aspects of MFE, the front end to both the symbolic algebra program and PDEase, and for communications between MFE and PDEase.

  Accomplishments:

  • As lead developer, designed and created a natural language help system intended to aid naive users in finding needed mathematical knowledge (C++, MFC).
  • Designed, specified, and wrote improvements to the text system, allowing superscripts and subscripts at any number of nested levels, with a clear and easy interface for changing them. (C++, MFC).
  • Researched and wrote a tetrahedralization procedure for a three-dimensional version of our finite element analysis package PDEase (Pascal).
  • Designed, specified, and wrote a system of graphics styles (using the in-place attribute system as its substrate) allowing easy and reproducible customization of graphics (C++, MFC).
  • Maintained the Macsyma math engine (LISP).

• 1995 — Software Consultant

  ViaTech

  At the time, ViaTech did CAD consulting for the automotive industry.

  Accomplishments:

  • Developed a CAD viewer using C++ and MFC.
  • Ported this viewer to UNIX using Willows.

• 1993-1995 — Software Engineer

  Sigma Design, Inc.

  Sigma Design makes an architectural CAD package (ARRIS), running on various UNIX systems (Sun, HP, IRIX, Sco UNIX), Microsoft Windows. I was responsible for all aspects of the C portion of the program, including design and development of new features, integration of all platforms, porting to new platforms (the most notable being the port to Microsoft Windows), and support of the internal Sigmac language (used by other developers internally, external contracted developers, and end users).

• 1991-1993 — Software Engineer/Q.A. Engineer

  ComputerVision, Inc.

  Tested a solver-based CAD package (DesignView) running under Microsoft Windows and various UNIX systems.

  Accomplishments:

  • Planned and implemented test plans for version 3.1 of DesignView
  • Planned, implemented, and automated test plans for version 4.0 of DesignView.
  • Was the sole developer for the last release of the DesignView Applications Library, a package of engineering examples for use with DesignView.
  • Helped with the port of DesignView to UNIX.

• 1987-1991 — Programmer, Lab Assistant

  Smithsonian Astronomical Observatory

  Designed and wrote data analysis and testing procedures for the ROSAT and Einstein satellites (KSH script, Ratfor).

  Ported software from a Data General/VAX to a Sun/UNIX workstation (FORTRAN, C, EQL, shell script).

  Wrote real-time data retrieval, and data-analysis routines for the EXITE high-energy X-ray telescope.

  Helped build the EXITE high-energy X-ray telescope.

  Work at the Smithsonian varied from year to year between full and part-time.

• 1988 — Intern

  Kodak Electronic Printing Systems, Inc.

  Worked with the color science group developing and testing image-processing software for transformations between the (additive) color space of the computer screen and the (subtractive) space of the printer.

Research and Publications

• 2002

• 1989 — Mount Holyoke College

  "Counting critical points of real polynomials in two variables"

  I worked with Prof. Alan Durfee and a team of other undergraduates which looked into the distribution of ratios between maxima and minima of polynomials in real projective space. Much of this work investigated the relation of this problem to singular arrangements of curves in a plane. I co-authored a paper (published in American Mathematics Monthly, v. 100, n. 3, pp. 255-271) reporting the outcome of this work.

Education

I have a BA in Mathematics from Harvard University (1991).
