Vice President of Development (1998 - 1999)
Director of Development (1996 - 1998)
Director of Graphics Development (1995 - 1996)

MathSoft, a publicly traded company and producer of S-PLUS, purchased TriMetrix (of which I was Cofounder/CEO) in order to obtain the graphics and GUI technology from Axum, and also to obtain the development team that had produced Axum.

• Was part of management team that doubled revenues of established division in less than 4 years
• Merged S-PLUS and Axum development teams into team which produced numerous successful releases on Windows and Unix

TriMetrix created the Axum Technical Graphics and Data Analysis software package. In 1995 the company was sold to MathSoft, a publicly-traded company, and almost all employees were transferred to MathSoft.

• Rapidly grew business
• Was personally engaged in all parts of business: strategic vision, finances, hiring, team development, marketing, sales, customer support, development

• Negotiated long-term contract that made Axum the graphics engine for SPSS for DOS
• Negotiated sale of company to MathSoft

Aptech Systems created Gauss Mathematical and Statistical System. In 1988, I sold my shares of the company to a group of private investors.

• Rapidly grew business

• Was personally engaged in all parts of business: strategic vision, finances, hiring, team development, marketing, sales, customer support, development

• Is an easy-to-use and robust platform for implementing efficient, distributed and parallelized statistical and data mining algorithms.
• Allows statistical and data mining algorithms to be computed rapidly on data with millions of records (rows) and thousands of variables (columns).

Role: Designed and developed

• Is an exploratory data analysis and statistical modeling program with a heavy emphasis on graphics; the program of choice for many statisticians and data analysts; heavily used in the biopharmaceutical industry, on Wall Street, and in academia
• Based on S language, developed at Bell Labs, which won the 1998 Association for Computing Machinery (ACM) Software Systems Award
• Graphics and GUI for S-PLUS for Windows based upon Axum technology

Role:

• Led the design, development, and releases of S-PLUS for Windows, and personally participated as active developer
• Managed development and releases of S-PLUS for Unix

• Is primarily a technical graphics package providing advanced 2D and 3D graphics; also includes an extensive set of statistical and data manipulation facilities
• Won the PC Magazine’s Editor’s Choice Award as the best technical graphics package
• Its graphics and GUI have become the graphics and GUI for S-PLUS for Windows
• Is tightly linked with MathCAD, the world’s best-selling engineering software, to provide its 2D and 3D graphics capabilities
• Was bundled with the DOS version of SPSS in the early 1990’s to provide 2D and 3D graphics capabilities for that program
• A fairly recent review available on the web is: http://www.stats.gla.ac.uk/cti/activities/reviews/97_02/axum5.html
• Further information is available at: http://www.tools.scia.be/Mathsoft/axum6/axum6.htm

Role:

• Led the design, development, and releases of Axum for DOS and for Windows
• Wrote the C-like interpreter and much of the internal architecture

• Contains an extremely fast matrix programming language in which numerous statistical, econometric, and mathematical algorithms are implemented; has some of the most advanced optimization algorithms available anywhere
• Won PC Magazine’s Editor’s Choice Award as the best mathematical programming environment
• Is the package of choice for high end quantitative analysis in economics, political science, sociology and also in many industrial applications
• Some recent reviews available on the web are:

• Further information is available at: http://www.aptech.com

Role:

• Led the design of the Gauss Programming Language
• Designed and wrote, in the Gauss Programming Language, hundreds of mathematical and statistical routines. Nearly all statistical routines use out-of-memory algorithms that allow essentially unlimited numbers of observations.
