EXPERIENCE

(PTC) / Mathsoft Needham, MA

2006-2009 Principal Quality Engineer for Mathcad,

before & after PTC acquisition of Mathsoft:

Developed automated tests,

written in three Mathcad-specific test languages

(MC debug, Mugs/TCL, MC engine-test),

of various mathematical features, including:

ordinary differential equation solvers;

linear & nonlinear optimization;

gradient, Jacobean and other vector & matrix computations;

dynamic unit checking;

fitting & spline interpolation functions;

derivatives, integrals,

and other symbolic computations.Analyzed results of over 100,000

such automated tests, for each new Mathcad build.Maintained the test harness that ran these tests, using

Perl, Windows (DOS), Bash, ClearCase & Microsoft SQL Server scripts.

2005-2006 Needham, MA

Senior QA Engineer at a web

publishing company:

Tested various new features for the

and its partner sites, including webcasts, user registration

and database logging.Extended an existing HttpUnit (Java) program to test for valid links

from a starting web page to any specified depth.Wrote a Bitpipe Partner Site Test Plan, for use by junior

or contract QA engineers.

2000-2005

Art Technology Group

(ATG) Cambridge, MA

Senior QA Engineer at a Java-based

web commerce software company:

Designed, managed development of, and maintained ARTS (the

Automated Repository Test Suite), used to test ATG Dynamo's

SQL Repositories, which customers use to access their database;

and tested on various databases.Developed JUnit code for tests of the ACO (Adaptive Customer

Outreach) product; also tested the ACO UI, running on

BEA Weblogic.Developed and used a Java servlet that tests various

Repository API methods, with arbitrary inputs specified in a

browser.

1997-1998

(Powersoft division) Concord, MA

Product Support Engineer for PowerSite, a

web application development tool:

solved customer problems, via phone, e-mail & newsgroup,

involving:

installation, the HTML editor, Java applets, database connections,

the DataWindow Design-Time Control, ActiveX components, client-side &

server-side scripting,

and deploying to supported application servers

(PowerDynamo, Microsoft ASP/IIS, Netscape Livewire).

1995-1997

(formerly Real Software Solutions) Burlington, MA

Consulting Engineer at a tiny start-up with

a web application development tool.

Performed various tasks, as needed:

QA, including testing database connections;

developed sample applications;

release engineering of C++ and Java builds;

taught a training course.

1992-1994

(now BAE) Burlington, MA

Power Systems Analyst:

designed software that

supported analysis of vulnerabilities

in electric power transmission systems.

Developed an interior point nonlinear

optimization algorithm, using a sparse implementation of

the logarithmic barrier function method, for computing optimal

real and reactive power flows.

1983-1987

(now BAE) Burlington, MA

Scientific Programmer:

developed aircraft and missile simulations;

failure detection, Markov chain and Kalman filter software.

EDUCATION Concord, MA

Two-term (1997-98) course in Java Programming, taught in-house at Sybase.

1986-1991 Providence, RI

M.S. (1988) degree in Applied Mathematics.
