Morgan Stanley, Credit Risk group, 9/08 -

Bloomberg LP, Trading Systems group. 4/07 - 5/08. Senior Developer (and briefly Lead Developer) for the Ticketing API, which wraps millions of lines (and two decades) of legacy Fortran and C code in a clean, safe C++ interface. My responsibilities included designing new interfaces and connecting them to old code, reworking existing code to handle pervasive features such as a new naming system for financial securities, and advising colleagues about good C++ design.

dynagraph.org. 12/05 - present. Developer and maintainer of the Dynagraph dynamic graph visualization library. I created, maintain, and distribute this open-source software, which is implemented in platform-neutral C++. Development involves design/discussion/implementation of new features, refactoring, maintenance and release of multiple simultaneous versions, and supporting developers. I am also working on a new higher-order graph data structure to be submitted to Boost.
My primary client (12/04 - present) is the Dynasty research team (http://dyna.org/Dynasty) at Johns Hopkins University, who are building a browser for huge, changing graphs (networks) that uses Dynagraph for drawing.

Primedia Software-on-Demand. New York City. 3/04 - 11/05. Consultant. Developed the EduCast Client, a native Win32 application deployed to hundreds of school computers which monitored and managed running software through integration with the Softricity SoftGrid Client. Other projects included writing of glue code for processing files downloaded by Fazzt satellite software; writing a C++ ACE module to forward authorization requests to the .NET world using COM; and the development of three generations of a complex installer using NSIS, InstallAnywhere.NET, and then WiX (including writing extensions for Task Scheduling).

AT&T Labs Research. Murray Hill and Florham Park, NJ, and Soho NYC. 9/97 - 8/03. Consultant to Information Visualization Group. Developed graph drawing algorithms and applications in Windows and Java. Designed and implemented a templated C++ graph data structure, a client-server architecture for graph drawing engines and clients, and C++, COM, and text-based APIs. Dissatisfied with MFC's OLE support, built a replacement Windows application framework, Montage. Developed prototypes of a browser for exploring huge graphs.

Department of Computer Science. Berkeley, CA. 9/96 - 8/97. Undergraduate researcher. Developed an application of the Berkeley Analysis Engine (http://www.eecs.berkeley.edu/Research/Aiken/bane.html) to analyse and interactively display the data flow of Java programs. Written in SML, C++, and Emacs Lisp.

Berkeley Systems. Berkeley, CA. 8/93 - 1/95. Tracked down bugs in After Dark screen savers and the Expresso PIM. Maintained the C and assembly code of After Dark or DOS and added internationalization and network features. Joined a spin-off project and developed early software to "skin" Windows.

Education

New York University. Currently attending the Masters program in Computer Science, specializing in User Interface and Graphics.

University of California at Berkeley. B.A., Computer Science (Honors) and Comparative Literature, 1997. Award for Excellence in Undergraduate Research. GPA: 3.8 in CS, 3.6 overall.

Amherst Regional High School. Amherst, Massachusetts, 1992.

Software

Dynasty. Large graph browser which uses Dynagraph for layout. By Jason Eisner and the Dyna team; I contribute ideas and occasional bug fixes. http://dyna.org/Dynasty
