Stanford Computer Systems Laboratory
Member of the Transactional Coherence and Consistency project
researching hardware supported transactional memory models. Research
focused on parallel programming with transactional memory. Built upon IBM's Jikes
Research Virtual Machine to evaluate programming models, benchmarks, and
new programming language features. Significant C++ development on our
architecture simulator, including moving from PowerPC-only to include
support for x86.

Buyer and Platform Technical Architect
As architect for Buyer 8.0 release was involved in content definition,
planning, feature design reviews, and operational execution. Evolved
development process through component ownership practices. Consulted on
refactoring to create application platform, the core of new Ariba products.
Drove code cleanliness projects to remove JDK 1.1 limitations and
supportability issues. Worked with legal, documentation, and engineering
on many third party licensing issues. Drove technical leader review
process, identifying future candidates, and worked with managers on the
candidate's career development.
Server Technical Lead
Led Buyer 7.0 Server team projects which involved design reviews,
schedule tracking, and issue resolution. Delivered refactoring of server
technologies such as object-relational mapping, RPC, and utility
libraries for use by other products. Ariba Analysis was built from
scratch on this platform and existing applications have begun adoption.
Converted from RSA to Entrust crytography to reduce cost of goods sold,
at the same time enhancing our security API. Created first unit test
infrastructure and unit tests, now integrated with JUnit. Created 8.0
requirements and initial designs for database archiving and data
migration. As acting manager, heavily involved in recruiting including
college hiring. As acting director, coordinated office move.
Member of original team that designed and implemented the Ariba
Buyer product. Drove engineering closure on first product
spec. Created the Approvable document architecture, the user
permissions model, and a Scheme interpreter for business
rules. Implemented SMTP client and server for
notification. Responsible for HTTP server used for printing and
attachments and later converted it to the servlet API. Created
Inspector tool for runtime debugging.
Created command line monitoring tools to automate
operations. Removed explicit locking from object model to simplify
API. Converted RPC from using a thread per client to worker queues
to improve scalability. Created javadoc doclet to allow fine
grain control over published API. Assisted globalization by
removing deprecated JDK 1.0 APIs. Converted all production batch
and shell scripts to Perl for portability.
Created and maintained development web site, mailing lists, and
Emacs development environment.

Co-author of the open source project Scsh, the Scheme Shell. Scsh is a
POSIX environment based on the Scheme dialect of the Lisp programming
language. Involved in all aspects of the system including design,
implementation, documentation, testing, and release. Scsh is used for
CGI scripts, network applications, and general purpose shell scripts.
Used Scsh to develop several applications including a mobile web browser
for the Apple Newton and a web server that is extensible in Scsh and
