I've been fortunate enough to have made a career out of
writing software - here are some of the projects I've worked
I've been building Version Control tools for
the last 15 years:
I help ensure that VSTS has world-class
version control offerings and that our
customers are successfully using Git
and TFS Version Control.
I developed management and monitoring tools
for GitHub's network of fileservers and
ported these monitoring tools to the
on-premises GitHub Enterprise offerings.
I developed the underlying Git
repository management in Visual
Studio 2013 and newer. This low-level
functionality is provided by the
powerful libgit2 library and
compatible with the core git
My Git repository merging functionality
is at the heart of Team Foundation
Server's pull request feature.
In addition, I developed the Git
protocol handling functionality
for fetching and pulling over HTTP.
Team Explorer Everywhere is a cross-platform suite of clients for
Microsoft Team Foundation Server, including a standalone client,
a plug-in for the Eclipse IDE and a command line client. (Formerly Teamprise Client Suite.)
Remote Accelerator is a single-user version
control proxy for Team Foundation Server.
It is optimized for a single developer
working remote from the server, and
includes a clever cache seeding
technology to keep the cache pre-filled.
Vault is a version control tool which was designed to be a compelling
replacement for Visual SourceSafe. Vault provides advanced version control
operations including atomic transactions and rename support while retaining
a light footprint and tight support to Microsoft Visual Studio.
SOS Collab is a remote access front-end for Visual SourceSafe with integrated
bug tracking and team collaboration tools. The collaborative features have
since been moved to a separate product,
which integrates with both SourceOffSite and Vault.
I maintain and contribute to a number of
open source projects:
I'm the co-maintainer of libgit2, a
portable, pure C implementation of
the Git repository management library.
It powers Git hosting providers
Visual Studio Team Services,
as well as client tools like
amd Visual Studio.
The C# bindings for libgit2, providing
an easy-to-use .NET library for Git
A simple .NET API for the Visual Studio
Team Services and Team Foundation
Server REST API.
I managed the heterogenous CI build network
for this open source word processor.
Before Version Control, I worked in scientific
I helped maintain the heterogeneous
network of Unix development and build
servers and helped port the
Mathematica 3 kernel to PowerPC
My then-coworker, Dan Brumleve, came up with the idea of
a web-based front-end to Mathematica, and wrote
the initial version of The Integrator. I rewrote it to
become the second generation.
It still lives, but fortunately using webMathematica
instead of any code I wrote.
NCSA CSD was a front-end for searching the
Structural Database of organic compounds and creating
molecular representations that could be visualized using
MacMolecule in 3D ball-and-stick representations.
NCSA Waltz is a front-end to
which itself was an application for computing electron density of molecules
back when you needed supercomputers to run Schroedinger's equation.
Amusingly, NCSA DISCO doesn't exist anymore; this is all done by
PC-GAMESS on a puny Linux box.
