NOTE: This Resume is now two decades out of date. It’s more of historical document than anything else. I expect never to need an updated resume again. 🙂 My career page is likely somewhat more up-to-date.

Technical Interviewer & Hiring Manager: during most of my tenure at Microsoft I frequently interviewed job applicants for software engineer and related positions. In recent years my role expanded to that of “hiring manager”, having final say on whether or not a job offer would be extended to applicants on completion of the interview process.

Developer Division: 1998-2001

Author: Wrote MSDN Magazine’s Custom Add-Ins Help You Maximize the Productivity of Visual Studio .NET.

Staff Engineer: July 2000 through November 2001 worked in a part-time capacity on independent projects, including data mining the bug tracking and source code control databases for information on developer productivity, building tools to aid in that effort, as well as ongoing consulting to the build organization.

Release Development Manager: Until July 2000, lead a team averaging 20 in size, of builders and developers.

The build team’s responsibilities included daily builds and validation tests of Visual Studio .NET and related products, including service packs, QFE’s and component builds for other teams. Major accomplishments here include representing the team and significantly improving the perception of the lab throughout the division, while also establishing a much healthier and happier work environment for the builders themselves.

The development team owned both the tools and scripts used to execute the build, but also the fundamental tools and processes used to generate VS7’s setup using the Microsoft Installer. While managing and growing this team, I also acted as one of the primary architects of the new processes used in the lab to build VS7.
