People first. Good systems augment good people. I bring 30 years of IT experience to dependable technology for small businesses, executives, and complex organizations.

I am also conducting independent research into a specific aspect of gravitational physics.

Reading the evidence

Most of this CV comes from my own records. Where a public artifact exists, such as a repository, a release or a website, the claim links to it. Every module, project and community card carries one of two words: Public artifact when a linked public source backs it, Self-reported when it rests on my own records. The register below lists every public artifact and the date it was last checked.

How to read a record
Title and employer
Each role gives the title and the employer. For contract work it also names the client the work was done for, after “for”.
Engagement
How the work was arranged: Independent work; Employee; Contractor, vendor assignment; Contractor, staffing firm; Contractor, project; Self-employed; Student employment; Volunteer; Atos to Disney; Nonprofit leadership.
Disney
The executive-support work is one continuous role: October 2013–Present. Atos assignment: October 2013–November 2022; Disney employee: November 2022–Present.
Current roles
Several roles are current at once. Independent work, consulting and volunteer roles are separate from the Disney role.
Evidence links
Small links after a line, such as “repository” or “v0.82.1 release”, open the public artifact behind it. Being public does not mean a third party has verified the claim.
Status words
Public artifact means a linked public source supports the claim and anyone can open it. Self-reported means the claim comes from my own records and has no public artifact. In the service record the word sits beside the role when every contribution shares it, and beside each contribution when they differ.
Figures
Numbers come from the records as written. Where a figure is an estimate, the record says so, for example “approximately 95%” for the Confluence import.
Clearance
The Top Secret clearance is listed as previously held.
