Role focus and current roles

The summary itself is at the top of every page, under the name. This chapter adds the role focus and the four current roles.

Role focus

Current postings

These roles run at the same time. The independent work, the consulting practice and the nonprofit are separate from the Disney role.

Oct 2013 – Present · Atos to Disney

Senior Systems Analyst, Executive Support

Walt Disney World · Orlando, Florida

Provides technology support and advice to Walt Disney World executives at vice-president level and above and WDW Legal. Served through Atos from October 2013 to November 2022, then joined Walt Disney World Enterprise Technology as an employee. Work spans enterprise support, secure remote access, records and knowledge migrations, and coordination with information security teams. Helps executives, Legal staff, and colleagues work reliably and securely, with less disruption.

  • Exported the team's OneNote knowledge base to Markdown with attachments intact, shared the export and method with the team, and used a copy for a Confluence migration with an approximately 95% successful import. Documented the migration's limitations.
  • Added an experimental analysis of relationships between notes, including which documents supersede others, so current material is easier to find in search. It is non-deterministic, so it is used as an aid to human review.
  • Wrote the policy for migrating WDW Legal records from several sources to NetDocuments and coordinated LegalOps training on retention and retrieval.
  • Recovered lost or fragmented data and reports for clients on several occasions, saving from about an hour to several days of rework each time; this work contributed to a Disney Recognition award in 2026.
  • Liaison between executives and Global Information Security; advised WDW Legal on modernizing its BYOD policy and forensic investigation methods.
  • Moved WDW Legal executives, paralegals and support staff to secure remote work in 2020 using Citrix and two-factor authentication, procured equipment for long-term remote work, and strengthened home networks for the added traffic.
  • Located, organized and migrated WDW Legal PST archives to Exchange Online, with access granted to the correct attorneys and paralegals.
  • Developed and delivered training to counter spear-phishing campaigns; worked with eDiscovery on preserving digital evidence and records.
  • Proposed to leadership a review of WDW Legal's digital assets based on confidentiality, integrity and availability (CIA triad) principles.
  • Supported the WDW Legal move from eDOCS to NetDocuments (in progress in 2019).
  • Administered accounts, file and system access, and conferencing: Active Directory and Azure AD, Exchange Online, SCCM, OneDrive, BlueJeans, Zoom and Polycom.
  • Subject-matter expert for Disney IT support and field teams on PC, Mac, application and network issues; individual and group instruction for executives and support staff.
