A few examples of the technical decisions and responsibilities I bring to an IT team.
Acquisition integration
Consolidating two
Workspace environments
Following a corporate acquisition, I migrated a 60-user Google Workspace into an existing 220-user tenant. The scope included accounts, email, groups, Drive content, and shared drives.
We used a third-party service for email migration and validation. I independently worked out an approach to preserve the original IDs of externally shared Drive files and resolved individual Drive discrepancies.
Email and Drive cutover completed over a weekend with approximately three hours of downtime.
Audit responsibility
Security controls
with operational ownership
At GDS Link, I owned controls, policies, evidence, auditor coordination, and remediation for six SOC 2 audits, with the CIO providing management responses. I also supported approximately four additional customer-driven security audits each year.
Across my Istation and Amira tenure, I have completed seven more SOC 2 audits. My current responsibilities cover controls, policies, and IT evidence within a wider departmental evidence collection process.
Thirteen completed SOC 2 audits, with responsibilities spanning technical implementation and audit coordination.
