Garrett Holmes

Executive assistant to the Chief Nursing Officer · Denver, CO

• Replaced paper schedules across seven staffing areas with cloud-based, formula-driven workbooks, saving each manager several hours of administrative work per week and giving staff real flexibility in how shifts get filled. The float pool is one of the seven.
• Trained colleagues on AI tools and used AI to advance my own workflows, on non-patient work; no patient data goes into AI tools.
• Designed and built a mobile float-pool scheduling application (Google Apps Script + Sheets): no-login staff links, scheduler day and grid views, automatic flagging when availability changes after a shift is booked, live calendar feeds, and a regression suite that runs before every deploy. In IT security review, with a written answer package I prepared for that review. An operational tool, not a clinical one.
• Support the Chief Nursing Officer and four executives across a nursing organization of 400+: calendars, expense reports, invoicing, purchasing, financial reporting, data analysis, technical support, and special projects.
• Built data-analysis automations that reconcile patient logs against billing records, surface financial trends, apportion invoices across 25+ departments, and pinpoint financially underperforming areas.
• Moved license tracking for 200+ registered nurses onto NurSys automated verification, cutting the manual work of Joint Commission Primary Nurse Verification compliance.

Rebuilt a Denver childcare agency's website (live, four days from brief) and built the booking and dispatch system behind it (on staging, not yet used by families). The model may only copy date and time words out of a parent's text; a grounding check verifies each one, and an ordinary parser does the date math.

Reply drafts have no send path in the code: the owner sends every one.

Typed text becomes a draft sign-up sheet or poll. Claude Haiku 4.5 drafts it, with a Workers AI fallback; if both fail, the person keeps their typed text.

On 35 written test cases, including a prompt-injection case and a Spanish-language request, Haiku matched Sonnet, which costs about 2.5 times as much, so Haiku shipped. Capped at 200 calls a day (about $16 a month).

A personal agent built on the Claude Agent SDK, with a separate tool allowlist for each context; the mail-ingest path gets no tools at all. Outside text (mail, calendar, documents) is wrapped as untrusted data, never read as instructions.
