Application Design — ShiftMesh (nurse shift-swap marketplace)
design_id: ad-shiftmesh-01 · type: web_app · status: concept · complexity: moderate · priority: high
Description: An internal marketplace where hospital nurses post, claim, and swap shifts within unit- and credential-based rules, with charge-nurse approval.
Purpose: Cut unfilled shifts and last-minute agency spend by letting qualified nurses self-serve swaps inside compliance guardrails.
Value proposition: Fewer holes in the schedule, less manager phone-tag, and an auditable trail that every swap stayed credential-compliant.
Target users: staff nurses · charge nurses · unit managers · the staffing office.
Technical design
- Architecture: Next.js front end + a Node/Postgres API; a separate eligibility-rules service gates every swap; an event queue drives notifications.
- Stack: TypeScript · Next.js · Postgres · Redis (locks on claimed shifts) · Twilio (SMS) · SSO via the hospital IdP.
- Key components: shift ledger · credential/eligibility engine · approval workflow · notification service · audit log.
- Data model: Nurse · Credential · Shift · SwapRequest · Approval · AuditEvent.
Functional design
- Core features: post an open shift · request a swap · auto-check credentials + overtime rules · charge-nurse approve/deny · audit export.
- User flows: Nurse posts a shift → eligible peers notified → a peer claims it → rules check runs → charge nurse approves → both calendars update.
- Integrations: the existing scheduling system (Kronos/UKG) · hospital SSO · payroll export.
Implementation
- Phase 1: read-only sync from the scheduler + the shift ledger.
- Phase 2: swap requests + the eligibility engine + approvals.
- Phase 3: notifications, audit export, and overtime/fatigue guardrails.
- Dependencies: scheduler API access · a credential data feed · IdP integration sign-off.
