Staffing App Development for AI Matching, Shifts, and Payroll Sync
We are a staffing app development company building worker apps, recruiter dashboards, and client portals with AI candidate matching, GPS-verified shift clock-in, and direct integration into the ATS and payroll systems your team already runs on. Built for agencies placing hundreds of workers a week, not a demo that breaks at scale.

The Real Challenges
Why Staffing Apps Fail Without AI Matching and Real Compliance Logic
KnockKnock, Here Is the Evidence We Solved These
"The AI matching cut our time-to-fill dramatically, and the GPS clock-in ended the payroll disputes that used to eat hours of our coordinators' time every single week."

Manual Resume Screening Cannot Scale
Recruiters reviewing hundreds of resumes a week against open roles burn hours on keyword scanning, and qualified candidates whose resumes use different terminology than the job posting fall through the cracks entirely.
Shift No-Shows With No Backup Plan
When a worker cancels a shift last minute and there is no automated way to broadcast that opening to a backup pool, the client site goes understaffed and the agency's reputation takes the hit, not just the missed placement fee.
Timesheet and Payroll Disputes
Without GPS-verified clock-in tied directly to payroll, disputes over whether a worker actually showed up, and for how long, eat recruiter time and create the kind of friction that drives good workers to a competing agency.
ATS Data Gaps Cause Duplicate Work
When the worker app and the ATS your recruiters live in are not connected, candidate data gets entered twice, statuses fall out of sync, and the agency loses the single source of truth that makes a placement business run smoothly.
Staffing Software We Build
Six Types of Staffing Software We Build End-to-End
Every type listed here links to the service page with full technical detail. This is the short version: what we build, what technology we use, and what you get.
Worker and Candidate Mobile Apps
iOS apps in Swift and SwiftUI, Android apps in Kotlin and Jetpack Compose, or a single React Native codebase for both. Workers browse open shifts, clock in and out with GPS verification, view pay statements, and upload certifications, all from one app.
iOS Development
AI Candidate Matching
Resumes and job descriptions parsed by GPT-5.5 into structured skills and experience, embedded as vectors, and ranked by semantic similarity. Surfaces qualified candidates that keyword-based ATS search misses entirely, cutting recruiter screening time significantly.
AI Development
Shift Management and Scheduling
Real-time shift posting, claim, and cancellation flows with push notification alerts. When a worker cancels, the open shift broadcasts automatically to a qualified backup pool ranked by proximity, certification match, and past reliability score.
React Native Development
ATS and Payroll Integration
Bidirectional sync with Bullhorn, JobDiva, and Greenhouse for candidate and job order data, and with ADP, Paylocity, and QuickBooks Payroll for GPS-verified timesheet data flowing directly into payroll processing without manual re-entry.
B2B SaaS Development
Recruiter and Admin Dashboards
Internal dashboards for recruiters and operations teams to manage candidate pipelines, fill rates, shift coverage, and compliance status across every active placement. Designed in Figma around the daily workflow of a busy staffing coordinator.

AI MATCHING AND COMPLIANCE ARCHITECTURE
What AI Matching and Workforce Compliance Architecture Actually Means
Most staffing apps run a basic keyword filter against a resume database and call it matching. Real AI matching means every resume and job description is embedded as a vector capturing skills and context, not just exact text overlap, so recruiters see candidates a keyword search would have missed entirely.
We build this into every staffing platform from the first sprint: structured resume parsing via GPT-5.5, GPS-verified shift attendance tied directly to payroll, and compliance workflows for background checks and worker classification that protect the agency, not just the placement. Compliance is treated as an architecture decision, not paperwork bolted on afterward.
GPT-5.5 parses resumes into structured skills and experience, then ranks candidates against open roles using vector similarity rather than exact keyword overlap.
Geofenced clock-in and clock-out confirms a worker was physically on-site, eliminating buddy punching and the payroll disputes that come from unverifiable attendance.
Bidirectional sync with Bullhorn, JobDiva, and Greenhouse keeps recruiters working in the system they already know while the mobile app stays current.
Verified timesheet data flows directly into ADP, Paylocity, or QuickBooks Payroll, removing manual re-entry and the errors that come with it.
