HR Platform Modernization: From Legacy to Real-Time Hiring

The Challenge

A staffing agency managing 500+ placements per month was running on a 12-year-old PHP application. The system had no API integrations, background checks were initiated via email, and recruiters tracked candidates in a combination of the legacy app and personal spreadsheets. Time-to-hire averaged 28 days, and verification delays accounted for 40% of that timeline.

Our Approach

We rebuilt the platform using a modern stack: NestJS API backend, Angular frontend, and MongoDB for flexible candidate profiles. The architecture was designed around the recruitment pipeline metaphor, with clear stages and automated transitions.

Verification Automation: We integrated with three background verification providers via their APIs, creating a unified interface that dispatched checks based on role requirements and geography. Results were pulled automatically and mapped to a standardized scoring rubric. Recruiters received notifications only when manual review was needed.

Candidate Pipeline: A Kanban-style interface gave recruiters real-time visibility into every candidate's status. Automated actions triggered at stage transitions: assessment invitations, interview scheduling requests, reference check initiations.

Analytics Dashboard: Recruiting managers gained access to funnel analytics showing conversion rates at each stage, time-in-stage metrics, and source effectiveness comparisons. These insights drove process improvements that compounded over quarters.

Results

• Time-to-hire reduced from 28 days to 17 days
• Verification turnaround reduced from 11 days to 3 days
• Recruiter throughput increased by 35% per person
• Candidate experience NPS improved from 32 to 67

The platform now handles the full lifecycle from job requisition through onboarding, supporting 600+ placements per month with the same team size.
