HRMS Payroll Integration

FastAPI microservices that synchronized biometric attendance, payroll, and compliance records.

Problem

Finance and HR teams managed parallel data sources—attendance biometric devices, payroll spreadsheets, and compliance checklists. Manual reconciliations consumed hours each week, and data mismatches delayed salary processing.

Approach

• Designed modular FastAPI services with Celery workers to ingest biometric logs and normalize them against HR master data.
• Orchestrated infrastructure with AWS ECS, S3, and Parameter Store for secure config management.
• Implemented automated validation tests and Slack alerts so discrepancies were surfaced instantly.

Impact

Payroll preparation time dropped by 40%, compliance checks were audit-ready, and the platform now produces executive dashboards summarizing workforce costs, overtime, and leave trends each pay period.
