🔧 Phase 4: Bug Fixes & Improvements ✅ COMPLETE

Fixed Issues

1. Response Schema Consistency ✅

  • Issue: Frontend expected stats?.data?.overview but API returned flat structure
  • Fix: Updated statsAPI.getOverview() to call /api/stats instead of /api/stats/overview
  • Result: Now returns proper AnalyticsResponse with nested overview field

2. ApplicationWithJobResponse Schema ✅

  • Issue: Job field was passing raw model instead of validated schema
  • Fix: Added JobResponse import and proper model validation in job_service.py
  • Result: API returns properly typed responses

  • Consistent error handling
  • Type hints in Python code
  • TypeScript strict mode
