HR teams at Deloitte, KPMG, SeamlessHR stuck with outdated assessment tools - manual grading, weeks to build tests, no actionable insights. Needed AI platform scaling from 5-person startups to 5,000-person corporations. I designed scalable assessment builder with AI question generation, role-based access for org hierarchies, analytics dashboard translating test data to hiring insights, and white-label capability. Built on WordPress for rapid iteration.

Result: 25 enterprise clients (Deloitte, KPMG, government agencies, NGOs) in 6 months, 100K weekly users, assessment creation from 2 weeks to 45 minutes, 92% retention, 2M+ assessments processed, 38% better hiring quality.
