Enterprise backend API for managing leadership competency assessments with real-time tracking and Stripe billing.
Organizations running leadership competency assessments needed to create, distribute, and analyze them at scale — and to charge for the service — without stitching together separate survey, billing, and reporting tools. The system also had to group users by organization and share assessments accordingly.
We built an enterprise Node.js + TypeScript API with bulk CSV import/export for assessments, organization-based user grouping, Stripe subscription billing with webhook handling, and real-time notifications over Socket.io. Advanced analytics and competency comparison reports turn raw assessment responses into usable insight.
