B2B / Marketplace
Frontend
Next.js
B2B marketplaces typically force all users into a single experience, ignoring the fundamentally different needs of individual buyers versus company purchasing departments with approval workflows, budget tracking, and multi-user accounts.
Dual Authentication Portals
Separate login flows for individuals and organizations. JWT-based authentication with role-specific session management and permission controls.
Company Dashboard
Organizational buyers get procurement dashboards with budget tracking, multi-user account management, purchase order history, and approval workflows.
Individual Buyer Portal
Streamlined single-user experience with quick checkout, order history, and personalized recommendations based on past purchases.
Role-Based Access Control
Granular permissions for company accounts: purchasing managers can set budgets, team members can request purchases, and admins can approve orders.

Tools & Services
Next.js frontend with dual authentication flows routed through a shared Express.js API. JWT tokens encode user type and role, which the middleware uses to apply different business logic for individual versus company users.
Individual and company users have fundamentally different workflows but share the same product catalog and marketplace infrastructure.
Built a shared API with role-aware middleware. User type is encoded in the JWT, and all business logic branches based on user type. The frontend renders different interfaces from the same component library.
