What you need to provide
What I Can Build for You
Everything your SaaS needs for users, orgs, and access control—implemented cleanly. Drop-in UI, predictable APIs, and secure defaults. I build it to be scalable, auditable, and easy to extend.
User Management
Admin UI + CRUD, profiles, preferences, and account controls.
Admin UI screens + API endpoints + DB migrations
Role-based access verified with test users
Supports user profiles, preferences, and account management
Multi-Tenancy
Organizations, members, workspaces, and tenant isolation patterns.
Tenant middleware, org/workspace schema, tenant switcher, isolation tests
Tenant context enforced server-side (cannot cross-tenant)
Works with schema-based or row-level tenancy
Access Control
RBAC + permission policies for granular authorization.
RBAC policy engine, permission UI, API checks
Role-based access verified with test users
Supports granular permissions and policy management
Team Management
Invites, role assignment, and member lifecycle.
Invite system, role management, member lifecycle
Team invites and role assignment tested
Email invitations with role selection
Billing Integration
Stripe subscriptions, plans, entitlements, and webhooks.
Stripe integration, subscription management, webhooks
Payment flows and subscription management tested
Supports recurring billing and plan changes
Custom Domains
White-label branding, custom domains, and tenant settings.
Custom domain support, branding settings, DNS configuration
Custom domain verification and branding tested
Supports white-label branding and custom subdomains

Acceptance Criteria (Examples)
These are examples of what we'll test to ensure your system meets the highest standards
Tenant Isolation
Cross-tenant access attempts return 403 and log an audit event
RBAC Enforcement
Role changes apply immediately and are enforced at API level
Invitation Flow
Invitation process works end-to-end (email → accept → role applied)
Session Management
Sessions can be revoked and invalidated
Email Verification
New users must verify their email before accessing the system
Password Security
Passwords are properly hashed and reset functionality works
