About this gig

Have a React or Node app that must serve multiple companies securely? I will convert it into a multi-tenant SaaS with organizations, isolated data, roles, and optional subscription billing.


I can implement:

Tenant and organization onboarding

Memberships, invitations, RBAC, and permissions

Tenant-scoped APIs, queries, jobs, files, and caches

Shared-database isolation and migration scripts

Stripe subscriptions, plans, limits, and webhooks

Super-admin controls, audit logs, and tenant settings

Isolation tests, documentation, and deployment


This service is for existing React, Next.js, Node.js, Express, or TypeScript apps using MongoDB or PostgreSQL.


Basic delivers an architecture and migration plan, not production code. Standard implements the tenant core in a small existing app. Premium adds launch-ready SaaS features within the stated limits.


Database-per-tenant designs, SSO or SAML, custom domains, white labeling, mobile apps, major redesigns, and large legacy systems need a custom offer. Before ordering Standard or Premium, please share your architecture, core data models, role matrix, billing needs, and deployment environment through Fiverr.

I help founders turn fragile prototypes and single-customer web apps into secure, maintainable SaaS products. My focus is React, Node.js, Express, TypeScript, MongoDB, PostgreSQL, authentication, Stripe billing, MCP integrations, API architecture, and multi-tenant systems. I can rescue AI generated apps, connect AI clients to business systems through secure MCP servers and convert existing products into organization based SaaS platforms with isolated data and rolebased access. My deliveries include source code, testing notes, clear documentation, and honest reporting of remaining risks.
