You will get a scalable multi-tenant SaaS web app with React, Next.js and NestJS
Project details
I will build a custom, scalable multi-tenant SaaS web application for your business using React, Next.js, NestJS, TypeScript and PostgreSQL.
Your platform can include separate workspaces for each tenant, secure authentication, role-based dashboards, CRUD modules, API integrations, payment processing, real-time notifications, analytics and responsive user interfaces.
I can develop:
• Multi-tenant architecture with secure tenant data isolation
• Super admin, tenant admin, staff and customer roles
• React or Next.js dashboards and customer-facing portals
• NestJS REST APIs with validation and Swagger documentation
• Stripe payments, Connect payouts, subscriptions or refunds
• Socket.IO notifications, live updates or GPS tracking
• Google Maps, file uploads, email OTP and reporting
• Deployment-ready code with environment configuration
Before development, I will review your workflow and define a clear scope. Each package has fixed limits for screens, user roles, APIs and integrations. Complex marketplace, logistics or enterprise requirements can be handled through the Advanced package or a custom offer.

• AI chatbot and OpenAI API integration
• Python and FastAPI-based AI prototypes
• RAG chatbot development and AI/ML experimentation
I focus on writing clean, reusable, and maintainable code while ensuring that applications are responsive, secure, and optimized for performance.
Some of the results I have delivered include:
• Improved Lighthouse performance scores from 62 to 94+
• Reduced page-loading time by approximately 45%
