Project details
Launching a new SaaS platform? Setting up database isolation, tenant-specific routing, and secure authentication is the most critical technical step. I will design and build a rock-solid, secure, and scalable multi-tenant foundation for your Next.js and Node.js app.
What we can cover and build:
Database Multi-Tenancy: Configuring secure data isolation (logical separation via tenant IDs or separate schemas) using PostgreSQL/Prisma or MongoDB.
Advanced Authentication: Setting up multi-tenant organization login, role-based access control (RBAC), and user session security
Dynamic Subdomains: Configuring Next.js middleware to handle workspace routing (e.g., tenant1.yoursaas.com).
What you get:
Scalable boilerplate code for your Node.js backend and Next.js frontend app.
Secure database connection handling and user authorization middleware scripts.
Complete environment configuration guide for easy staging and production deployment.
Don't let technical debt ruin your SaaS launch. Get a clean, professional architecture built by a senior engineer. Order now to get started!

Create app to record audio and send to backend service (.Net Maui)
The work was excellent. Both from a technical as from a functional point of view.
I will surely use their services again when needed!

Senior Full-Stack Developer | Marketplace & SaaS (React/Node/Next.js)

Job Success
Kharkiv, Ukraine - 8:40 pm local time
I’m Oleksandr, a Senior Full Stack Developer focused on building SaaS platforms, marketplaces, and business applications with React, Next.js, and Node.js.
Most of my work is centered around products with complex workflows, payments, dashboards, role-based systems, and scalable backend architecture. I work closely with startups and growing teams to take products from early planning stages to stable production systems used by real customers.
I’m comfortable handling both frontend and backend development, improving existing codebases, and building new features with long-term scalability in mind.
Some of the platforms I’ve worked on include property management systems, booking marketplaces, operations dashboards, eCommerce platforms, and subscription-based products.
🚀 What I usually work on
✅ SaaS platforms and internal business systems
✅ Marketplace products with multi-role workflows
✅ Admin dashboards and operations tools
✅ Payments, subscriptions, and billing systems
✅ Booking and scheduling platforms
✅ API integrations and third-party services
✅ React Native companion apps
✅ Performance optimization and scaling
⚙️ Tech Stack
Frontend: React, Next.js, TypeScript, Redux
Backend: Node.js, Express.js, REST APIs
Database: PostgreSQL, MongoDB
Mobile: React Native, Firebase
Infrastructure: Docker, AWS, CI/CD
I care about writing maintainable code, keeping communication clear, and building products that are stable long-term, not just quick MVPs.
I’m also comfortable joining existing teams, working inside mature codebases, and helping improve architecture and development workflows when needed.
If you’re building a SaaS product, marketplace, or internal platform and need a developer who can take ownership of features from planning to production, feel free to reach out.
Steps for completing your project
After purchasing the project, send requirements so Oleksandr can start the project.
Delivery time starts when Oleksandr receives requirements from you.
Oleksandr works on your project following the steps below.
Revisions may occur after the delivery date.
SaaS Architecture & Tenant Strategy
We’ll review your SaaS structure, tenant model, authentication requirements, and scaling goals to define the best multi-tenant architecture for your platform, including database isolation, RBAC, and organization structure.
Backend Tenant Isolation & Security
I’ll implement secure tenant isolation in your Node.js backend, including middleware protection, tenant-aware APIs, access validation, and role/permission handling to prevent cross-tenant data exposure.
