You will get A Secure SaaS Subscription Gating with Stripe, Node.js & Next.js
Project details
Most subscription gates fail quietly, checked only in the browser, easy to bypass with devtools, and impossible to trust at scale. This service builds server-side webhook verification tied to Stripe or Whop, so every protected route checks real subscription status against your database on each request, not just once at login.
I handle signature verification to stop spoofed webhook calls, database-synced access state so status updates in real time when a subscription is created, renewed, or canceled, and clean session logic that doesn't leave edge cases like expired trials or failed payments unhandled. Built using Node.js, JWT/OAuth 2.0, and production-grade REST API patterns, the same architecture used for multi-tenant SaaS billing systems.
Whether you're gating a course, a SaaS feature tier, a private community, or a downloadable tool, this locks it down properly instead of relying on client-side checks anyone can inspect and bypass.
I also handle grace periods, hard lockouts, and renewal edge cases so you're not fielding support tickets from confused paying users. Delivered with clear documentation on how the gate behaves so your team can maintain it without me.

Full Stack Developer Needed for SaaS Platform Development
Great working with Zubair. He maintained clear and consistent communication throughout the project and delivered the work on time. He has strong skills in React and Node.js and demonstrated good experience in SaaS application development. Zubair also has a solid understanding of database design and management, which helped ensure the system was well structured and scalable. Overall, a reliable developer, and I would definitely work with him again in the future. 👍
About Zubair
Full Stack AI Developer | Node.js, Next.js, Supabase | SaaS
Gilgit, Pakistan - 8:30 pm local time
I'm a Full Stack Developer specializing in SaaS platforms, AI-powered web apps, and production-grade APIs. I take projects from idea to production using Node.js, NestJS, Next.js, PostgreSQL, and TypeScript, handling architecture, backend systems, AI integration, and deployment end-to-end.
Here's what I've shipped as a Full Stack Developer:
✅ FloristHub: Live multi-vendor marketplace. Built the full Next.js frontend, real-time booking flow, and florist dashboard covering orders, availability, pricing, and messaging. In production today.
✅ Tourism Marketplace: 800,000+ active users. Full backend in Node.js and PostgreSQL, vendor management, booking flows, and payment integration built to handle real traffic from day one.
✅ HR Management System: Cut administrative workload by 60%. Automated workflows, role-based access control, and a reporting dashboard that replaced a manual, spreadsheet-based process.
As a Full Stack Developer, here's what I build:
⚡ SaaS Platforms: Full-stack builds with Next.js, NestJS, Node.js, and PostgreSQL. Multi-tenant SaaS architecture, Stripe subscription billing, role-based auth, and admin dashboards built for real scale.
⚡ AI Integration & Automation: OpenAI API and LangChain integrations, RAG pipelines, n8n automation workflows, and AI-powered backends that eliminate manual operations. I use Cursor, Claude Code, and modern AI tooling to ship faster without sacrificing quality.
⚡ APIs, Auth & Payments: Production-grade REST and GraphQL APIs, OAuth 2.0, JWT authentication, and Stripe payment systems. Secure, documented, and built to handle load from day one.
⚡ DevOps & Deployment: Docker, CI/CD pipelines, AWS, Vercel, and NGINX. Your app in production, not just running on localhost.
⚡ MVP Builds: Got an idea? As a Full Stack Developer I take you from wireframe to deployed MVP in weeks. Clean architecture your team can maintain and build on after launch.
How I work as a Full Stack Developer:
Before writing a line of code, I scope the project in writing, architecture, deliverables, timeline. You get regular updates, zero ghosting, and I flag problems early before they become blockers. The code I deliver is clean, maintainable, and production-ready.
I work best with startups, founders, and agencies who have a real problem to solve and need a Full Stack Developer who thinks beyond the ticket.
Message me with your project. I offer a free 30-minute discovery call, respond within a few hours, and I'll tell you upfront if I'm not the right fit.
Cheers,
Zubair A.
