Looks Like This Service Is On Hold
I will develop a saas web application using mern stack react and node js
Zayn Ali
About this gig
Turn your SaaS idea into a real, working product.
I build complete SaaS platforms using the MERN stack from your first MVP
to a fully-featured multi-tier subscription product. I recently architected
SignalPro, a SaaS trading-signals platform with 4 subscription tiers
($29$199/month), 5 admin modules, and 15+ REST API endpoints all
secured with JWT, bcrypt, and rate limiting.
WHAT'S INCLUDED IN MY SAAS BUILDS:
Multi-tier subscription logic (Free/Basic/Pro/Enterprise style plans)
Payment integration Stripe, JazzCash, or Easypaisa
Admin dashboard for managing users, plans, and analytics
Secure authentication (JWT, bcrypt password hashing)
Role-based access control (Admin / User / Team roles)
Automated jobs (cron-based limits, renewals, usage tracking)
Scalable MongoDB schema design with aggregation pipelines
Rate limiting & API security hardening (Helmet, express-rate-limit)
Cloud deployment (Render/Vercel) with environment config
WHY FOUNDERS CHOOSE ME:
- I understand SaaS-specific problems: churn logic, usage limits,
tiered access not just generic CRUD apps
- I've built and shipped a real subscription SaaS product end-to-end

FAQ
Can you integrate Stripe/JazzCash/Easypaisa for my region?
I've integrated Stripe, JazzCash, and Easypaisa in past projects and can advise which fits your target market.
I only have an idea, no technical spec — can you still help?
Send me your idea and target users; I'll help scope the MVP features and suggest a suitable package.
Will the platform be able to scale if I get more users later?
I design the database schema and API structure with scalability in mind from day one, not as an afterthought.
Do you handle recurring billing logic?
Yes, including plan upgrades/downgrades, renewal cycles, and usage-based limits tied to each tier.
Is hosting/server cost included in the price?
No, gig price covers development only. I'll help you choose a cost-effective hosting plan (Render/Vercel/VPS).
Can you continue as a long-term developer after the MVP is delivered?
Yes, happy to discuss an ongoing maintenance/development arrangement after delivery.
