I will develop a full stack react and node js web application
Shivang Kumar
About this gig
Need a web application that actually works in production not just looks good in a demo?
I am a full-stack developer who has built and deployed real SaaS platforms used by thousands of users. GreenPathshala (LMS + CRM) and Scaleruby (WhatsApp SaaS) are two live products I built from scratch both running on React.js, Node.js, and PostgreSQL in production.
What I build for you:
- React.js frontend with Tailwind CSS fast, responsive, modern
- Node.js + Express.js REST API with proper error handling
- MySQL, MongoDB, or PostgreSQL database your choice
- Secure JWT authentication and role-based access control
- Admin dashboard with user and data management
- Docker-ready deployment I can deploy to your server
- Clean, documented code you can maintain and scale
I do not build template-based websites. Every project is custom-coded for your exact requirements.
Tech stack: React.js, Node.js, Express.js, TypeScript, MySQL, MongoDB, PostgreSQL, Docker, Redis
Message me your project brief before ordering. I will respond with a clear plan and timeline within 2 hours.

I am a full-stack developer specializing in WhatsApp Business API automation, SaaS platforms, and production-grade web applications. I built Scaleruby — a live WhatsApp automation SaaS used by real businesses for bulk messaging, CRM, and campaign management. I also built GreenPathshala, an LMS + CRM platform serving thousands of users. My stack: React.js, Node.js, TypeScript, PostgreSQL, Redis, Docker. I write real custom code — no no-code tools, no templates. Every system I deliver is scalable, documented, and fully owned by you.

FAQ
Can you build a full-stack MERN or PERN application with user login and dashboard?
Yes. I build complete applications with JWT authentication, role-based access control, and custom dashboards. Both MERN (MongoDB) and PERN (PostgreSQL) stacks are available depending on your project needs.
Do you have experience building SaaS or LMS platforms?
Yes. I have built two live SaaS platforms — an LMS with integrated CRM (GreenPathshala) and a WhatsApp automation platform (Scaleruby). Both are in production and used by real clients.
Will I get the source code after the project is delivered?
Yes. You receive full source code, a GitHub repository handover, basic documentation, and deployment instructions. I never use proprietary frameworks that lock you in.
Can you integrate payment gateways like Razorpay or Stripe into the web app?
Yes. Payment gateway integration (Razorpay, Stripe, or PayPal) is available as an add-on. Message me before ordering and I will include it in a custom quote.
How do you handle project communication and progress updates?
I send updates at key milestones — after UI setup, after API completion, and before final delivery. I respond to messages within 1–2 hours during working hours.
