You will get a full stack web app with java spring boot and react


Project details
Need a production-ready web application, not a fragile prototype?
I'm a backend engineer with 4+ years of experience building fintech and trading platforms serving 100K+ users and I bring that same production discipline to full stack projects.
What you get:
Secure REST API built with Java Spring Boot (JWT / OAuth 2.0 authentication)
Modern, responsive React frontend
PostgreSQL database with clean schema design
Payment integration (Razorpay / Stripe) if needed
Clean, documented source code with deployment support
Why me over a generic full stack developer?
I've built real payment systems, real-time data pipelines, and PCI-DSS compliant services in production. Your app won't just work in a demo it will hold up under real users.
Perfect for:
SaaS MVPs and startup products
Business dashboards and admin panels
Web apps with payments and user accounts
Please message me before ordering so we can scope your project and I can give you an accurate timeline.
Let's build something that lasts!
