I will develop a full stack web application with spring boot and react
Pternali
About this gig
Need a complete web application, frontend and backend working together, not just a demo?
AI tools can generate pieces of code fast, but assembling a real, working full stack application still requires engineering: solid architecture, secure APIs, a frontend that actually talks to your backend correctly, and a system that holds up with real users.
I'm a Full Stack Developer with 7+ years of experience in Java, Spring Boot, React, REST APIs, PostgreSQL, Docker and Kubernetes. At IBM, I worked on enterprise applications from requirements to production.
What you get:
- Complete web application: React frontend + Spring Boot backend
- Responsive design that works on desktop and mobile
- Secure authentication (JWT / Spring Security)
- Database integration and clean data models
- Fully commented, production-ready source code
Also great if:
- Your AI-generated app looks fine but breaks under real use
- You need frontend and backend properly connected and working together
- You're turning a prototype into a real product
Let's build a web application that's ready for real users, not just a proof of concept.
Message me before ordering if your project has specific requirements.

I’m a Backend & Full-Stack Web Developer with 7+ years of experience in Java, Spring Boot, React, REST APIs, Kafka, PostgreSQL, Docker and Kubernetes. At IBM, I worked on enterprise applications from requirements to production. I’ve built systems handling ~2,000 messages/sec with ~99.9% uptime.
AI can generate code. I bring what production software still needs: architecture, problem-solving, debugging, performance, reliability and sound engineering decisions. I use AI to move faster — while making sure the final product is actually solid.

FAQ
My app was mostly generated with AI tools but the frontend and backend don't work well together. Can you fix it?
Yes, this is a very common situation. I'll review both sides, identify where the integration breaks, and fix or rebuild what's needed so frontend and backend actually work together reliably.
Do you design the UI, or do I need to provide one?
I can build clean, functional interfaces from scratch, or follow a design you already have (Figma, Adobe XD, or reference screenshots). If you don't have a design yet, share your requirements and I'll propose a clean, modern layout.
What technologies do you use for the frontend and backend?
Backend: Java, Spring Boot, Spring Security, REST APIs, PostgreSQL, MySQL, MongoDB. Frontend: React. If your project needs something slightly different, message me before ordering.
Do I get full ownership of the source code?
Yes. Once the project is delivered and the order is complete, you own 100% of the code with no restrictions.
Can you work with my existing codebase instead of starting from scratch?
Absolutely. Share your repository before ordering so I can assess scope and give you an accurate timeline.
Do you handle hosting and deployment?
I deliver production-ready code and can containerize the app with Docker. Full deployment to your hosting provider can be arranged as part of a custom offer.
My project is bigger than what's listed in the packages. Can you still help?
Yes, I regularly build larger custom web applications. Send me your requirements and I'll put together a tailored offer.
