I will build a java spring boot backend and rest API


About this gig
Need a backend that's secure, fast and ready for real users? I'll build your Java Spring Boot backend and REST API from scratch, or fix and extend the one you already have.
I build and maintain the backend of a live payments platform in Kenya that handles real money every day: wallets, M-Pesa STK Push and payouts, card payments, webhooks, ticketing and accounting. I bring the same production standards to your project.
What I can build:
- REST APIs for mobile apps and websites
- Login, roles and permissions with JWT
- Payment gateways: M-Pesa, Paystack, Stripe, PayPal, Flutterwave
- Webhooks, scheduled jobs, emails, SMS and WhatsApp notifications
- PostgreSQL or MySQL databases with clean migrations
- Deployment to Render, a VPS or the cloud
You get:
- Clean, well-structured code
- API documentation (Swagger)
- Full source code
- Clear updates while I work
Message me before ordering so we can agree the scope.

FAQ
Can you work on my existing Spring Boot project?
Yes. Share the code and I'll review it, then fix bugs, add features or improve performance.
Which databases do you use?
Mostly PostgreSQL and MySQL. Database changes are managed with migrations, so updates are safe.
Will you deploy it?
Deployment is included in the Premium package and is an extra for the others. I can deploy to Render, a VPS or the cloud.
