You will get a Custom REST API built with Java Spring Boot and PostgreSQL
Project details
I provide production-ready REST API development using Java and Spring Boot, designed for scalability and security. As a Computer Engineer, I don't just write code—I architect robust backend systems that power modern web and mobile applications.
What I offer:
1. Scalable Architecture: Clean, maintainable code using Spring Boot and PostgreSQL.
2. Full Security: Implementation of JWT, OAuth2, and role-based access control to keep data safe.
3. Third-Party Integrations: Seamless connection with services like WhatsApp Business API, Stripe/Payment Gateways, and AI engines.
4. Performance Focused: Optimized database queries and efficient logic for high-traffic environments.
Whether you are building a new MVP or scaling an existing platform, I deliver documented, high-performance APIs that your frontend team will love.
