You will get production-ready REST API with Java Spring Boot


Project details
I build clean, reliable REST APIs with Java and Spring Boot for web apps, mobile apps, internal tools, and system integrations.
Choose the package that fits your needs:
REST API Starter: 1 API resource with CRUD operations, validation, database integration, and organized source code.
Professional API: up to 3 API resources with business logic, error handling, database integration, basic security, and documentation.
Enterprise API: up to 6 API resources with Hexagonal Architecture, database design, security configuration, performance improvements, and API documentation.
My process includes requirements review, API design, development, testing, documentation, and delivery of the complete source code. I focus on clear communication, clean code, SOLID principles, and maintainable solutions.
Please contact me before ordering if you need deployment, cloud services, Docker, OAuth2, external integrations, legacy system changes, or additional endpoints.

About Egberto
Java Backend Developer | Spring Boot, REST APIs & PostgreSQL
Tocancipa, Colombia - 3:43 am local time
I specialize in Java, Spring Boot, PostgreSQL, REST APIs, microservices, JPA/Hibernate, clean code, and maintainable backend architectures.
In my current role, I develop and support REST APIs for financial applications, optimize PostgreSQL queries, solve production incidents, and improve existing business processes. I have reduced processing times by approximately 30% through database and backend optimizations.
I can help you with:
• Java and Spring Boot REST API development
• PostgreSQL query optimization
• Existing backend maintenance and bug fixing
• Business logic implementation
• Database integration
• JPA and Hibernate
• Unit testing with JUnit and Mockito
• Microservice improvements
• API integrations
• Clean and maintainable code
I value clear communication, realistic commitments, and solutions that are easy to maintain and extend.
I can work on new backend projects or review and improve an existing Java application
