Giovanni Lopez
About this gig
Expert Java Spring Boot Backend Development
I engineer high-performance, scalable REST APIs using Java and the Spring Boot framework. My focus is on clean architecture, secure data handling, and robust database integration for enterprise-level applications.
Core Technical Services:
- REST API Development: Custom endpoint creation (CRUD operations) following strict RESTful principles.
- Database Integration: Relational database mapping using Spring Data JPA and Hibernate (PostgreSQL, MySQL).
- Security Implementation: Securing endpoints using Spring Security and stateless JWT authentication.
- 3rd-Party Integrations: Consuming external REST APIs and connecting with microservices.
- Documentation & Deployment: Swagger/OpenAPI documentation setup and Docker containerization.
Supported Tech Stack:
- Java 17+ / Spring Boot 3+
- Spring Data JPA / Hibernate
- PostgreSQL / MySQL
- Spring Security / JWT
- Docker / Maven
CRITICAL REQUIREMENT: Do NOT place an order without messaging me first. Backend architecture requires precise scope definition. Contact me with your technical requirements so we can define the database schema, pricing, and exact delivery timeline.

FAQ
What databases do you support for the REST API?
I primarily work with relational databases like PostgreSQL and MySQL, integrating them via Spring Data JPA and Hibernate.
Do you also build the frontend (React, Angular, Vue)?
No. This Gig is strictly for backend architecture and REST API development. I will deliver the secure endpoints and documentation (Swagger) for your frontend team to consume.
How will you deliver the final code?
I will deliver the complete source code via a Git repository or a .zip file. If you purchase the Docker extra, I will include the Dockerfile and docker-compose.yml for easy deployment.
Can you fix bugs or add features to my existing Spring Boot project?
Yes, but please message me first. I need to review your current source code and architecture before you place an order to ensure an accurate quote.
