You will get a secure REST API endpoint built in Go or Java
Rising Talent
Project details
I will build, improve or extend secure REST API functionality in Go or Java, following the architecture and coding conventions of your existing project.
Depending on the selected package, I can deliver one or more related endpoints with request validation, clear error handling, business logic, PostgreSQL integration, authentication or authorisation, automated tests and API documentation.
This service is suitable for:
• Creating new REST API endpoints
• Extending an existing backend feature
• Connecting endpoints to a database
• Adding validation and structured error responses
• Implementing authentication or access control
• Writing tests and API documentation
• Improving existing Go or Spring Boot backend code
Before development begins, I will review your requirements and confirm that the requested work fits the selected package. You will receive maintainable source code, clear communication and practical delivery notes.
Please contact me before ordering if the project has a complex legacy architecture, several external integrations or unclear requirements.
