I will build and integrate secure java rest apis

Do you need a fast, well-designed API or to integrate an external service? I build it in Java (Spring Boot) with best practices and clear documentation.

What I do

REST API development from scratch

Third-party API integration (Stripe, Google, Twilio, Telegram, etc.)

OAuth2/JWT authentication, roles, and permissions

Validation, error handling, and webhooks

Logging, pagination, and filters

OpenAPI/Swagger + user guide (Postman)

JUnit testing and Docker-ready pipeline

What you get

Clean and commented code, organized repo

Stage delivery with demo and Postman collection

Basic: 1 endpoint or 1 simple integration

Standard: up to 3 endpoints + docs (no DB)

Premium: up to 5 endpoints + database (MySQL/SQLite via JPA) + tests

Process

Brief and endpoint definition

Rapid API contract design

Implementation and testing

Adjustments based on reviews

Client requirements

Desired endpoints, Sandbox credentials, sample payloads, target hosting (AWS/Azure/GCP/on-prem).

Optional extras: 24-hour delivery, more endpoints, Dockerfile/K8s, CI/CD.

Please write to me before ordering to confirm scope and timing.
