What you get with this Offer
I will deliver a complete, production-ready Java backend system — from architecture design through development, testing, security hardening, and cloud deployment — built on Spring Boot with a clean, scalable architecture your team can maintain and extend as your product grows. This is a full backend engagement covering every layer from database schema to API contract, designed for businesses that need a professional Java system built correctly the first time rather than a prototype that requires immediate rebuilding.
The engagement covers system architecture design with ERD and API contract documentation, multi-module Spring Boot application development, Spring Security with OAuth2 or JWT authentication, Spring Data JPA with Flyway migrations, Redis caching layer, RabbitMQ or Kafka integration for async processing where required, comprehensive test suite (unit, integration, and contract tests), Dockerfile and Kubernetes deployment manifests, CI/CD pipeline, AWS or GCP deployment, API documentation with Swagger/OpenAPI, and a technical handover session with your development team. A 7-day post-deployment support window is included.
This service is designed for startups and scale-ups building a Java-powered product backend, replacing a legacy system, or extracting backend services from a monolith — who want a single experienced Java architect and developer to own the full backend delivery.

What the Freelancer needs to start the work
Please share your system requirements (what it does, key entities, user roles, expected load), your preferred cloud provider, Java version, authentication requirements, any external APIs to integrate, your target launch date, and your development team's Java experience level for handover planning. A discovery call is the first step before any architecture or development begins.
