I’m launching an online store for physical goods and need a solid Java back-end with a well-documented API layer. The core of the project is user management—account creation, secure login, profile maintenance and order history—wired up to a credit/debit card gateway (Stripe, Braintree or a comparable processor, whichever you’re most comfortable integrating). All business logic should sit in clean, REST-friendly endpoints so any modern front-end can consume them later. Please structure the project with familiar Java tooling (Spring Boot or similar), include database schema scripts, and add clear README notes for local setup, build and deployment. Deliverables • Complete Java source code, organised and commented • REST endpoint documentation (Swagger or equivalent) • Working payment integration in test mode • SQL scripts and migration files • Brief hand-off session or screencast showing build, run and payment flow I value readable code, straightforward commits and prompt communication. If this sounds like your sweet spot, let’s get started.
