I’m building a production-grade web application and need a seasoned full-stack Java developer to drive the effort from architecture through deployment. The back-end will be written in modern Java with Spring Boot at its core, using Hibernate for ORM and a microservices design to keep the codebase modular and scalable. You’ll own everything server-side: designing RESTful endpoints, modelling the database, securing the APIs, writing unit and integration tests, and containerising the services for smooth deployment. If you prefer bringing your own front-end stack, that’s fine—Angular experience is certainly welcome but not essential, as long as the UI integrates cleanly with the services you expose. When you respond, focus on the depth of your experience deliverin...

I’m planning a new website and want it built end-to-end with the tools I already trust—Java, Spring Boot on the server, ReactJS on the client, and either MySQL or MongoDB for persistence. The single non-negotiable feature is solid user authentication: registration, login, encrypted passwords, session/ token handling, and a clean path for future additions such as social-login or multi-factor. You will design the architecture, craft the REST APIs, wire the React front-end, and set up a responsive UI with clean HTML / CSS / JavaScript. Code should live in a GitHub repo with clear README, build scripts (Maven or Gradle), and environment files so I can stand it up locally or in the cloud without surprises. Please tell me about projects where you’ve delivered similar Java-Spr...

I’m building a responsive web application from the ground up and need a developer who can move comfortably across React + TypeScript on the front end and Java + Spring Boot on the back end. The core of the project is rock-solid user authentication and authorization: every screen and API call must respect three distinct roles—Admin, Seller, and Buyer—so granular permissions, session handling, and token refresh logic will be central to your work. What you’ll be working with • Front end: React 18, TypeScript, modern CSS and a component-driven approach that renders well on desktop and mobile. • Back end: Spring Boot, building REST endpoints that handle the auth flow, business logic, and data services. • Database: MySQL, with clean schema design and...

You’ll be taking charge of the server-side work for my application, and the core focus is clear: build a set of robust, well-documented RESTful APIs in Java. All persistence logic, request/response handling, and authentication layers will live in this codebase, so clean architecture and disciplined error handling matter a lot. Here’s what I expect to come out of this collaboration: • A modular Java codebase (Spring Boot or similar is fine) that exposes the required REST endpoints. • Well-structured data models mapped to the underlying database of your choice, with migrations/versioning in place. • Postman (or equivalent) collection and Swagger/OpenAPI documentation that let any front-end or third-party consumer hit the routes without guessing. • Unit...
