...stack: business logic may be shared between Scala (preferred for the new modules) and existing Java components, so the codebase must compile seamlessly with sbt/Maven and run on the latest OpenJDK. • Database: the service talks exclusively to a SQL engine (PostgreSQL in staging, MySQL in legacy environments). Expect schema versioning through Flyway and data access via Slick or standard JPA/Hibernate—whichever is lighter for the task. • Requirements: endpoints must follow REST conventions, include Swagger/OpenAPI docs, handle pagination, validation, logging, and return proper HTTP status codes. • Non-functional: unit and integration tests in ScalaTest/JUnit, Dockerised build, and CI‐ready scripts are all part of the definition of done.

I’m looking for a Java developer who can turn my existing MySQL schema for a Student Management System into a fully-functional REST service. The project must be built with Spring Boot, Hibernate/JPA, and Maven, exposing clear CRUD endpoints for students, courses, and any linking entities already defined in the schema. Security is required: please wire in both authentication and role-based authorization using straightforward Basic Authentication so the code remains beginner-friendly while still demonstrating best practice. Global exception handling, meaningful HTTP status codes, and neatly layered architecture (controller-service-repository) are all expected. I will supply the schema up front, so there’s no data-model design work—focus on implementing it clean...

...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 delivering similar Spring, Spring Boot, Hibernate or microservice-based projects in a live environment. I value clear...

I’m setting up a series of REST services built on Java 17 with Spring Boot and need an experienced backend developer to take ownership of both new features and ongoing maintenance. The core of the work is writing clean, test-covered code that exposes reliable, versioned endpoints, backed by a MySQL data store accessed through JDBC and, where appropriate, JPA/Hibernate. All modules sit in a microservice architecture and are managed through Git, so solid branching and pull-request discipline is essential. While the focus is the backend, it will help if you can speak the same language as our UI team; they primarily work in React and Angular with plenty of vanilla JavaScript, HTML, CSS, Bootstrap—and the occasional PHP snippet for legacy views—so being able to align c...

I need an experienced Java developer to take full ownership of the backend layer for a rapidly-growing application. The stack is Spring Boot with JPA / Hibernate, running against a PostgreSQL database, and every feature you build must expose clean, well-documented REST endpoints. Your first objective is to design and implement user-management services: sign-up, authentication, role-based authorisation, profile update and password recovery. The code base already follows a clean-architecture layout and I maintain a detailed coding-standard document that covers packaging, naming, exception hierarchy, logging levels, test coverage and performance budgets; you will be expected to align with it from day one.

A partially built micro-service still needs a set of REST APIs finished. The codebase already runs on Spring Boot, so the work focuses on extending it with three concrete capabilities: • User authentication and authorization – Spring Security (JWT) is preferred so tokens can be issued and validated across services. • Data retrieval and storage – CRUD endpoints must persist through JPA/Hibernate to the existing MySQL instance (schema and credentials will be provided). • Third-party service integration – one external REST service (simple JSON over HTTPS) has to be consumed and its response mapped into our own domain model. Deliverables expected: 1. Clean, commented Java code inside a Maven/Gradle module that compiles and starts with the res...

...development phase. The core of the service is written in robust Core Java, with Spring Framework (largely Spring Boot) orchestrating each microservice and Hibernate handling ORM. Your role is to take ownership of individual services: designing the endpoints, wiring Spring components, integrating the Hibernate entities, and then pushing clean, tested code into our Git repo. We hold short onsite sync-ups once or twice a week, so being locally available is essential, but you’ll otherwise work remotely on your own schedule. If you’re comfortable slicing a user story into small, testable tasks, writing clean Java 17 code, and troubleshooting Spring/Hibernate quirks without drama, we should talk. Deliverables will be accepted when: • Each assigned mic...
