Spring Boot Jobs

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 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 contract...

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...

The application is in active development with Java + Spring Boot on the server side and an Angular front end already taking shape. The next milestone is completing the “Software Development Team member” module, and the work centres on solid, well-tested backend logic. Consultant should have between 2 to 4 years of experience in above technologies What has to happen: • Design and implement Spring Boot REST endpoints that cover the full lifecycle of this module’s data. • Hook the endpoints to the existing persistence layer and ensure clean JSON contracts for the Angular client.

I’m building a web-based Java application that performs intensive data processing while talking seamlessly to our database layer, several third-party APIs, and existing internal enterprise systems. The goal is a single, cohesive platform that ingests raw data from multiple sources, transforms it, and presents the results through a clean browser interface. Core expectations • A robust Java processing engine capable of scheduling, prioritising, and tracking data jobs. • A responsive web UI (desktop and mobile friendly) that lets end-users launch tasks, monitor progress, and download results. • Connectors for relational databases, REST/SOAP APIs, and our on-prem enterprise services, with clear configuration files so new endpoints can be added without code changes. ...

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...

I’m expanding my Brazil-based development team and need a proactive, self-driven full-stack engineer who can own features from back end to mobile front end. You’ll be coding daily in Node.js, Java (Spring Boot), React Native, and Angular, with a special emphasis on using AI assistants such as GitHub Copilot or Claude Code to accelerate delivery without sacrificing quality or best practices. Most of our Node.js work powers mobile applications, so familiarity with building and scaling APIs for that environment is essential. You will collaborate through daily video stand-ups, push clean, well-tested code to Git, and help shape architecture decisions as we iterate. What I value: • Solid command of the full listed stack • Demonstrated ability to generate and refine cod...

I’m planning a single hub that lets our users sign in once and reach three core suites—CRM systems, Accounting software, and Project management tools—through a hybrid mobile app and complementary web portal. The entire experience should follow Material Design so the look and feel stay consistent across Android, iOS, and the browser. Core scope • Single sign-on that authenticates across every connected product • Home dashboard that surfaces active subscriptions and licence counts at a glance • Full subscription, licence, plan payment, and renewal workflows • Invoice history tied to each user account • Real-time and in-app notifications • Robust admin console to manage users, plans, and granular access rights • Sales dashboa...

I need a full-stack solution that covers two fully connected areas: Dealership Panel • Vehicle inventory must handle stock tracking, trigger automated low-inventory alerts, and let me export detailed reports. • Bookings, test-drive scheduling, a sales pipeline with customer follow-up, and appraisal workflows all sit in the same dashboard. Public Portal (think ) • Shoppers should be able to filter by price range, vehicle type, and brand/model, then compare results side-by-side. • Each listing shows vehicle history, a rich photo gallery, and transparent pricing. • Visitors can book a test drive online, open a chat with the seller, and run financing simulations without leaving the site. Technical preferences Backend in Java (Spring Boot is ideal) and mo...

I want to commission an end-to-end real-estate platform split into two tightly integrated areas: an Agency Panel and a consumer-facing Public Portal. Agency Panel The back-office must let each agency manage its entire catalogue with fully customisable property fields. Client follow-up tools are essential: I expect a sales pipeline, timeline notes, and reminders that I can filter by stage. Automatic export to external portals such as Idealista and Fotocasa is a must. Calendar-based appointment scheduling, an internal chat between agents and leads, and multi-agency support (each with its own branding, colours and domain) round out the requirement. Public Portal On the front end the visitor experience should mirror sites like Idealista. Core interactions I need are: • property li...

I’m planning a full-feature classifieds platform—web and mobile—modeled after Milanuncios or MercadoLibre. Core modules include dynamic ad publishing with unlimited categories and sub-categories; an advanced search that lets users filter by price range, location, and category and view results on an interactive map; real-time buyer–seller chat; plus a user rating/reputation engine. On the commerce side I need a shopping cart, international payment-gateway checkout, and workflow for orders, shipping, and returns. The back-office must let Administrators, Moderators, and Customer support staff manage users, ads, and editorial content from a single dashboard. Preferred stack: Java for the backend (Spring Boot or similar) and Flutter for the iOS/Android apps, but I&rsqu...

I’m starting a green-field product and need someone who is equally comfortable crafting a solid Java/Spring Boot/Hibernate back-end while shaping a clean, responsive Angular front-end. The goal is to deliver an entirely new application, not to patch an old one, so you’ll have room to make architectural decisions and set up best practices from day one. What the stack looks like • Back-end: Java 17, Spring Boot, Hibernate, Gradle/Maven • Database: PostgreSQL (already provisioned) • Front-end: Angular is mandatory; React skills are welcome for any future companion modules. Key pieces of the job • Design the initial domain model, RESTful APIs and security layers. • Build the Angular UI in parallel, wiring it to those endpoints as they solidify...
