Spring Boot Jobs

I need a complete e-commerce website powered by WordPress and WooCommerce. The store must feel fast, modern, and mobile-friendly, with a clean product catalogue, smooth cart flow, and a secure checkout that runs through Stripe. Core expectations • Install and configure WordPress + WooCommerce on my hosting. • Customise a theme (your suggestion or a lightweight premium option I’ll purchase) so the look matches my brand colours and typography. • Set up product, category, and attribute templates so I can add items easily on my own. • Enable Stripe for payments, making sure test and live keys swap correctly and webhooks fire for order status updates. • Optimise page speed, image sizing, and caching so Core Web Vitals remain in the green. • Harde...

I'm looking for a US based freealncer, with at least 3 samples they can provide of similar projects done in the past. I’m launching a new online store and want the entire solution built with Java 17 and Spring Boot, structured as a “service-based monolith” that can be split into microservices later. The core modules should cover catalog, cart, checkout, user accounts, and order management, with clean REST APIs between them. We are open to improvements for the below requirements. Technology Stack: ● Frontend: React/ ● Backend: Java Spring Boot ● API Gateway: Kong or AWS API Gateway ● Databases: PostgreSQL + MongoDB ● Search Engine: Elasticsearch Cluster ● Message Queue: RabbitMQ or AWS SQS ● Cache: Redis Cluster ● Hosting: AWS (ECS/EKS) Core Services (7 Services): ...

I’m working on a Java Spring Boot micro-services application and need a seasoned hand to straighten out a few points and help me close some production Jira tickets. Most of my questions revolve around how the services talk to each other—specifically, how data moves between them in both synchronous calls (REST, gRPC or similar) and asynchronous flows (message queues, Kafka, etc.). I’d like you to walk me through the current interaction patterns, point out bottlenecks or anti-patterns, and suggest improvements. At the same time, I’ll share a small batch of Jira issues that are already reproduced in our lower environment. They typically involve cross-service data consistency or timing problems. Your role is to propose—and, if feasible within the scope, demo&m...

I’m putting together a small web application and need a solid email-and-password sign-in module. The tech stack is set: Java will drive the back-end, a compact C library (already written) handles our custom hashing routine, and the screens can stay simple with vanilla HTML/CSS. Here’s what I’m after: • Java endpoints for register, login, logout and session management, built with Spring Boot, plain Servlets or a framework you’re comfortable with. • JNI (or another clean bridge) that calls the provided C hashing library, with step-by-step build instructions. • Lightweight HTML pages—sign-up, sign-in, password reset—styled just enough to be readable. • Secure storage in MySQL or Postgres, using salted, hashed passwords. • ...

I need an experienced Java engineer to add a complete geofencing module to my existing Spring Boot backend. The core tasks are to detect enter, exit and dwell events in real time, expose the necessary REST endpoints and wire everything up to Google Maps API for geocoding and polygon handling. You will be working against a mature code-base that already manages users, devices and location pings. Your part is to design the geofence data model, build the event engine, and surface webhook or message-queue notifications that the rest of the platform can consume. Because this feature is a priority release, I would like to see it live as soon as possible ideally within the next couple of weeks. Please share relevant past work that proves you have shipped similar location-aware services, especial...

We’re building an Automation Control Plane that runs large-scale, cross-platform activity across multiple channels – tens of thousands of identities executing coordinated, daily actions from both Android emulators and headless browsers. The core backend already exists in Java/Spring Boot; your job is to turn it into a clean, scalable “one brain, many workers” platform and get it running in production fast. Today, we have a substantial Spring Boot application that knows about devices, sessions, users, and execution requests, plus a full suite of workflows (for one platform) automated via Appium. That code was originally written to drive physical Android phones in a device farm. We’re now moving to Android emulators on Ubuntu servers and need to stabilize and f...

I run a Java-based restaurant management application and need it to talk seamlessly to both Swiggy and Zomato so that staff never have to re-enter data in multiple dashboards. The scope is straightforward: connect to each partner API, pull menus, push updates, receive orders instantly, and track every delivery milestone without manual refreshes. Real-time event handling (webhooks or long-polling, whichever the platforms allow) is essential so that kitchen screens and POS reports stay in sync second-by-second. Please deliver: • Menu synchronisation: create, update and deactivate items and modifiers from my app and reflect those changes on Swiggy and Zomato. • Order management: ingest new orders automatically, send accept/cancel actions, print kitchen tickets, and post orde...

Voy a poner en marcha un ERP contable hecho a la medida y necesito que te encargues del desarrollo completo: Java en el backend, Angular en el frontend y PostgreSQL como base de datos. Todo el código debe quedar estructurado para crecer por micro-servicios más adelante, pero en esta fase se entrega como un solo proyecto bien desacoplado por capas. Cada uno de los módulos deberá ser totalmente personalizado —no partimos de plantillas ni de paquetes prefabricados— y compartir el mismo esquema de seguridad: registro e inicio de sesión con correo electrónico y contraseña, con roles gestionados desde la propia aplicación. Módulos que entran en esta primera iteración​ • Compras • Inventario • Produ...
