REST APIs are the interface between clients and servers that allows for data to be shared across platforms, providing a seamless connection between applications, databases, and other resources. A REST API Developer is the programmer who helps clients connect their applications to a certain platform and ensure data is flowing between the two in an efficient, secure manner. This can help to reduce friction, improve performance & scalability, boost security, streamline website navigation, and more.

REST API Developers build and maintain custom programming to enable automated data retrieval and communication with a client’s desired application or platform. This can encompass services such as quickly integrating third-party payment systems into an existing website, minimizing manual work and improving customer experience. They may also incorporate priority systems; for example creating different APIs for handling bulk vs single requests for heavy workloads. Ultimately a REST API Developer helps clients bridge the gap between complex platforms and transform data into valuable business insights.

Here’s some projects that our expert REST API Developers made real:

  • Establishing communication between different applications
  • Creating priority systems for managing large volumes of requests
  • Integrating third-party payment systems into an existing website
  • Developing programming to seamlessly retrieve dynamic data
  • Designing secure connections to protect confidential information

Our highly-skilled REST API Developers are experts when it comes to stitching together the critical links which connect disparate platforms together. With years of experience they have been able to tackle innumerable projects which have led to successful outcomes for our clients. If you have an issue related to connecting your application with another platform or require automated data retrieval services then you can post your own project here on Freelancer.com and hire one of our experienced developers today!

    I need a production-ready RESTful backend built with Java Spring Boot that covers the full user lifecycle. Authentication must rely on Spring Security with JWT tokens, supporting two clear roles—Admin and regular user. Once signed in, both roles should access endpoints protected by role-based authorization rules. The API must expose the complete CRUD suite (Create, Read, Update, Delete) and persist everything in a MySQL database that stores user information and roles. Please model the schema so it can be expanded later without data migrations. Clean, readable code is essential: follow SOLID, layer the project (controller, service, repository), and annotate everything with Swagger / OpenAPI so I can explore endpoints instantly. Every business method should be covered by unit tests...

    I’m setting up a new e-commerce platform and want it architected as a collection of microservices. The core service I need first is a rock-solid Product Catalog: searchable, filterable, and ready to scale as the inventory grows. That means designing its own database schema, APIs, and admin endpoints while keeping the door open for companion services such as user authentication and a payment gateway that I may plug in later. Here’s how I picture the engagement: • You define the microservice structure, select appropriate tech (Node.js, Spring Boot, or another framework you’re comfortable with), and spin up a clean, container-ready codebase. • The Product Catalog must expose REST/GraphQL endpoints, handle basic CRUD plus bulk import/export, and support SKU-l...

Day-to-day you’ll code functional React components, manage state, talk to REST APIs, and push your work through Git. I’ll pair you with senior engineers for reviews and architecture discussions so you get fast feedback and exposure to production-grade patterns. When UI/UX tweaks are needed, you’ll work closely with our designer to translate Figma frames into responsive, accessible layouts. Deliverables that will mark your progress: • A commit set ea...

    I’m ready to build a full-stack intercity cab solution and need a team that can deliver four tightly-integrated components: 1. Driver App (Android) • Drivers receive trip notifications with all ride details the moment a dispatch manager assigns a job. • Built-in navigation must optimise routes dynamically, taking toll plazas and state borders into account so the fare calculator can add toll tax, state tax and (where relevant) airport parking in real time. • A clean earnings dashboard should let drivers track daily, weekly and monthly payouts and drill into Razorpay / Paytm settlement history. 2. Rider App (Android & iOS) • Passengers can book or schedule rides ahead of time, pick vehicle category and view an upfront cost that already i...

    I need a detail-oriented tester who can move comfortably between hands-on manual checks, structured API exercises, and careful data entry while I finalise a USSD menu for release. The core goal is data accuracy: every figure pulled from, written to, or displayed by the system must be proven correct. Here is how the work breaks down. • Web and desktop builds of the product both require functional sweeps. You will follow existing user stories, expand on them where gaps appear, and record every deviation in a concise bug report. • Our REST endpoints need repeatable validation. Feel free to use Postman, JMeter, or another tool you prefer, but make sure assertions cover all status codes, payload structures, and edge-case parameters. • During each round of testing you will e...
