GraphQL is a powerful technology that makes it easy for clients to build more efficient applications. GraphQL was developed as a way to deal with the bad scalability of traditional RESTful API. GraphQL helps clients create data-driven interfaces that work faster and more efficiently while they allow the development team to ask for their data in a more structured way. It is an open source query language made specifically for frontend and backend engineers to improve the way data is requested and delivered.

A GraphQL Developer can create complex, real-time, data-driven frontend interfaces by providing clients with fast and efficient access to the back end data. The GraphQL developer can also help increase the performance of applications by optimizing the requests sent over networks, while they provide additional protections from possible intrusions.

Here's some projects that our expert GraphQL Developer made real:

  • Built APIs to handle large amounts of data for clients
  • Developed applications with in-depth query capabilities
  • Created efficient web applications built with GraphQL, NodeJS and React
  • Created custom scalability solutions to make sure data is constantly updated in real time
  • Improved overall performance of applications

GraphQL developers have the tools and knowledge necessary to create powerful and reliable applications that are both cost effective and optimally performant. These developers can provide various solutions custom tailored to specific client needs, as well as help integrate new technologies quickly and safely into existing infrastructure.

If you're looking for a fast, efficient, and secure way of developing your application, our experienced GraphQL developers can help make it happen. Let our experts power your project from start to finish – post your project now on Freelancer.com, hire experienced professionals and get your project completed quickly!

    I need a full-stack developer who can deliver a visually striking, futuristic AI website that bundles three core services in one place: machine learning model development, data analysis services, chatbot integration, agents dev, app dev, website dev, etc and many more. The interface must feel ahead of its time—sleek motion effects, bold gradients, subtle micro-animations, and crisp typography that immediately signal “AI innovation”. A multi-step, automated request form will sit at the heart of the site. When a potential client clicks “Start Project”, the form should dynamically collect every detail I need—images and diagrams, Figma files, and inventory sheets—before routing the completed brief to me by email (and storing it in the database).

    I am assembling a new loan-processing platform and need a seasoned Node.js developer to stand up the entire backend. The core of the job is to architect and code secure user authentication and authorization, handle the full life-cycle of a loan application form, and build reliable payment processing with clear tracking of every transaction and status change. For data persistence I would like you to work with a SQL database—MySQL or PostgreSQL are both fine—so please structure your models and migrations accordingly. Beyond our own data store, the service must connect smoothly to several third-party providers: a credit-score API to pull applicant scores in real time, a payment gateway for disbursements and repayments, and notification services that let us push SMS and email upda...

    I’m creating an online destination where soccer enthusiasts can check reliable, data-driven match predictions before every kick-off. The engine behind the site will combine large sets of historical match data with up-to-the-minute season statistics, feeding them into a machine-learning model that outputs win-draw-loss probabilities and scoreline estimates. What I need from you is the full build: model selection or custom architecture, data-pipeline automation that fetches and refreshes both the historical archive and the current-season feeds, and a clean web interface that presents predictions in an easy, fan-friendly format. Odds-style percentages, form graphs, and key player influences should surface prominently so visitors can grasp the rationale behind each forecast without re...

    I need a developer who can connect the AGDC (PM USA) scan-data feed with the R.J. Reynolds loyalty program and have both flow cleanly into my existing CRM and e-commerce platform. The aim is to streamline day-to-day operations by keeping customer information, transaction details, and loyalty points perfectly in sync—no manual exports, no batch uploads, just real-time accuracy. Here is the workflow I’m picturing: when a customer purchase is scanned, the data should automatically populate our CRM record, update loyalty balances in the RJR program, and reflect the same information on the storefront side of the e-commerce system. Any change in one system must instantly show up in the others. I’m open to the underlying mechanics—REST or GraphQL APIs, middleware like Zap...

    I have a small iOS / Android app that was built years ago and never truly launched. The code still compiles, yet everything—from the visuals to the underlying logic—feels frozen in time. I now run an up-to-date website and I’m ready to bring the mobile experience in line with it. Here is what I need: • Refresh the full app • Introduce modern AI-driven capabilities where they make sense (for example, personalised recommendations and smart search). • Update all workflows and data handling to satisfy today’s regulatory requirements in our sector. • Ensure design, navigation and interactive elements look and behave like the site, using current iOS and Material guidelines. • Optimise performance and codebase for the latest OS versions,...

    I’m building out a new React front-end and now need the server side to catch up. The priority is a robust Node.js backend that exposes well-structured RESTful endpoints returning clean, predictable JSON. The data layer will live in MySQL, so you’ll design the schema, set up migrations, and write queries or use an ORM—whichever keeps performance high and code readable. Although Laravel experience is welcome and I do plan to introduce a small GraphQL layer later, right now your main focus will be the REST API: authentication (token-based), role management, pagination, filtering, and solid error handling. Clear inline documentation and a concise README or Swagger / OpenAPI file should accompany each route so the React team can plug in immediately. I’m flexible on tim...

    I’m setting up a new mobile application and have chosen Flutter so the same codebase can launch on both iOS and Android without compromise. The core concept and feature set are outlined; what’s missing is the hands-on Flutter expertise to turn those ideas into a polished, production-ready app that runs smoothly on each platform. All visuals, navigation flow, and user stories are ready for implementation. I’m flexible on the server side—we can plug into an existing REST/GraphQL service, stand up a fresh custom backend, or lean on a third-party solution if it speeds up delivery. The priority is clean, well-structured Dart code, an intuitive UI that follows Cupertino / Material guidelines, and reliable performance on recent iOS and Android versions. Deliverables &b...
