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:
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.

The product will be available on iOS and Android first, with a lightweight web dashboard for administration and analytics. Design I need a completely custom look and feel—no off-the-shelf Material or Flat themes. Your first task will be producing high-fidelity UI/UX mock-ups for the mobile apps and the web dashboard, then translating them into workable front-end components. Mobile prototype The prototype must run natively on both iOS and Android. It should already support: • Secure user authentication (email/social) • Push notifications (device token management included) • In-app purchases for digital content Backend & data layer Please archi...

I’m building FixIt, a mobile marketplace that instantly connects homeowners with vetted plumbers, electricians, carpenters and painters. I want a single code-base solution that ships clean, native experiences on both iOS and Android, so feel free to lean on Flutter, React Native or any comparable cross-platform stack you’re comfortable with.

I need a developer who already knows their way around ShipHero’s public GraphQL API to build a production-ready bridge between a retailer marketplace API (I’ll share credentials after kickoff) and our ShipHero account. The integration’s single purpose is to pull every new marketplace order in real time and push it into ShipHero with a clean order_create mutation so our 3PL team can fulfil inside ShipHero without manual touch points. Scope of the work You’ll handle the full flow: authenticate to ShipHero with bearer and refresh tokens, respect ShipHero rate limits, fetch the marketplace feed, translate each order’s customer information, order details and shipping instructions into ShipHero’s standard fields, then post with order_create. No custom field...
I’m expanding a set of business-critical automations and I need someone who already knows n8n inside out. You’ll take the lead on three fronts: • Designing and refining advanced workflow automation that can scale without breaking existing processes • Building custom nodes when the default palette can’t cover a requirement, keeping the code clean, documented, and merge-ready • Connecting n8n to a variety of external services—REST and GraphQL APIs, webhooks, and OAuth flows—so data moves seamlessly between our tools I’ll share a detailed mapping of each process, sample payloads, and access to a staging environment as soon as we start. Your work is considered complete when every workflow is running error-free in production, the custom n...
I’m building a cross-platform e-commerce sports mobile app and need a partner who is equally comfortable crafting polished UI/UX in Figma and wiring those screens to live APIs. The goal is one cohesive experience that feels native on both iOS and Android. First we’ll collaborate on user flows, then you’ll translate them into high-fidelity Figma frames and an interactive prototype I can test on device. Once the look and feel are approved, I’d like you to turn the designs into working code, connect every screen to our REST/GraphQL endpoints, and make sure checkout, product catalog, and account areas run smoothly and securely. Deliverables 1. Complete Figma file with design system, all screens, and a clickable prototype. 2. Source code for both platforms with API c...
I run a product-led SaaS company and need a full-stack engineer who can work the same hours I do—9 am – 5 pm Pacific Time, Monday through Friday. Every feature we ship is built with JavaScript from back to front, so daily work revolves around a Node.js/Express API layer feeding a React web application. You will own end-to-end development: refining tickets in our Monday morning grooming call, writing clean, well-tested Node services, and pushing pixel-perfect React components that match Figma specs. I deploy through a GitHub-driven CI/CD pipeline to AWS (ECS + RDS). Familiarity with GraphQL, PostgreSQL, Docker, and Jest is helpful, but solid Node.js fundamentals and modern React experience are the non-negotiables. Success is straightforward. By the end of each two-week spr...
I need a complete, production-ready website focused on community building. The core experience should let members create posts, share content in a scrolling feed, and interact in real-time through live chat rooms as well as smaller, interest-based groups or circles. A smooth onboarding flow, profile management, notifications, and a clean, mobile-first interface are essential. Beyond conversation, the platform must be flexible enough to add buying-and-selling features later, so structure the database and API with scalability in mind. Think modular components, reusable UI patterns, and clear separation between core community features and potential marketplace extensions. Tech stack is up to you, but I expect modern standards—responsive front-end (React, Vue, or similar), real-time ca...
Quiero que mis procesos internos funcionen solos gracias a n8n. El primer paso es conectar el flujo con nuestras herramientas de gestión de proyectos (Asana, Trello, Jira, Monday u otras que utilices con soltura) para que la creación de tareas, los cambios de estado, las asignaciones y las notificaciones se disparen de forma automática según las reglas que definiremos juntos. Dispongo de una instancia self-hosted de n8n y de las credenciales API necesarias. Tu trabajo consiste en diseñar los workflows, configurarlos, probarlos a fondo y dejarlos listos en producción. Busco además que documentes cada paso para que el equipo pueda darles mantenimiento sin depender de terceros. Entrego esquema de procesos y accesos de prueba; necesito de tu p...
I need a polished, production-ready frontend for an enterprise Network Operations Center platform. The stack is fixed: React with TypeScript, built through Vite and styled with Ant Design. The UI must surface complex monitoring data in four key ways: • Interactive graphs and charts for traffic, latency and device health • A real-time alerts panel that streams live incident data without page refresh • Clickable network-topology maps that let operators drill down from global to device view • A large-screen “command-center” dashboard that combines the above into an at-a-glance status board API endpoints for metrics and alert feeds are ready; your job is to wire them up, handle state cleanly, and keep performance snappy even at enterprise data volu...
I’m building a cloud-based SaaS solution dedicated to online retailers and need a seasoned developer to take the idea from concept to a working MVP. The platform must be multi-tenant, secure, and ready to scale, but above all it has to launch with three mission-critical e-commerce modules: • Inventory management – add, edit, track stock levels in real time. • Payment processing – integrate major gateways with PCI-compliant flows and webhooks for subscription or one-off billing. • Customer reviews & ratings – store, moderate, and display feedback with anti-spam safeguards. I’ll provide wireframes and UI style guides; you’re responsible for architecture, coding, testing, and deployment to a cloud provider of your choice (AWS, GCP,...
