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:
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.

I’m in the closing stretch of a .NET Core microservice project and need an extra set of experienced hands to get us over the line. The architecture is already in place and running in containers, but several new endpoints and service refinements still have to be coded, tested, and deployed. Your focus will be pure development inside the existing Dot net Core microservices: writing clean C# for REST endpoints and message-bus consumers, extending EF Core queries, and ensuring every change sails through our Git- and Jenkins-based CI/CD pipeline. Once the code is committed you’ll containerise it, update the Helm charts, trigger the build, and keep an eye on Kibana to confirm the logs are healthy. Gatling drives our load tests, so any change must survive that suite before we call it...

I have a mature JavaScript / Node.js codebase that now needs robust API connectivity. The goal is to wire in several external services—some exposed as classic REST endpoints, others as GraphQL—so the application can consume, transform, and surface that data seamlessly to the front-end. Here’s what I need from you: • Analyse the existing structure, identify the best touch-points for new service layers, and keep everything idiomatic to Node.js (Express, middleware, async/await). • Build out the integration layer for both REST and GraphQL calls, including token management, retries, and intelligent error handling. • Return clean, typed responses (TypeScript definitions or JSDoc) so downstream modules stay type-safe. • Write concise unit and integr...

I need an engineer who can wire up OneSignal push notifications end-to-end for my Lovable web app, which is wrapped as a native iOS build through Median. Users authenticate with email / password, Google, Apple and magic link; whichever method they choose, their Supabase UUID must become the external_user_id in OneSignal so that every notification targets the right person. On first launch the app should ask for all notification permissions in a single prompt, respecting Apple guidelines. From there the flow has to stay in sync with authentication: register the device on login, cleanly remove it on logout, and keep token changes in the background. I have built a custom panel in the admin backend which ties push notifications to site notifications, and also enables custom notifications to a...

We are looking for an experienced backend developer with strong knowledge of AWS (SES, S3, Lambda) and the Frappe Framework. We need to build an event-driven "push" architecture for incoming emails.

I need an app that lets travellers search for activities—sightseeing tours, adventure sports and unique local experiences—compare prices across multiple providers and then complete the booking inside the same interface. Direct, in-app payment and confirmation are essential, so the flow must stay within the app from discovery through checkout. To keep development efficient you’re free to choose the tech stack, but a modern, scalable approach (for example: React Native or Flutter on the front end, a lightweight Node or Python back end and REST / GraphQL APIs) will suit the job well. I’m open to using third-party activity suppliers such as Viator, GetYourGuide or Klook, provided the final build can pull real-time prices and availability from at least two data sources ...

You’ll handle both front-end and back-end coding, design a well-structured database, and set up CI/CD so each push automatically deploys to a staging environment. Deliverabl...

I’m building a secure, responsive web application that lets both mortgage brokers and loan applicants move a loan file from first enquiry to final approval without drowning in email threads or loose paperwork.

Your work should cover: 1. Secure OAuth or token-based authentication...
