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!

Please structure the project so it can be deployed easily (Docker preferred, but I am open to other simple approaches) and include concise documentation; an OpenAPI/Swagger spec is ideal so the front-end team can plug in without guesswork. Deliverables • PostgreSQL schema (DDL) and seed data • REST endpoints covering create, read, update, delete for all defined entities • Environment and run instructions (e.g., Dockerfile or...

    I’m putting together a Wi-Fi light switch around the ESP32 and I need complete firmware plus a small, self-hosted web interface so the unit can sit on my network and drive a dimmable light circuit.

Key functions • Web interface (no mobile app requirement) served directly from the ESP32 • Features enabled: Scheduling, Dimming control, Remote access over the internet/LAN • Clean, responsive HTML + CSS + JavaScript (vanilla or lightweight framework) • MQTT support or lightweight REST endpoints are welcome if it simplifies remote control, but not mandatory Deliverables 1. Well-commented ESP32 source code r...

    I need a solid automation suite for my REST-based service and want it written in TypeScript with Cucumber. The API is already live; what’s missing is a reliable, repeatable way to validate each endpoint whenever we push new code. The job centres on building (or extending) a Cucumber + TypeScript framework that can: • hit every current REST endpoint, • assert responses and status codes, • pull test data from configurable files or environment variables, and • output readable reports (HTML or JSON) after each run. Once the core framework is in place, a handful of sample scenarios should demonstrate the pattern so my in-house team can keep adding tests. Clear setup instructions (npm scripts, ts-config, step definitions, feature files) and a brief README are es...

    I need a web-based marketplace where campaign creators can publish live campaigns and participants can join, submit their entries, and track their standing on a real-time leaderboard. The scope is mid-level: robust enough to handle multiple concurrent campaigns but still lean so we can launch quickly and iterate. Core flow • Campaign creators: register, build campaign pages, set rules/criteria, monitor submissions, and close or extend campaigns. • Participants: register, browse active campaigns, submit work (file upload or link), and see their rank on the leaderboard. • Leaderboard: auto-updates based on campaign-specific scoring logic I will provide. • Admin console: light moderation (approve/flag campaigns or submissions) and basic analytics. Tech expectatio...

    I need a straightforward Android application that lets diners open our restaurant’s menu instantly after scanning a table-side QR code. At this stage the app is purely for menu browsing—no ordering cart, no payment gateway—so the build can stay lean and focused on fast loading, clear category navigation, and an easy way for staff to keep dish names, photos, prices, and descriptions up to date. Here is what I’m expecting: • A clean Android APK (plus full source) that launches directly into a QR scanner and then displays the corresponding menu screen. • Menu data can live in any lightweight back-end you are comfortable with (Firebase, simple REST JSON or similar is fine) as long as content updates show in the app without having to publish a new build. ...
