API Development is an effective way for software to communicate and interact with each other over the internet. It’s a great way for developers to expand the capabilities of a program or systems by creating interfaces and allow data to be shared between different types of technology. With an API, existing systems can connect and more advanced solutions can be made. Hiring an API Developer can enable businesses to streamline processes and enable a much faster integration of existing software solutions.

API Developers are skilled engineers specialized in creating new APIs and maintaining existing ones. They are responsible for developing and troubleshooting current APIs, designing APIs from standards-based web services, maintaining inventory and implementing authorization mechanisms. Additionally, they incorporate different technologies together to create advanced software solutions that integrate cloud systems like Amazon Web Services or MongoDB and APIs with point-and-click platforms, like WordPress or HubSpot.

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

  • Creating advanced databases on different cloud systems
  • Linking between two cameras from a microscope
  • Interfacing with customizing Wordpress themes, Woocommerce themes and SMS services
  • Building secure back end systems to analyze different public APIs
  • Applying sophisticated authorization mechanisms
  • Creating comprehensive ecommerce websites using MERN Stack
  • Developing node APIs for exchange markets using Node.js, Web3.js, Ether.js
  • Automatically out of stocking items from supplier’s stock through an API system.

It is no surprise that good API Development is the cornerstone of many successful software solutions. Our expert API Developers are well experienced in developing suitable solutions for projects ranging from app development to SaaS applications, game development to enterprise system integrations. WithFreelancer.com, businesses can easily hire one of these skilled professionals to build their own bespoke projects that are perfectly tailored for their needs. So why not post your own project on Freelancer today and hire an expert API Developer?

Here’s what I’m trying to achieve: • Stabilise GPT-3 responses so they never output clinically inaccurate information again.

Here’s what success looks like to me: • Every API endpoint returns consistent, correct responses with proper error handling. • Average response time and CPU usage drop to an acceptable threshold agreed during kickoff. • All fixes are covered by automated tests (PHPUnit for Laravel, `go test` where you touch Go code) and pass in CI. • A concise changelog explains the root cause and remediation steps so ...

    I’m putting together a courier tracking system for our Lion Parcel kurir operation and the priority right now is clear, reliable access to historical delivery data. Every parcel scan—pickup, transit, attempted drop-off, completion—needs to be captured, stored, and then surfaced through a web-based dashboard that’s quick to search, filter, and export. The core of the job is therefore twofold: • build or connect an API layer that ingests our existing scan events and stores them in a tidy, query-friendly structure, and • design a responsive web dashboard where authorised staff can log in, choose a date range, filter by AWB, courier, hub, or status, and instantly see the journey summary in table or chart form (CSV/PDF export included). Real-time maps...

    I need a seasoned reverse engineer who can take a deep dive into a particular video-streaming site and return with a clear, thorough explanation of how it actually works. While I want the full end-to-end picture, my main curiosity lies in the video-player layer—specifically how it performs AI-based upscaling during playback. Here is what I expect you to uncover and document: • Front-end stack in use and any frameworks that stand out. • Detailed breakdown of the video player itself—controls, custom scripts, third-party libraries, and, most importantly, the AI upscaling workflow (models employed, in-browser processing vs. server-side inference, adaptive behaviour, fall-backs). • Exact video delivery approach: HLS, DASH, WebRTC, peer-assist, or any hybrid they...

    I need a self-contained module that plugs into our existing vehicle management software and lets me drop an entire folder of images—often 1,000 – 2,500 at a time—and have every photo land on the correct vehicle record automatically. Key behaviour • The module reads the Vehicle ID embedded in each filename and uses that to match the photo to the right record. No manual pairing screens or look-ups. • Supported formats must include JPEG, PNG and GIF. • The system should be comfortable handling batches in the low-thousands without timing out, losing images or duplicating records. Workflow example I export photos from the camera, rename them with the Vehicle ID (e.g. , ) and place them in one folder. When I trigger the upload, the module should detect each...

    **This is not a job portal** **A landing page is Must** The platform should enable companies to register using their official business email address and submit hiring requirements through the portal.

Recruiters should be able to work on assigned requirements, submit candidate profiles, update hiring progress, and maintain a centralized candidate database. Clients should be able to log in at any time to track the progress of their hiring requirements and view the status of submitted candidates. One of the key objectives of this project is to build a reusable Candidate Database. Every candidate added by recruiters should become part of a centralized dat...

    I want to launch a fully-featured online poker platform that players can access directly or that operators can bolt onto an existing casino / sportsbook via a clean, well-documented API. The core games are Texas Hold'em and Omaha, both running on a provably fair RNG with real-time hand history and rake tracking. Players should be able to register, log in and start a table or join an existing one, then deposit through Credit or Debit Card and the most popular cryptocurrencies (BTC, ETH, USDT). A cashier module with KYC hooks, risk limits and automated withdrawals is required so the site can run at the lowest possible operational fee. The user interface must follow a completely custom design. I will provide brand guidelines; everything from lobby to table animations should match that ...
