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.

    I need a seasoned developer to build a payment gateway entirely from scratch something like . The core engine must process real-time sales, captures, refunds, and voids while meeting strict PCI-DSS requirements and passing 3-D Secure 2.0 checks. Connections to be established: Cybersource, Mastercard Payment Gateway Services, and several domestic bank APIs (full specs will be shared after NDA). All routing, tokenisation, and risk responses should be abstracted behind a clean REST/JSON interface so the storefront can call a single, unified endpoint regardless of the underlying acquirer. Multi-currency support is essential; settlements will initially run in USD, EUR, and AED, with room to add more. Please architect currency tables, FX mark-ups, and reconciliation reports accordingly. ...

    Antigravity is already installed and my Ollama daemon is serving four-five local LLMs flawlessly. Antigravity’s agents talk to those models entirely offline. We will hop on AnyDesk or Zoom—my preferred interface for this job—and you’ll: • Point Antigravity to the localhost endpoints exposed by Ollama • Verify bidirectional communication with at least one sample prompt/response per model • Leave me with the edited config files or environment variables and a quick note of the steps taken No other integrations are required—just Antigravity ↔ Ollama. Once we can pull responses from the local models without touching the cloud, the task is complete.
