About EmployeeReferrals project

EmployeeReferrals revolutionises recruitment, improves HR processes and helps with referral management. The company is a global leader in recruitment and the most trusted online referral platform, with close to one million users referring candidates to businesses across industries.

Delivered solution

Over six hundred thousand candidates have been offered jobs through EmployeeReferrals. To help achieve this milestone, iRonin’s dedicated team needed to manage numerous integrations simultaneously, deliver a seamless experience, structure a scalable core platform, and maintain the entire platform.

Goals and results

Handling multiple integrations simultaneously

We built a system that handles multiple third party software integrations and optimised synchronisation of requests to boost performance.

Building the core of the business

To allow for new integrations with popular recruitment software products, the platform had to scale well, make fixes easy to introduce, and allow for efficient implementation.

Enhancing and maintaining a complex platform

We added custom functionalities and worked on improving the platform’s architecture to maintain its competitive edge as new technologies emerge.

Improved test coverage

Testing the platform and its new features as they are introduced is crucial for ensuring overall software reliability. Thanks to good Quality Assurance practices, we avoided issues during deployment.

Synchronised processes

All requests for integrated third party software are handled seamlessly thanks to an appropriate integration setup. They can be managed simultaneously thanks to well-designed system architecture.

Introduced best code practices

iRonin.IT’s team introduced top industry coding practices to improve code quality, reliability, efficiency and security, and make the codebase easy to understand. Each team member follows these guidelines with every code delivery.

We’ve seen our turn rate go down significantly, decreasing at least by half since we’ve had iRonin stabilise our system in all the odds and ends that we need. With a lot of other contractors and agencies that we have worked with, few do test-driven development or release code with tests. iRonin.IT consistently releases tests to ensure everything is of good quality.
