Timeline
2019
IDKollen is a Swedish IT company providing secure digital communication based on BankID authentication. Its services allow companies, banks, and public agencies to authenticate people online or by phone.
The company's products support secure message delivery, authenticated responses to company requests, and GDPR form submission linked to Swedish personal identity numbers.
Business Challenge
The client operated several separate applications for services involving Swedish BankID verification.
The existing PHP applications did not provide the stability and security required for systems handling national identification data.
IDKollen needed a platform capable of supporting increasing data volumes and continued functional expansion.
The client wanted to combine its services into one tab-based product with a React frontend and Java backend.
Our Solution
Approach
Binariks provided a team composed of a PM, a lead backend developer, a frontend developer, and a QA specialist to deliver a highly-scalable, secure, and packed with diverse features platform that unites and expands basic functionalities of the client’s applications. The final product is a GDPR-compliant solution with Java at backend and React at frontend.
Implementation
After the preliminary analysis of the client’s requirements and specific project demands, our software development team started creating an application from scratch. We chose Spring framework to develop a stable and scalable backend of the platform. React was chosen as the main solution for creating the application’s frontend. Our frontend developer successfully implemented the user interface designed by the clients.
After the synchronous development of both backend and frontend for the platform, we launched the quality assurance stage which included the following steps:
- Requirements gathering and analysis
- Test planning and design
- Functional testing and graphical user interface (GUI) testing
- Regression testing and Smoke testing execution
- Final test reporting
Postman was chosen as a reliable solution for API testing. Also, our backend developer conducted numerous unit tests to ensure the quality of the application.
We are still engaged on the project and constantly expand the functionalities of the client’s platform and introduce features that will facilitate.
Technologies Used

All the requirements of the client have been met because the provided platform incorporates all the requested functionalities and even expands them. Also, IDKollen was satisfied with the results of the external code review that showed that Binariks software developers had provided a high-quality product.
The platform is a single, secure, multifunctional, and highly-scalable solution adapted to work with continuously increasing loads of data, which means that the main business challenge faced by IDKollen is solved.
