Customer

Headquartered in Copenhagen, CrediWire is a software provider for the finance industry. Their flagship product is a platform that enables businesses to automate reporting to banks, auditors, boards, etc. Founded in 2015, the organization is supported by Copenhagen Startup Fintech Lab.

Proccess

As most of the issues, such as performance challenges, troublesome maintenance, and increasing technical debt, resulted from the build process using outdated technologies, HQSoftware’s engineers focused on improving it.

First, our developers utilized Webpack to automate mundane tasks of the build process, as well as support the format of the Vue.js framework. By implementing Babel, experts at HQSoftware ensured that JavaScript’s new syntax is supported by all the browsers. All these measures taken contributed to smooth migration without increasing the technical debt.

To abide by the best practices of software development, our team delivered a library of reusable components, thus optimizing existing code base.

As part of extending the platform’s functionality, engineers at HQSoftware also developed a reporting system that allows for creating a presentation based on the available data (charts, graphs, etc.) and sharing it.

Finally, our developers implemented unit testing.

Challenges

In the course of the project, the team at HQSoftware had to address the following issues:

• Migration had to be performed without downtime or a growing technical debt, as the system was in production with dozens of companies using it daily.
• The legacy build process did not support the format of the Vue.js framework.
• Bower, a package manager employed during the platform’s development, had been deprecated for 3 years already.
• Originating from the lack of components-based development principles, code files contained a lot of duplicates and copy paste. As a result, a single code file could be 5,000 lines long, impossible to maintain.
