Case study

How we optimized the performance of our client's application by implementing a comprehensive code audit

The costs and maintenance of our client's application were out of control. An application audit performed by Devire IT Services, identified bugs in the code and identified priorities for application development.

Client

The client is a Polish start-up specializing in mobile technologies. Their mission is to develop tools that support sustainable development.

Business need

The application that the company had been working on for years, encountered serious technical problems. The client’s IT team was unable to identify and fix the errors, leading to project delays and mounting costs. The client needed a quick and accurate diagnosis of the problem in order to move forward with the project, meet deadlines and develop the application.

Comprehensive evaluation of existing systems: application audit

We offered the client a comprehensive technical audit of the application.

For the project, we assembled a four-person team of experts with diverse competencies, including risk analysis; data, application, network and infrastructure security; software engineering; and cloud platforms expertise.

The audit team began analyzing the code and technical documentation while assessing functional maturity, software quality, development process and application compliance.

The audit covered three areas: Data Analytics, DevOps & Programming, and UX & Business Analysis and consisted of:

  • Analysis of the cloud solution provided by an external cloud provider
  • Scalability
  • Database
  • Implementation process
  • API performance test
  • Migrating the solution to Azure

  • Results

    Our code review report provided the client with valuable insights into the quality and security of their project. We delivered a comprehensive analysis that empowered our client to make well-informed decisions regarding its further development. Beyond diagnosing issues, the final report included specific recommendations for improvements, along with an analysis of potential risks and associated costs.

    An overview of the code audit completed by Devire

  • Fast turnaround time: 5 working days
  • Detailed and precise diagnosis of problems
  • Comprehensive recovery plan, including priorities and estimated time for implementation
  • Full technical documentation
  • Use of clear and concise language, accompanied by clear graphic design

  • Working with Devire IT Services: Optimizing application performance

    The client identified the source of the problems that contributed to the project's failure, and the reasons for these difficulties were transparently communicated to the entire team. Our team conducted a code audit, providing the client with a realistic view of the current state of the application. This audit became a solid foundation for future development work.

    Code audits are an excellent method for gaining a full understanding of a code structure before moving forward with a project or allocating funds. They can range from a preliminary review of the application, known as a passive audit, to a more advanced, in-depth analysis. This comprehensive approach includes a detailed security assessment, identification of code bugs, estimation of the backlog, evaluation of development processes, and analysis of the team structure. An example of such an in-depth analysis is the penetration testing we conducted for this client.

    Results

  • Four Devire experts identified all errors in the application
  • We optimized the application's performance and scalability
  • We provided the customer with full technical documentation
