At CODEFUSION we understand that one of the ways to succeed in our highly competitive industry is innovation. This is one of the reasons why we have always been at the cutting edge of technology and why we have always tried to contribute to change for the better in software engineering. We often work on interesting ideas that can improve our daily work. A good example of this is Jaskier: a set of programs that support continuous defect prediction. This innovative technique involves using machine learning to detect problems in software at the development stage. The programmer receives a prediction of the problem coming from the model and can react in time to prevent the error from manifesting itself in the finished software. We will present the results of our work at the „The 33th International Conference on Industrial, Engineering & Other Applications of Applied Intelligent Systems”. We regret very much that due to the pandemic, the conference will be held between July 26 and 29 online and not in Kuala Lumpur, Malaysia. But nevertheless, we will proudly present our software, the ideas and the results of our research.
