The paper proposes an automated method of classification of source code changes, which consists of two steps – clustering and comparison of clusters of classes. The currently existing methods of improving component software development are analyzed. Based on the analysis, it was established that the optimal method of increasing the productivity of the analysis of changes is the clustering of these changes. A method is proposed, according to which the distribution of changes by clusters is carried out automatically. Their comparison to classes is carried out by an expert. It is shown that the automation of the distribution of changes by clusters significantly reduces the time of examination of code changes, which makes it possible to use the obtained results to improve the quality of software during the development of complex software complexes. The results obtained in the course of the work provide an idea of possible data clustering algorithms with further analysis of the obtained set of clusters according to their parameters. Also, on the basis of the conducted research, the results of the comparison of the classifications of changes in the software system with open source code, performed using the proposed automated method and manually, are given. It is shown that the task of controlling changes that are undesirable at the current stage of development is solved significantly more effectively using the proposed method compared to a full examination of changes, as it allows identifying changes of classes prohibited at the current stage of development with less time spent. The application of the method in practice allows to improve the quality of the code due to the increase in the efficiency of the process of its examination. Using the approach proposed in the paper, the examination process under time constraints can be built more efficiently by selecting changes of the most important classes of changes. It has been proven that the method works perfectly if the same type of changes are analyzed, and when the changes combine heterogeneous code modifications, the quality of the automated classification deteriorates. The obtained results make it possible to extend the application of this method to other software complexes and systems, provided that differences in data types and their parameters are taken into account.

The work describes the main steps, the structure, and the result of web resource for job search, which is relevant in the context of a pandemic and employment loss of a large number of citizens. The focus is on the development of a platform with enhanced protection from the point of view of a job seeker, who can analyze data about the employer, and leave a real feedback both at the job search stage and after employment. For this purpose different user profiles and a real opportunity to leave feedback are provided. A platform is developed using PHP with PDO extension for database connection. MySQL relational database is used as a database. All phases of resource development, from architectural and database planning to the development of layouts and interfaces, are described in details. Special attention to the protection of information transmitted by both employers and job seekers is paid. The functionality of the developed system is analyzed. The received resource has been tested and it has been established that it can be used effectively for both employers and job seekers with the appropriate functionality, the ability to post, edit, delete vacancies and comments about the company. This, in turn, makes it possible to avoid fraud and cybercrime by checking the veracity of the information provided by the employer and forming an employer’s rating based on real feedback from persons who work or have worked there.
