EXPERIENCE HIGHLIGHTS
Department of IT - National Aviation University - Kyiv, Ukraine
October 2024 - Present
Backend Software Engineer and System Analyst
• Analyzed the educational systems "Teacher Rating" and "Learning Management" to identify underdeveloped functionality, security issues, system performance problems, data structure, and integrity. For the analysis, I used the following methods: studying documentation and requirements, conducting interviews with end-users who had already used the system, analyzing registration, authentication, and authorization by entering different data into the system, and examining the database structure by checking relationships between tables, indexing, and data encryption. During the system analysis, the following issues were identified:
◦ The "Teacher Rating" system has over 50% of its functionality underdeveloped; it had invalid data, which led to performance problems; functional issues related to generating a complete list of teachers by faculties and departments; authentication and authorization problems.
◦ The "Learning Management" system has issues with authentication and authorization.
• Developed a proposal to address the most urgent issues in the systems, which includes the following steps:
◦ Rewriting the "Teacher Rating" system using a microservices architecture, including a revision of the role and access control system, as well as implementing a data validation system to improve security and reliability.
◦ Integrating the "Teacher Rating" and "Learning Management" systems using a unified database to prevent data duplication and improve operational efficiency.
◦ Implementing data hashing to enhance security and protect confidential information.
The proposed changes were successfully approved and accepted by the Head of the IT Department for further implementation.
• I proposed and developed alternatives to paid libraries by creating solutions in Python using the Selenium and BeautifulSoup4 libraries for integrating and processing data from the Scopus database into university systems.
• Implemented a search system for faculty research articles in the Scopus database using Python and Selenium, and refactored the monolithic "Teacher Rating System" into a microservices architecture in Java with Spring Framework to enhance scalability and flexibility.
