Additionally, I designed, developed, and implemented an MS Office extension for processing documents and streamlining operations in the Foreign Trade and Purchasing department. This extension significantly reduced document processing time by up to 5-6 times, effectively addressing issues related to typos, misprints, and other errors in documents for customs clearance. As a result, it contributed to a 24% reduction in customs service expenditures. The extension was released in 2019 and continues to be in use to this day.

Accomplished four study projects that provided me with foundational developer skills:
- Developed proficiency in using Git for version control, enabling efficient collaboration and code management.
- Gained confidence in JavaScript programming, mastering fundamental concepts and applying them to build interactive web applications.
- Acquired the ability to create well-structured and visually appealing webpages using HTML, ensuring proper markup and semantic structure.
- Developed the skills to set up and deploy projects from scratch, gaining knowledge of configuring development environments, initializing repositories, and deploying applications to production environments.
These study projects allowed me to apply theoretical knowledge in a practical setting, reinforcing my understanding of essential developer skills. Through hands-on experience and iterative learning, I became adept at using Git, writing JavaScript code, creating web layouts with HTML, and setting up projects from start to finish. I am eager to further enhance these skills and take on more challenging projects in the future.
