Diana Gizzatkulova contributed to the aggink/Study repository by developing three core features over two months, focusing on robust backend solutions. She introduced the FracNumber class in C# to enable precise rational number operations, leveraging object-oriented programming and operator overloading, and ensured reliability through comprehensive unit testing. Diana also built an external API data fetching service using asynchronous programming and integrated it with the existing service factory, expanding the system’s data capabilities. Additionally, she designed and implemented a sweets management system with new database models and CRUD endpoints, applying Entity Framework Core and sound database design principles throughout her work.

May 2025 performance summary for aggink/Study: Delivered Rational Numbers support by introducing the FracNumber class in C#. The class represents rational numbers with overloaded arithmetic operators and comparisons and is supported by a suite of comprehensive unit tests. FracNumber was integrated into the main program's service runner, enabling precise numeric operations throughout the workflow. Primary commit (dcc173b135f52f2c0a19840b0abae5f16981ff5e) records the feature activation. Business impact includes improved numerical accuracy, reduced rounding errors, and enhanced reliability of numeric workflows, positioning the project for broader numeric type extensions. Technologies demonstrated: C#, object-oriented design, operator overloading, unit testing, test-driven development practices, and service runner integration.
