Worked on the dream-num/univer repository to enhance financial modeling capabilities by implementing robust validation for the RATE function. Focused on aligning the formula engine’s behavior with Excel, the work introduced support for zero-payment scenarios and ensured that cash flow sign validation prevents incorrect results when all values are positive or negative. Leveraged TypeScript to develop automated unit tests covering these edge cases, thereby improving code quality and test coverage. This approach reduced the risk of misinterpretation in Excel-like workflows and strengthened compatibility with existing user patterns, demonstrating skills in financial modeling, formula engine development, and comprehensive test-driven development practices.
