PROFILE
Yang
Over six months, contributed to the OI-wiki repository by developing advanced mathematical features and improving technical documentation. Built and optimized C++ implementations for formal power series composition, reversion, and Power Projection, leveraging algorithm design and Fast Fourier Transform (FFT) techniques to enhance performance in polynomial arithmetic and signal processing. Enhanced documentation in Markdown to clarify algorithmic complexity, correct mathematical formulas, and improve onboarding for developers. Addressed documentation bugs, such as correcting FFT time complexity, and expanded coverage to include the Chirp Z Transform and its inverse. Demonstrated strong technical writing, algorithm analysis, and version control practices throughout the project.
