Worked on the microsoft/STL repository to enhance both performance and precision in core C++ libraries. Delivered an optimization for ARM64 by improving the steady_clock::now conversion from 24 MHz to nanoseconds, using overflow-safe arithmetic to increase accuracy and reliability in time measurement. Later, expanded the <cmath> library to support 80-bit long double types by safely casting inputs to double, broadening floating-point compatibility without altering the public API. These contributions focused on system programming, floating-point arithmetic, and library development, resulting in more robust time utilities and improved support for high-precision calculations across diverse C++ environments and architectures.
