Worked on the SpinalHDL/SpinalHDL repository to enhance the configurability and scalability of arithmetic paths within the codebase. Delivered a feature that replaced the previously hardcoded Mantissa width of 32 in extendedMantissa with a dynamic, parameterized value, allowing the module to support varying input sizes and adapt to future requirements. This change involved architectural refactoring to remove magic numbers, improving both maintainability and readability of the numeric core. The work demonstrated skills in Scala, backend development, and functional programming, with a focus on careful change management and forward compatibility, though no major bugs were reported or fixed during this period.
