Back-end Developer & Test Automation EngineerContributions:2 releases, 4 reviews, 186 commits in 1 year
Contributions summary:Vincent primarily contributed to the development of the Surge Swift library by implementing new functionalities and improving existing ones. They added a `Vector<Scalar>` type along with corresponding unit tests, making `Matrix<Scalar>` conform to `ExpressibleByArrayLiteral` and `Collection` protocols, and implemented matrix-vector multiplication. Their contributions involved fixing indentation and linting warnings, and ultimately enhanced the library's capabilities with new operators and functions, and implemented several unit tests to verify the correctness of the library.
