Back-end Developer
Back-end DeveloperContributions:100 commits, 60 PRs, 15 pushes in 2 years 4 months
Contributions summary:Sumith primarily focused on improving the printing functionality of the SymEngine library. They addressed missing parentheses issues in the output of mathematical expressions, making the printed output more accurate. Their work included modifying the code in `src/pow.cpp` and `src/mul.cpp` to change how power expressions are printed to match SymPy's style. Additionally, the user added and updated tests to ensure the correctness of the printing output, especially related to the handling of parentheses.

Role in this project:QA Engineer / Test Automation Engineer
QA Engineer / Test Automation EngineerContributions:7 commits, 9 PRs, 70 comments in 1 year 2 months
Contributions summary:Sumith primarily focused on implementing and updating tests for matrix-related functionalities within the sympy library. Their contributions involved writing tests for the `columnspace` method and ensuring the correct behavior according to mathematical definitions like the rank-nullity theorem. They also added test cases related to operator functionalities and included fixes to documentation. The user also updated docstrings to provide a clear understanding of methods and their usage.
