I am a PhD in Computational Fluid Dynamics (Maths + Physics + Coding). My passion is numerical programming but I always try new technologies. I started coding with QBasic at high school then picked Fortran and C/C++ for university projects. High-performance computing is necessary for CFD codes that's why I know OpenMP and MPI. Every now and then I visit Python to use its math libraries. I have developed many numerical apps with WPF(C#+XAML MVVM pattern) and, recently, several projects with Razor pages and Blazor WebAssembly. Therefore, I always have questions and answers about those topics.
