About Bassem Girgis

Software development for me is a source of joy. I take pride and ownership of my work and that motivates me every day. If I must sum it up, it is the challenge of the innovation that drives me and the sweet reward of creating something new and useful that keeps me happy.I also take joy in working with a highly collaborative and efficient team. I spend the better part of my day with my teammates and having a trust and respect-based relationship with them is indispensable. I actively help my team and I do not shy away from seeking my team’s help as well- Expert in modern C++ 11/14, Python 2/3, SWIG, Fortran 90/03 and MATLAB- Expert in Message Passing Interface (MPI), OpenCL, and multi-threading using OpenMP, C++ threads and Threading Building Blocks (TBB)- Experienced HPC architect of heavyweight back-end development using many technologies including non-relational databases, MongoDB and Redis, Google\'s protobuf and gRPC- CFD expert in FDM, FVM, and FEM simulation techniques using structured and unstructured grids- Developed higher order CFD solvers from scratch- Expert in massively parallel Algebraic Multi-grid (AMG) Methods and Iterative Krylov solvers- Implemented CFD solvers for incompressible/compressible, inviscid/viscous flow fields as well as multidisciplinary physics solvers for combustion and plasma MHD turbulence- Wrote proposals and procured research grants from NASA SBIR Phase I & II programs totaling Developed a generalized parallel processing framework for unstructured arbitrary higher order FEMs using Element-By-Element GMRES and MPI from scratch- Implemented a novel characteristic boundary conditions treatment for implicit arbitrary higher order unstructured FEMs- Developed/maintained CFD solvers supporting LES, RANS, and hybrid RANS/LES turbulence models- Developed sparse linear systems\' solvers using different data structures for large system matrices resulting from FEMs- Developed a quasi 1D gas dynamics solver combined with empirical regression rate model and equilibrium thermo-chemistry module to simulate the hybrid rockets performance- Designed and manufactured a lab-scale hybrid rocket thrust chamber- Experienced in GAMBIT, GridGen, AUTOCAD, TecPlot, ParaView, and FieldView software packages- Experienced in OpenFOAM framework, FLUENT flow solver, and NASTRAN finite element structural solver- Experienced in Linux and Microsoft Windows operating systems
