Summary
🤩
Rockstar🎓
Top SchoolSourabh Tomar is a Senior Software System Designer based in Bengaluru with 9 years of experience specializing in compiler and system software engineering for C/C++ and Fortran. He has driven design, implementation, and maintenance of compiler features at AMD and contributed upstream to LLVM/Flang—most notably improving DWARFv5 and Fortran debug-info generation and developing initial OpenMP lowering into MLIR. His work blends low-level debugging metadata fixes with higher-level lowering design, making debuggers more reliable for optimized Fortran code. A pragmatic reviewer and maintainer, he has a track record of shipping compiler fixes that reduce redundant debug information and correct subtle flag and parameter-name issues. Prior experience in HPC porting and performance tuning gives him a strong systems-performance perspective beyond compiler internals.
