Hi, I'm Abdelrahman πŸ‘‹

CS @ University of Southern Mississippi Β· ICPC South USA Regional Champion πŸ†

I like hard algorithmic problems and shipping fixes to the open-source tools people actually use. Strongest in C++, Python, and Rust.


🌍 Open Source

Real fixes and tests in tools I actually use:

# Project What I did PR Status
1 NVIDIA/cccl ⭐2.5k Fixed Thrust's CPU stable_sort reordering -0.0 and +0.0 (#750) #11897 πŸ”„ In review
2 NVIDIA/cccl ⭐2.5k GPU stable_sort test for NVIDIA's nvc++ compiler #11882 βœ… Merged
3 NVIDIA/cccl ⭐2.5k GPU sort test for NVIDIA's nvc++ compiler #11881 βœ… Merged
4 emscripten ⭐27k Added the desynchronized WebGL context attribute #27163 βœ… Merged
5 vyper ⭐5k Codegen fix: raise instead of silently returning in safe_pow() #5134 βœ… Merged
6 rust-lang/rust-analyzer ⭐16k Guarded an index panic in flycheck handling #22634 βœ… Merged

πŸš€ Projects

  • competitive-programming: my solved-problem archive across online judges (Codeforces, DMOJ, and more to come), every solution the real submission with its solve date.
  • Found.it: Hatchathon finalist, built with two teammates. Semantic file search that indexes and searches on your own machine (FastAPI, Electron, sentence-transformers, FAISS), with chat through OpenRouter or a local Ollama model. I wrote its GPU search as a CUDA C++ kernel: 9x faster than FAISS on the CPU at 1M vectors, at 91% of the GPU's peak memory bandwidth.
  • pdf-darkmode: converts any PDF into a true dark-mode file locally (Python). Inverts lightness while preserving hue, so colored text stays readable and photos aren't turned into negatives.
