My favorite geometric artwork. It represents the harmony between symmetry, topology, and continuous transformation.

I’m Abdelrhman Sersawy, a software developer and GNU/Linux enthusiast (Arch user 🙂) interested in database systems and backend engineering, especially how large-scale software works behind the scenes. I love open source and actively contribute to it (e.g., Checkstyle, LLVM, Postgres eco-system tools (pgmoneta, pgexporter, pgagroal) ). (See my contributions).

Beyond that, I’m passionate about competitive programming - ICPC World Finalist 2026, (ECPC) National Gold Medalist, (ACPC) Regional Bronze Medalist, and a Master on Codeforces.
