Systems & Software Engineer • Amman, Jordan
Computer Science Student @ The Hashemite University & 42 Amman Cadet

Systems software engineer focused on low-level C and C++, POSIX systems programming, concurrency, and algorithmic optimization.

• push_swap — Dual-stack radix sort on array stacks using coordinate compression to bound passes to $\log_2(N)$; lookahead bit inspection in Stack B cuts redundant transfers, coupled with dedicated heuristic solvers for $N \le 5$.
• philo — Deadlock-free, race-free simulation of Dijkstra's Dining Philosophers using pthreads and mutex locks; built asynchronous monitoring routines with microsecond-precision timers preventing starvation.
• pipex — Unix pipeline engine reproducing shell redirection (< infile cmd1 | cmd2 > outfile) using fork, pipe, dup2, and execve; implements POSIX process synchronization, multi-fd stream redirection, PATH resolution, and child exit status propagation.
• cpps — 42 C++ Modules 00–09 enforcing strict Orthodox Canonical Form, subtype polymorphism, template metaprogramming, and STL algorithms; includes the Ford-Johnson Merge-Insert Sort with Jacobsthal sequence pairing.
• minitalk — Inter-process communication system in C transmitting arbitrary strings bit-by-bit using exclusively UNIX signals (SIGUSR1, SIGUSR2) with PID acknowledgment.

• 42-core — Central curriculum directory tracking low-level C, systems, and algorithms implementations at 42 Amman.
• Programming-Advices-Core — Comprehensive coursework repository containing 225+ algorithmic solutions across 5 levels, 5 normalized relational database schemas (3NF), and foundational C++ exercises.

• 42 Amman — Software Engineering Cadet / Peer Developer | 2025 – Present
  Structured engineering curriculum; conducted 50+ peer technical evaluations and pair-programmed in teams.
• The Hashemite University — BSc in Computer Science | 2022 – 2026 (Expected)
