Hatem M. is a programmer and technical author whose work focuses on modern C++, large language models, and AI systems.

His books combine first-principles explanations with complete implementations and reproducible experiments. They include C++ Algorithmic Mastery, an eight-volume series on algorithms and problem solving; Build an LLM Inference Engine in C++, which constructs a GPT-style inference engine from scratch; LLM Quantization: From the Bits Up, which develops the theory and practice of neural network quantization from the bit level upward; and C++ Autopsy, a forensic investigation of ten subtle C++ bugs that compiled successfully, ran correctly, and still produced the wrong answers.
