Case studies دراسات الحالة
Work that actually shipped. أعمال فعلاً تم إطلاقها.
Every case study here is a production system — no toy projects, no side experiments. Each one explains the business problem, my approach, architectural decisions, and measurable outcomes. كل دراسة حالة هنا هي نظام إنتاج فعلي — مش مشاريع تدريبية أو تجارب جانبية. كل واحدة تشرح المشكلة التجارية، أسلوبي في الحل، القرارات المعمارية، والنتائج اللي ممكن قياسها.
