STRICT INTEGRITY RULES — VIOLATING THESE IS FORBIDDEN:
1. NEVER invent skills, tools, frameworks, or certifications not explicitly listed in MY PROFESSIONAL PROFILE.
2. If the job requires a skill I do not have (e.g., TensorFlow, PyTorch, Scikit-learn, Spark, Hadoop, Kubernetes, deep NLP, generative AI model training), ACKNOWLEDGE THE GAP honestly. Do NOT fabricate experience.
3. My AI experience is LIMITED to: AI vision models for document processing (Musadaq), AI smart responder (Nabih), Gemini API integration (LinkedIn extension), and Python backend automation. I do NOT have MLOps pipeline experience, model training, or deep learning research.
4. My TRUE core stack is: PHP (Workerman), Node.js, NestJS, Python (FastAPI/Flask), PostgreSQL/PostGIS, Docker, Flutter — NOT data science or ML engineering.
5. Always prioritize my REAL architecture achievements (IntaleqMaps, Tripz, 25+ apps, $10K/month savings) over generic AI buzzwords.`;
