About Me
Hello world! This is Hafiz Abdullah Amjad, a Full-Stack Software Engineer with 1+ year of professional experience delivering production web applications, custom Shopify apps, and enterprise CRMs end to end.
With a strong academic foundation (BS in Computer Science from University of Management and Technology, Lahore with 3.84 CGPA) and industry experience at Integriti, I specialize in architecting end-to-end solutions — from multi-tenant CRMs with real-time WebSockets and bulk GraphQL sync engines to intelligent multi-agent LangGraph tutoring systems.
I thrive on engineering resilient backend architectures, solving complex business workflows, and deploying scalable modern web applications across Linux, Docker, and cloud platforms.

Lumina (Agentic AI Tutor)
Pakistani freshmen face English-medium lectures and rigid teaching methods. Existing AI chatbots fail to offer culturally-aware, pace-adaptive support, leading to low confidence.
✓Built a multi-agent AI architecture managed by a central coordinator using Next.js, Express.js, and FastAPI.
✓Trained a Random Forest model on student onboarding data to identify at-risk students automatically.
