About Me

Building AI Systems
From First Principles

I'm a Computer Science graduate from FAST National University of Computer and Emerging Sciences (FAST NUCES), Islamabad, with a deep passion for Artificial Intelligence, Large Language Models, and Generative AI.

What sets me apart is that I don't just use AI frameworks — I build from scratch. I've implemented GPT and Transformer architectures from the ground up in PyTorch, fine-tuned LLMs on domain-specific corpora, and shipped production-grade AI systems end-to-end.

My work spans LLMs, NLP, Computer Vision, RAG systems, Knowledge Graphs, and Intelligent Automation. I'm currently executing a structured AI/LLM engineering roadmap, actively working with LangChain, LangGraph, agentic workflows, and voice AI.

Research Paper

Evaluating the Performance, Quality, and Noise-Resilience of Quantum Random Number Generators via Qiskit Aer Simulators

A research study evaluating quantum random number generators (QRNGs) using IBM's Qiskit Aer simulation framework. The research focuses on assessing the statistical quality, performance benchmarks, and noise-resilience properties of QRNGs across various quantum circuit configurations, leveraging Shannon Entropy metrics and noise mitigation techniques.
