Muhammad Zain Vazir
AI Engineer | Data Scientist | LLM Specialist

I design and build end-to-end AI solutions that turn complex data into real business results. For creating machine-learning models, and agents, I handle every step, from data preprocessing, to model training, and scalable deployment.

I stand out because of my hands-on experience with LLMs and real-time AI apps, and my multilingual communication skills, and working many different states abroad, which help me collaborate effectively and bridge gaps in global environments, with a strong record in teaching as well.
