About

Mechanical engineering graduate with a deep specialization in AI & ML engineering. I freelance across the full stack — from training models and building pipelines to shipping production-ready applications. I believe the future belongs to engineers who understand both the physical and the intelligent world. AIHunt is my contribution to the AI community I've learned so much from.
