Hi, I'm Hieu Nguyen, someone who is always tinkering and exploring everything... from new technologies to how complex systems operate deep underneath. To me, programming is like dismantling problems and reassembling them into streamlined solutions. Currently, I am enjoying my journey of creative freedom, focusing on building AI-integrated applications and constantly challenging myself with new technical problems.
