What I'm looking for

I am looking for a role that allows me to innovate in AI training and data annotation while collaborating with talented teams to enhance AI model performance.

I am an AI Training and Data Annotation Expert with a Bachelor of Computer Science from HCMC University of Technology and Education. My passion lies in leveraging my extensive experience in AI training and data annotation to contribute to the development of high-quality training datasets for cutting-edge AI models. I am currently seeking opportunities to apply my technical expertise in data labeling, quality assurance, and workflow optimization in the rapidly evolving field of artificial intelligence.

In my recent role as an AI Training Specialist at Labelbox, I led data annotation projects for computer vision and NLP applications, ensuring high-quality labeled datasets. I designed and implemented annotation guidelines and quality control processes that improved labeling accuracy by 25%. My collaborative efforts with AI engineers refined annotation requirements based on model performance feedback, and I developed custom labeling ontologies and workflows to optimize the annotation process for various AI applications.

Previously, as a Data Annotation Lead at Scale AI, I supervised annotation projects for autonomous vehicles, robotics, and computer vision applications. I created comprehensive training materials for annotator onboarding and skill development, performed quality audits, and implemented corrective measures to enhance workflow efficiency. My contributions to scalable annotation solutions through process innovation and my ability to conduct performance evaluations have consistently driven team success.
