What I'm looking for
I am a detail-oriented data annotator and AI trainer with extensive experience building and curating high-quality datasets across text, image, audio and video for NLP, computer vision and speech recognition projects. I design and implement annotation guidelines, perform QA, and collaborate with cross-functional teams to ensure accuracy, consistency and scalability in data used to train and evaluate machine learning models.
I have worked on annotation, transcription, dataset development and model evaluation with multiple global platforms and enterprise clients, refining active-learning cycles and contributing to improved model performance through careful labeling, metadata enrichment and bias mitigation practices. I bring strong problem-solving, critical-thinking and communication skills, and I am committed to delivering precise, reliable datasets that drive AI innovation.
