Freelancer Overview

I am a detail-oriented professional with hands-on experience in data annotation for AI model training, including video, audio, image, and text labeling. At Telus International, I supported computer vision and NLP projects by annotating complex multimedia data, transcribing audio, labeling metadata, and ensuring quality through rigorous QA rounds and feedback integration. My background in pharmacy and backend engineering gives me a strong foundation in healthcare data, digital tools like Google Workspace and GitHub, and technical skills in Python and MySQL. I am committed to delivering high-quality, reliable training data and thrive in remote, collaborative environments.

As a Data Annotator at RWS, I labeled multimodal datasets including video, audio, image, and text for fine-tuning and evaluating AI models. I applied consistent, guideline-driven labeling, assigned outcome labels such as success, partial, and failure, and documented errors or inefficiencies. Batch uploads included required timestamps and detailed notes following strict standards. • Maintained accurate annotation logs and submitted on-time data batches. • Conducted spot-checks and corrected peer inconsistencies. • Followed remote work and screen recording policies. • Contributed to large-scale AI project datasets.

At Telus International, I annotated multimedia data including video, audio, image, and text for AI model training and assessment. Tasked with watching videos in full and producing timestamped step-by-step descriptions, I transcribed audio, labeled non-speech sounds, and added relevant metadata. My responsibilities also included media quality selection and updating annotations per reviewer feedback. • Participated in QA rounds to maintain annotation standards. • Flagged and documented low-quality or duplicate media instances. • Applied project guidelines strictly throughout all tasks. • Delivered reliable data for robust model evaluation and training.
