Labeling Experience

AI Specialist & Trainer

Image
During my time as an AI Specialist & Trainer at Silencio, I performed advanced annotation of video and image datasets. I evaluated the accuracy and consistency of annotation outputs. I also introduced systematic feedback mechanisms and refined annotation instructions to ensure training data quality. • Annotated videos and images with detailed schema guidance. • Validated and adjusted AI outputs according to requirements. • Instituted regular feedback sessions for process improvement. • Led workshops to train and mentor new annotators.

AI Trainer

Text
As an AI Trainer at Magic Newton Foundation, I contributed to the early phases of training and deploying an AI agent to perform decentralized finance tasks. My involvement focused on curating and assessing data responses for supervised learning. I ensured the agent performed both simple and complex actions by evaluating outputs and refining feedback loops. • Evaluated AI outputs and identified inaccurate or unintended behavior. • Designed and administered task prompts and assessments for LLMs. • Implemented quality control for supervised training cycles. • Supported continual improvement through careful task review.

Transcription Project Lead

AudioTranscription
I led and executed audio and video transcription projects, primarily focusing on underrepresented dialects and recordings with noise or low quality. Through structured review cycles, I delivered highly accurate and comprehensive text corpora. My workflow included text normalization and annotating disfluencies to enhance model training datasets. • Managed transcription workflow from raw data to reviewed text. • Accounted for linguistic variation and background noise. • Completed multi-stage quality assurance protocols. • Ensured model-readiness and text corpus accuracy.

Quality Assurance & Task Evaluator

Text
For two years, I undertook QA and evaluation of data labeling projects by auditing, grading, and documenting datasets. My duties focused on defining instructions, grading criteria, and documenting tricky labeling edge cases to improve accuracy. The process resulted in more reliable, model-ready datasets for downstream training tasks. • Implemented dataset grading with rubrics for error detection. • Authored clear documentation and troubleshooting guidelines. • Enabled more effective labeling through refined team workflows. • Reduced project ambiguity by clarifying edge-case criteria.

Audio Data Annotator

AudioTranscription
As a data annotator specializing in audio, I prepared data for robust speech recognition modeling. My tasks included segmenting long recordings, marking speaker changes, and tagging non-speech events. I maintained consistency and accuracy across diverse audio sources using detailed workflows. • Labeled call-center logs, interviews, podcasts, and field recordings. • Used segmentation for efficient turn-taking and event tagging. • Ensured consistent categorization and high-quality corpus standards. • Collaborated on refining annotation schemas for speech projects.
