Labeling Experience

Video Contributor – Home Activities Video Project | Micro1

Micro1VideoData Collection

As a Video Contributor for Micro1's Home Activities Video Project, I captured structured video data of domestic activities for robotics and computer vision AI research. I adhered closely to technical standards and recording protocols, ensuring footage quality and relevance for model training. Consistent and precise submissions enabled robust downstream annotation and AI model ingestion. • Recorded diverse home activities to support embodied AI research. • Followed strict scene composition guidelines and activity sequencing requirements. • Supported context-aware model interpretation and replication. • Ensured all data matched annotation and ingestion process standards.

Data Annotator | Mindrift

MindriftTextRLHF

As a Data Annotator at Mindrift, I labeled and curated diverse datasets, including text and conversational data for LLM development. My work included preference ranking, quality evaluation of AI-generated outputs, and structured human feedback to enhance model performance. I also interpreted complex annotation guidelines, ensuring high inter-annotator agreement and data reliability. • Labeled training datasets across various modalities for machine learning systems. • Provided RLHF and evaluation ratings to improve model coherence and safety. • Maintained high annotation accuracy within a remote, deadline-driven setting. • Escalated edge cases and annotation errors to uphold dataset quality.
