Labeling Experience

Lead Data Annotator

LabelboxTextRLHF

As Lead Data Annotator, I managed end-to-end data labeling pipelines for LLMs, focusing on English and Swahili text. I ensured consistently high annotation accuracy across complex reasoning datasets. I led the Swahili linguistic team, established regional guidelines, and performed quality audits on multi-modal datasets. • Led daily quality audits and bottleneck resolutions. • Developed processes for managing image-text and video sequencing data. • Collaborated directly with machine learning engineers for workflow improvement. • Managed a team specializing in regional dialects and cultural nuance.

As Senior Content Evaluator, I supervised a specialized team focused on semantic metadata tagging for extensive media libraries. I created Gold Sets for staff training and led consensus exercises for ambiguous natural language processing tasks. I specialized in accessibility labeling, including SDH and descriptive audio metadata. • Supervised 15 labelers for semantic standards. • Developed standards for new team training. • Led blind-testing for ambiguity resolution. • Specialized in accessibility and descriptive labeling.

Visual Semantic Mapping Project Lead

LabelboxImageObject Detection

I led the manual labeling of over 10,000 complex urban scenes to support computer vision model training. I emphasized precise object detection and environmental context tagging for greater model accuracy. I managed annotation quality for challenging urban scenarios. • Oversaw image-based object annotation. • Ensured precision for computer vision models. • Focused on environmental context tagging. • Coordinated team efforts for quality control.
