Labeling Experience

Senior AI Operations Lead & Linguist

AudioTranscription

I led high-fidelity transcription and multimodal data curation to support training of speech and computer vision models. Using acoustic mapping and audio-visual evaluation, I supervised audio labeling processes to bolster model discrimination capabilities. My work delivered robust data for advancing speech processing in frontier AI tasks. • Curated and transcribed diverse Swahili and English audio datasets. • Employed Praat and Subtitle Edit for precise acoustic transcription workflows. • Established quality assurance benchmarks for multimodal labeling outputs. • Provided linguistic feedback to enhance speech data annotation accuracy.

LabelboxVideoRLHFAction Recognition

I executed over 5,000 complex data annotation and preference ranking tasks to enhance model naturalness and reasoning capabilities. My work focused on aligning large language models through Reinforcement Learning from Human Feedback (RLHF) and Supervised Fine-Tuning (SFT). Using high-precision annotation schemas, I ensured zero-error workflows for next-gen AI systems. • Conducted multi-tier text annotation, ranking, and evaluation of both English and Swahili outputs. • Architected and implemented annotation guidelines for high-accuracy preference ranking. • Oversaw the transition from manual data entry to AI-first scalable annotation pipelines. • Led linguistic QA to detect failures and reduce model hallucinations.
