What I'm looking for

I'm looking for remote or hybrid data annotation, transcription, data quality, or dataset analysis work where I can apply precision-driven SOP workflows to ML, autonomous-driving, ADAS, and NLP datasets.

I've delivered high-precision annotation and data-quality work for Align Turn, iMerit, CloudFactory, and Remotasks across audio, video, image, LiDAR, and language datasets.

I transcribe English and Swahili audio in full verbatim, align speaker segments with waveforms, and evaluate AI-generated text for accuracy, fluency, consistency, and contextual relevance. My annotation work includes 2D/3D point clouds, semantic segmentation, bounding boxes, cuboids, object tagging, and taxonomy classification.

I work carefully within strict SOPs, identify recurring labeling and ontology issues, and support reliable ML, autonomous-driving, ADAS, and NLP datasets through QA reviews and structured feedback.
