Kiplangat Koech
@kiplangatkoech1
Data annotation specialist focused on high-quality datasets and ML model safety.
What I'm looking for
I am a detail-oriented data enthusiast with hands-on experience annotating and evaluating datasets for machine learning applications. Over multiple roles I have delivered high-accuracy labels, performed data pre-processing, and implemented quality checks that improved model performance.
At Google I annotated and labeled datasets, provided feedback to enhance model outcomes, and helped create annotation and quality-control guidelines. At Toloka I collected and pre-processed data from diverse sources, ran consistency checks, and supported protocol improvements to increase efficiency.
I hold a Bachelor in Mechanical Engineering from the University of California with coursework in Machine Learning, Data Structures, and Statistics. I seek flexible remote roles where I can contribute to safe, reliable AI through rigorous data work and continuous process improvement.
