What I'm looking for
I am an AI Data Specialist with hands-on experience in annotating and labeling text, image, and audio datasets to support machine learning projects. I focus on delivering high-quality, consistent data to improve model performance.
From 2020 to 2022 I worked as a freelance Data Annotator and Data Entry Specialist, using multiple annotation tools and performing rigorous quality assurance on large-scale datasets under tight deadlines. I collaborated with data scientists to refine annotation processes and boost model accuracy.
Between 2022 and March 2025 I served as a Toll Collector and Monitoring Officer at the Nairobi Expressway, where I developed strong organizational, reporting, and operational-tracking skills in high-pressure environments. This role strengthened my data reporting and attention-to-detail capabilities.
I am dedicated to accuracy, process improvement, and teamwork, and I am passionate about contributing high-quality data to drive AI and machine-learning innovations.
