I’m an AI Data Annotation & Model Training Specialist in Nairobi with 2+ years of experience creating high-quality labelled datasets for ML and LLM workflows. I’ve worked across video, image, audio, and text annotation, including object tracking, transcription and linguistic QA, RLHF-style pairwise/instruction-following evaluations, and multilingual (English/Swahili) quality scoring. I bring a strong data-integrity mindset from earlier IT support roles in high-compliance environments, which helps me consistently hit guideline compliance, accurate error logging, and reliable delivery even when projects switch between different annotation standards. I’m comfortable working remotely and asynchronously across distributed teams, quickly adapting to new tools, review protocols, and production SLAs to keep annotation and QA accuracy at very high levels.…I’m an AI Data Annotation & Model Training Specialist in Nairobi with 2+ years of experience creating high-quality labelled datasets for ML and LLM workflows.
