Rachel Wachira

I’m a detail-oriented Swahili language specialist, researcher, and AI data contributor focused on linguistic analysis, transcription, annotation, and content evaluation. I analyze language structure, grammar, and meaning with high accuracy, then translate findings into quality improvements for AI systems.

In my AI training work with Sigma.AI, I perform annotation, categorization, and evaluation of linguistic data, correcting Swahili and English for grammatical accuracy and contextual relevance. I also contribute to conversational AI testing by identifying language inconsistencies and model errors, while ensuring rigorous quality standards and clear reporting of issues.
