What I'm looking for

I’m available for remote contract work involving Swahili language evaluation, AI training, AI model testing, linguistic data annotation, language quality assurance, transcription, and related language-technology projects.

As a Freelance Swahili Language Specialist & AI Data Evaluator, I evaluate AI-generated responses in Swahili and English for accuracy, fluency, relevance, and natural language usage. I explain linguistic and contextual errors and assess responses against project rubrics.

Across annotation and evaluation projects, I’ve reviewed thousands of AI data items and maintained approximately 95%+ accuracy/quality. I also compare model responses, identify recurring failure modes, and provide structured feedback for improvement.

Since 2019, I’ve written, edited, and proofread digital content, completing 500+ articles and content pieces. I also work on Swahili and English transcription and language review, checking transcripts against audio and maintaining 95%+ quality standards.
