I’m a PhD-qualified language and interdisciplinary specialist from the University of Nairobi, focused on linguistic analysis, multilingual communication, and content evaluation. I help teams assess, compare, and refine written data with accuracy and consistency.

In my Graduate Teaching Assistant role (2019–2023), I evaluated and graded large volumes of written work while maintaining high standards for grammar, coherence, clarity, and overall text quality. I used structured evaluation frameworks similar to data annotation guidelines and delivered detailed, actionable feedback to improve content effectiveness.

I also bring strong capabilities in assessing differences across responses through comparative analysis and pairwise comparison, with a clear emphasis on attention to detail and data quality assurance. I’m comfortable labeling, validating, and applying guideline-driven processes to support AI training workflows.

I work effectively in remote, work-from-home environments, managing tasks with dependability and a flexible schedule (20+ hours per week). I’m ready to contribute to teams that value structured guidelines, consistent quality, and measurable improvements in language and text outcomes.
