At Ranen Investments, I analyze business and operational data to identify trends and actionable insights. I prepare, clean, validate, and organize datasets to improve data quality and reporting accuracy.

I use Python and SQL for analysis, reporting, and data transformation, and develop and maintain analytical reports and dashboards to support management decision-making.

On Mwosho, I worked on an AI-powered data quality automation SaaS for cleaning, validating, standardizing, and analyzing business data. I also list Ranen, an enterprise hospitality management system, and Roach, an AI-assisted trading system, among my selected projects.

My background includes software engineering, data analytics, AI evaluation concepts, and automation. I’m interested in AI evaluation, data quality, AI training, model assessment, annotation, and research.
