Olorunfemi Festus

I am a detail-oriented business analyst with five years of experience in evaluation, annotation, quality assurance, and process improvement. I focus on ensuring data integrity and output accuracy through structured analysis and clear documentation.

In my recent role I conducted side-by-side evaluations of AI-generated outputs, performed detailed fact-checking, and produced evaluation reports and justifications shared with stakeholders. I use browser-based tools, extensions, and basic command-line operations to streamline digital workflows.

I have led data annotation and QA efforts, reviewed large datasets for machine learning training, and identified model output error patterns to drive process improvements. I also supported onboarding by training new team members on QA procedures and best practices.

I bring strong reporting skills using Excel, Google Sheets and Notion, a proven track record of improving team performance, and certifications in business analysis and quality assurance that reinforce my commitment to high standards and continuous improvement.
