About

A quality mindset built through research and review

Research taught me not to force a clean story when the evidence is messy. In my projects, I keep sample counts visible, compare expected and actual outputs, trace inconsistencies back to their source, flag limitations, and write recommendations that another person can act on.

Selected work

Completed projects that show how I investigate quality

These case studies are based on completed internship, research, and course work. The public versions use cleaned summaries and do not claim direct assistive-technology testing or other experience that has not been completed.

Completion rates across seven audited public business profiles.
