Beth Parnell - Software Engineer

Full-stack software engineer building practical, scalable web applications.

I’m Beth, a software engineer with experience across clinical technology, AI-powered workflows, technical education, and e-commerce. I turn complex requirements into thoughtful, maintainable software that helps people and teams work more effectively.

Featured Work

Practical products built around real operational needs, clear workflows, and measurable outcomes.

ClinMatchGO

Reduces manual searching and sorting in clinical trial recruitment. Volunteers get a clear path into relevant studies; research teams get structured matching and outreach tools instead of scattered spreadsheets and one-off communication.
