CoachLeads

Gym management SaaS product

A software-as-a-service product for gyms that brings member management, attendance tracking, and administrative workflows into one system, with web and mobile interfaces.

The problem: Gyms often track members, attendance, and admin work across separate tools and spreadsheets.
My work: Reviewing authentication, tenant isolation, input validation, and failure handling before launch. Testing forms, responsive layouts, and kiosk privacy.
