Comprehensive Fintech App QA and Security Audit
Budget: $30 – $250 NZD
Full Fintech Web App Testing, Security Audit & Mobile Readiness (React + Supabase)
Project Overview
We are looking for an experienced full-stack / QA-focused developer to take ownership of testing, fixing and launch readiness of a fintech web application.
