React Native App Security Audit & Store Release — Fix Issues and Publish to App Store + Google Play
Straight to the point, knew what he was doing, delivered exactly what was promised. App is live on both stores, security issues are fixed, and the whole thing was done faster than expected. Highly recommend.
