FCC (Fortified Central Command) is a cybersecurity mobile application covering Managed XDR, SIEM, Incident Response, Penetration Testing, and Attack Surface Management (ASM). I led the mobile development for this React Native app, taking it from an aging codebase through a major overhaul. That included upgrading React Native from version 0.64 all the way to 0.84, resolving compatibility issues along the way, and optimizing the Android bundle size so the app installed and updated faster.
