Scouting report

Cuban Android developer building no-root firewall and network-monitoring tools in Kotlin

assessed from open-source footprint

Mid
54signal

Mid-level developer with a small, focused and fully original portfolio (5 repos, zero forks, nothing abandoned) centered on Android security tooling. FireNetStats is a real-time network and firewall monitor, and maxfirewall is a lightweight no-root Android firewall — both in Kotlin. Stars are low (3 total) and there's no separate authorship record, but the niche focus and clean, non-fork repo set make this a tidy, purpose-built mobile/security profile.
