I'm Johnny Endrihs, hmbldv, the humble dev.

USMC Veteran with 18+ years securing networks. Currently a Director-level security leader in crypto asset management, building security programs from the ground up.

I design and harden identity, network, and cloud systems—mostly in finance where mistakes get expensive fast. This site documents real labs, real configs, and the trade-offs behind them.

Currently pursuing my MS in Cloud Computing at UMGC while exploring AI agent architectures and how to secure them.
