Apps built fast with AI tools often ship with open databases, exposed keys and public file storage. I find those gaps, fix them, and re-test to prove each one is closed.
Background: 6+ years in network security and DDoS defense, root-causing live attacks for enterprise platforms. Python, PostgreSQL, Supabase, Burp Suite, Wireshark.
