Ben Eisner (a.k.a Backuardo)

I'm a lead software engineer and emerging red teamer.

I began programming while serving as an infantry squad leader (0331) in the US Marine Corps. After my service, I studied computer science at Dartmouth College and started getting involved in startups. I was an early engineer at Cameo from 2017 to 2023, where I helped scale the platform to millions of users and later led its crypto initiatives. Currently, I'm the lead engineer at Cedar, a seed-stage startup developing the operating system for urban development.

Right now, I'm deeply focused on offensive security — I spend my free time finding vulnerabilities and developing exploits. I also consult and advise organizations on TTPs for threat defense.
