(a.k.a. Ben Eisner)

I'm a lead software engineer with an interest in offensive security.

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.

For the past year, I've been studying offensive security — focusing on penetration testing, exploit development, offensive tool development, and adversarial methodologies. Right now I'm working toward my OSCP and CPTS certifications.
