Hi, my name is Allistair. I'm a second-year Computer Engineering major at Georgia Tech interested in cybersecurity. I do vulnerability testing in my free time, and am currently interested in PostgreSQL security and privilege escalations. I also do security reviews: if you have a dynamic PostgreSQL database with lots of moving parts, I'd be happy to take a look at it. [ recent blog posts ]
