I consult with SEPTA to help set their rail schedules. Also, I independently measure On-Time Performance of all SEPTA trains. If you are ever late for work because of a late train, use my website as proof so you have an excuse.

Philadelphia Traffic Court

Philadelphia Traffic Court made national headlines throughout 2014 as its offices were raided by the FBI and 9 current and former judges face indictments on 77 counts. I successfully petitioned the Philadelphia government to make public their entire database of traffic violations. Now lawyers use it to appeal old tickets and some people have used the data to find evidence of wrongdoing.

I am active in doing technical research of smart contracts and websites. This includes work with the FBI and Apple.

(Of coures, I never post zero-days against paid advisory clients.)

Recent zero-days:
