🚀 Building a company? I work with promising projects to launch their creator community. See my advisory services.

Community events/hackathons

I build communities for technology events and products. This includes hackathons like the TRON DAO Hackatron and exciting, interactive workshops to explain what is NFT/blockchain.

Usually these events are public, see some past appearances.

Here is a paid promotional video I did for TRON vs. Ethereum.

More music:

Civic projects:

  • SEPTA rail scheduling 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. Patent application.
  • 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.
