What's hot

Pacific Medical Training

We employ thousands of workers in entry-level medical jobs. We are also the world's first company to release CPR and advanced life support training courses when new science guidelines are published.

V.P., General Manager since 2013

Nineteen Eighty-Five

A modern printing of the classic George Orwell book. Orwell’s protagonist battles with his own incriminating #searchhistory, the prying eye of the Social Justice Warriors watching him through his smart device…

Published 2021

Blockchain standards

I promote intellectual property and stop fraud using blockchain. This standardizes the sale of physical assets on the Ethereum blockchain.

Engagement as an advisor to blockchain projects, training & developer relations for corporate accounts and code review for developers.

This work was sponsored in part by Ethereum Foundation.

I am hustling to answer everybody's questions about NFT. Day in and day out.

ERC-721 lead author since 2018

Civic projects

EMCCC, PA

Eastern Montgomery County Chamber of Commerce, PA, co-chair government affairs committee board. We work with local, state and federal government representatives to connect local businesses with elected officials.

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.

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.

Advisory and vulnerability research

Clients

My clients in the past year include: Arianee, GenoBank.io, Area, EY, Lucid Sight (MLB Champions), a top aircraft manufacturer, a hedge fund.

Code reviews

Some typical design and code review work I have done includes:

Privacy Log

I am active in doing technical research of smart contracts and websites. This includes work with the FBI and Apple. Usually I publish these on Privacy Log, and sometimes these publications are live zero-days if the vendor failed to take corrective action. (Of coures, I never post zero-days against paid advisory clients.)

Recent zero-days:
