I started my professional life as a hacker in the early 1990s - in the age of SCO UNIX and Windows 3.0.
In 1999, I co-founded Asian School of Cyber Laws and moved into the super exciting field of cyber law and cyber crime investigation. I have had the privilege of assisting the Government of India in framing draft rules and regulations under the Information Technology Act.
My work has taken me to 18 countries and I have investigated cyber crimes & data breaches for hundreds of organisations across many sectors - aerospace, banking, defence, law & tax enforcement, IT, manufacturing, media, medical, pharmaceuticals, shipping, trading, transportation.
I led the team that developed Collaborative Online Investigation Network (COIN) and the ASCL Volatile Evidence Retrieval Tool (Vertool) for quick evidence retrieval from Windows computers.
I developed an interest in virtual currencies in 2011 while investigating a case of organized criminals using bitcoin. Since 2015, I have been working extensively in the blockchain / distributed ledger technology domain.
In 2016, I co-founded Primechain Technologies Pvt. Ltd., a blockchain startup with the mission of "building blockchains for a better world".
I have authored 18 books & whitepapers, I manage the Global Cyber Law Database and Blockchain Security Controls and I maintain the Blockchain Blog on medium.com.
