Soups Ranjan, director of data and risk science at Coinbase, left the cryptocurrency market after three and a half years.
Ranjan announced his departure Thursday in a tweet and a long blog post in which he wrote:
"Last week marked the end of my tour at Coinbase where I built many systems and teams from the ground up (data, risks, tools, identity). Three and a half years have been exciting and Coinbase is a real rocket to which I am extremely grateful to have had a place at the forefront. "
He added that at Coinbase, he began to like "building things from scratch" and suggested that readers "stay tuned" for his next move.
Ranjan is a member of RiskSalon's board of directors, a monthly roundtable on risk management based in the San Francisco Bay Area, which he co-founded with Nate Kugland, head of data science. at Airbnb. It is unclear whether he made a decision on his next career move.
It is also not known whether Coinbase has filled his post or considered it. Neither Ranjan nor Coinbase responded to the request for comment at the time of going to press.
Linda Xie, former director of Coinbase and co-founder and CEO of Scalar Capital, reacted to Ranjan's announcement. tweeted: "End of an era! It has been a pleasure working closely together over the years."
Risk management in difficult times
According to Ranjan, at Coinbase, he oversaw the risk team, implementing security features for user accounts, tools "to streamline the workflow of legal, compliance, and accounting teams," and managing identity verification and KYC integration. He also led the data science team responsible for automating Coinbase's identity verification and enforcement processes.
In his farewell note, Ranjan noted that in the beginning, Coinbase had "a relatively difficult fraud problem in fraudulent payment due to the instantaneous and irreversible nature of cryptocurrencies". He therefore developed with his team a system of risk scores and machine learning. Mechanisms based on the detection of a client "uses a stolen payment instrument to buy cryptocurrencies".
Another achievement that he cited was the introduction of enhanced authentication at Coinbase, when users need to provide additional proof that they are the ones they claim they want log in when there is a risk of account takeover.
He also recalled the problems faced by Coinbase during the unprecedented Bitcoin rally in December 2017:
"During the 2017 crypto-bull session, we had huge backlogs of identity document verification. We had to refuse several customers. We quickly revised our audit infrastructure and moved from a fully manual process to another automated system that cancels and validates the IDs, then proceeds to the manual process down. "
Ranjan thanked his superiors and colleagues, as well as Coinbase, pointing out that it was now a kind of "crypto university" whose alumni would have enough knowledge to create something new and share their expertise with the community.
