Biography

Biography

Over the past four years, r0bert transitioned from elite red team operations, specializing in creating FUD payloads that successfully bypassed industry-leading EDR systems, to becoming a dedicated Web3 security researcher.

At Halborn, he led the EVM audit team for two years, delivering dozens of critical security audits. Currently, as Lead Security Researcher at Spearbit, r0bert has personally audited and secured high-impact protocols including numerous algorithmic stablecoins, lending protocols, decentralized exchanges, AMMs, DAOs and blockchain games.

Utilizing advanced fuzzing tools like Medusa, Echidna and Foundry, r0bert’s audits have protected protocols with millions in TVL. His hands-on expertise extends beyond auditing, with active involvement in smart contract development and bug bounty engagements. Notably, in September 2022, r0bert identified and responsibly disclosed a critical vulnerability in the Beanstalk protocol managing $14 million TVL, effectively preventing a potential exploitation.
