ABOUT ME

Bitcoin developer, wallet expert, and blockchain consultant with 20+ years of software development experience and active in the crypto space since 2017. I specialize in wallet architecture, custody models, exchange auditing, and fund recovery.

As part of the eToro crypto wallet team, I contributed to building the company's first crypto wallet and custodian gateway. I have also integrated enterprise-grade solutions from Fireblocks, BitGo, and Chainalysis, and conducted security and compliance audits for exchanges. From day one of the FTX & Alameda collapse, I served as a crypto adviser and remained hands-on throughout the long recovery process of tracing and securing funds.

Currently an early-stage Bitcoin Core contributor through the Chaincode BOSS program (2025), with a growing focus on Miniscript and wallet development.

In addition to consulting, I serve as an Ambassador at the Bitcoin Embassy Tel Aviv, contribute actively to the Bitcoin open-source community, and act as a court-recognized expert witness in blockchain and cryptocurrency cases. I also regularly speak at international conferences (BTC Amsterdam, BTC Prague, Dev++ Riga) on wallets, self-custody tradeoffs, and protocol development.
