About Me

As a lawyer at Sonmez + Partners, I provide legal services to clients in various sectors, including internet technologies, e-wallet payment systems, system networking, and data security. I combine my legal knowledge and experience with my passion for technology—especially artificial intelligence and cryptocurrency—to offer the most up-to-date and innovative solutions.

I hold three licentiate degrees in law and business administration from prestigious universities, complemented by hands-on experience in software development and blockchain engineering. As the Founder and Managing Partner of Sonmez Partners Law Firm in Turkey and Principal at Sonmez Consulting in the United States, I leverage my multidisciplinary expertise to deliver innovative solutions at the intersection of law and technology.

My unique combination of legal expertise and technical proficiency in Solidity smart contract auditing positions me at the forefront of the rapidly evolving intersection of law and blockchain technology. I am a member of the Istanbul Bar Association and hold certifications in anti-money laundering compliance.

My work contributes to the national interest by developing open-source compliance tools that help protect the U.S. financial system from cryptocurrency-based sanctions evasion, money laundering, and terrorist financing—areas identified as priority threats in the 2024 National Strategy for Combating Terrorist and Other Illicit Financing.
