      Smart contract auditor

      I had the opportunity to further develop my skills as a Smart Contract Audit Intern at Hexlant. In this role, I conducted smart contract audits to identify security vulnerabilities and ensure compliance with industry standards and best practices. I collaborated closely with developers to review and improve code quality and security. My responsibilities also included generating detailed reports on findings, assisting in the development of tools and methodologies to streamline the auditing process, and managing databases of smart contract audit reports using MySQL. This hands-on experience provided me with a deeper understanding of the security aspects of blockchain technology and the importance of thorough and meticulous auditing. Show less
