About Me

With more than 26 years of experience in software engineering, education, and technical leadership, I specialize in blockchain security, smart contract development, and DeFi protocol architecture.

My programming journey began in the 2000s with algorithms, followed by years of experience with Pascal, Delphi, FoxPro, C++, C#, Java, PHP, JavaScript, ASP.NET, MySQL, and many other technologies. Throughout my career, I have developed real-world software solutions, led technical teams, and continuously adapted to emerging technologies through self-learning and hands-on engineering.

I started teaching computer and software engineering courses in 2005 and have since taught at universities, colleges, private institutes, and online platforms for more than 21 years. My teaching experience includes programming, web development, blockchain technologies, software architecture, graphics software, and engineering tools. I have also authored several educational books and trained hundreds of students and developers.

Since 2008, I have worked as a CEO, CTO, Full-Stack Developer, and Technical Advisor for numerous companies, startups, and Web3 teams across software engineering, blockchain, and decentralized technologies. Over the past several years, my primary focus has been blockchain security engineering, smart contract auditing, and DeFi protocol analysis across Ethereum-based ecosystems.

I specialize in Solidity development, smart contract security, gas optimization, attack surface analysis, vulnerability assessment, and secure DeFi architecture. I also work extensively with modern auditing tools and security methodologies to help teams build safer and more resilient decentralized applications.

Today, I work as a Smart Contract Auditor, Solidity Developer, Blockchain Security Engineer, and educator — combining deep technical analysis with clear communication and developer-focused security solutions.
