Passionate and results-driven Senior Backend Developer with over 20 years of experience in designing, developing, and securing enterprise applications. Adept at building scalable, high-performance backend systems using C#, .NET Core, microservices, and cloud solutions. Strong focus on AppSec.

Enthusiastic about Web3 and Blockchain technologies, I am deeply engaged in continuous learning and exploration of this rapidly evolving field. Actively participating in online communities, events, and hackathons, I am dedicated to expanding my knowledge and contributing to the Web3 ecosystem.

While I haven't yet worked professionally in Web3, I have been dedicating significant time to studying and learning about its technologies and applications. I am actively seeking opportunities where I can apply my acquired knowledge and contribute to innovative Web3 projects.

Self-taught and driven by curiosity, I am passionate about science, particularly astronomy. Married with two children, I strive to balance my professional and personal interests.
