About

After several years as a traditional software engineer working with .NET technologies, I transitioned to Web3 and blockchain development, driven by a desire to work on more innovative projects in decentralized finance and digital assets. As a remote-first developer, I've collaborated with cutting-edge projects and diverse teams across the globe.

While blockchain development is my primary focus professionally, I spend my personal time building practical web applications and exploring new technologies.
