Full Stack Blockchain & Senior Mobile Developer
With 20 years in IT, I have over a decade of experience developing native Android apps and more than two years in cross-platform mobile development for both Android and iOS.

Passionate about Web3 and its transformative opportunities, I’m excited to bring my skills and experience to innovative projects that drive real value.
