Product Philosophy
"The best products come from questioning everything and building what others think is impossible. My approach combines deep technical knowledge with creative thinking to identify opportunities others miss. From creating music with PC speakers before sound cards existed to generating art with brainwaves, I've always pushed boundaries. My background in casual gaming and digital marketing gives me unique insights into user behavior and viral mechanics, which I now apply to web3 to create products that are not just technically innovative but also incredibly engaging."
