Hi, I'm Marco Widjaja, a Product Manager and Web3 builder passionate about DeFi and bringing the world on-chain. I graduated from University of Hong Kong with a Bachelor's degree in Computer Science (1st Class Honors). I worked at Shopee as a PM, where I led initiatives across user growth, authentication, and platform infrastructure. After 3.5+ years, I left to pursue a path of building, creating products at the intersection of DeFi and AI.
Since then, I've built multiple finalist projects recognized by ETHGlobal and Token2049 , including 1Option, a decentralized options protocol, and MicroPay, a cross-chain micropayments framework for AI agents. I also completed Uniswap Hook Incubator (UHI7) , where I built Stealthfolio , a Top 8 finalist project presented in Demo Day.
Beyond tech, I co-run Mercury Sportswear, a golf apparel brand blending sport, design, and entrepreneurship.
I build products with empathy for users and curiosity for what lies at the edge of innovation.
