I'm Eric. I'm currently working as a Software Engineer at Studio.init(), building an AI-powered interior design tool from 0 to 1.

Looking back on my career, I’ve been driven by making impacts. In 2021, I entered the blockchain space and started to contribute to Cardano Blockchain, which led me to become a Cardano Ambassador.

At Purchains, I organized the official Cardano Summit and workshop in Taiwan, growing the local blockchain community. I continued working on impactful projects at XFORGE Studio, where I built a scalable NFT minting platform that enables anyone to create digital assets without writing code.

At Studio.init(), I’ve brought that same mindset to AI, focusing on building products that solve real problems from the 0 to 1.
