I'm Nicholas, a seasoned Full-Stack Blockchain Developer based in Hong Kong. My expertise lies in developing both web/decentralized applications and AI agents using cutting-edge technology stacks. Ensuring quality and scalability is my top priority in all my projects.

Beyond coding, I'm passionate about exploring AI tools that simplify our daily tasks and expand our knowledge. Whether it's optimizing smart contracts or diving into the latest advancements, I'm always eager to learn and improve.

During my downtime, you'll find me immersed in traveling around the world or strategizing over poker and ricchi-mahjong. Perhaps we can play together sometime! 😊
