I’m an independent developer based in China with an academic background in cryptography. My interest in AI started from hands-on experiments with training smaller models, which helped me understand how data, model behavior, and system design come together in practice. These days, I’m especially interested in using AI more efficiently: building practical tools, improving workflows, and finding ways to make automation useful without adding unnecessary complexity. I like working on lightweight systems that solve real problems, and I’m always exploring how AI can help independent builders move faster, make better decisions, and turn ideas into usable products.
