Indie maker building useful web products

About

Hi, I'm Xingmao, an independent maker focused on simple and useful web products. I'm currently building SandArtAI, which turns photos into AI-generated sand art; Photo to Sticker, a free instant photo-to-sticker maker with 16-expression packs; and RainSleep, a free collection of rain sounds and sleep music for sleep, focus, and relaxation. I enjoy shipping focused products, improving them through user feedback, and connecting with other makers.
