Hi, I'm iota9star 🌟 — a full stack developer who treats the whole stack as one canvas 🎨
I shape ☕ Java microservices and 🦀 Rust services by day, then switch to polishing 📱 Flutter apps until every frame feels effortless; the weekend is for sketching reactive state graphs ⚡ or poking at smart contracts ⛓️
I sweat the details users never name but always feel: honest error messages 🧯, empty states with personality 🫧, and latency you can't perceive ✨
Off the clock you'll find me publishing open source candy 🍬 under fluttercandies, coaching AI agents 🤖 to write code humans enjoy reviewing, and writing about it all on Juejin ✍️
