Hey! I'm iota9star — a developer who lives at the intersection of systems engineering and product design 🎯. My days are spent building resilient backends in Rust 🦀 and Java ☕, my evenings shipping Flutter apps and maintaining packages in the Flutter Candies ecosystem 🍬, and my weekends exploring Web3 protocols and AI-powered dev tools 🤖.

I'm also a big anime fan — some of my most popular open source projects started as personal tools for the anime community 🎌. I believe great software should feel like magic: invisible infrastructure powering delightful experiences ✨

• 🦀 Rust Systems — High-throughput backends with Axum, zero-cost abstractions, and fearless concurrency
• ☕ Java Microservices — Production-grade Spring services built for real-world traffic
• 📱 Flutter & Dart — Cross-platform apps with buttery-smooth animations and native feel
• 🌐 Full-Stack Web — React and Vue frontends backed by Node.js and Spring
• 🤖 AI Workflows — Agents, code assistants, and automation that amplify developer productivity
• ⛓️ Web3 Explorer — BTC, EVM, Internet Computer — decoding the decentralized future

📜 欲买桂花同载酒，荒泷天下第一斗。 —— 原神

Every great developer was once a beginner who refused to quit 🌟

I choose simplicity over cleverness, shipping over perfecting, and empathy over ego 🌊. In a world addicted to over-engineering, I build the simplest thing that works — and refactor when reality tells me what it actually needs.

Every abstraction I write exists to serve the user, not to impress the next reader. The code I'm proudest of? The code that disappears behind the experience it creates 🎨
