Hey, I'm iota9star — a developer who lives at the intersection of performance and polish 🎯. I spend my days crafting high-throughput Rust services 🦀 and resilient Java microservices ☕, and my evenings shipping Dart/Flutter packages through the FlutterCandies collective 🍬.

My journey started in the anime community — building tools to scratch my own itch turned into some of my most popular open source projects 🎌. Now I'm deep into AI-assisted development 🤖, Web3 protocols ⛓️, and making the developer experience delightful for everyone. I believe the best technology is invisible — users should feel the magic, not the machinery 🪄

• 🦀 High-Performance Rust — Axum services with zero-cost abstractions, fearless concurrency, and compile-time safety nets
• ☕ Enterprise JVM — Spring Boot microservices built for real traffic, real scale, and real reliability
• 📱 Flutter & Dart Ecosystem — 12+ packages in FlutterCandies, from reactive signals to layout engines
• 🌐 Full-Stack Web — React & Vue frontends backed by Node.js or Spring, shipped end-to-end
• 🤖 AI-Powered Dev Tools — Agents, assistants, and automation that multiply what one developer can do
• ⛓️ Web3 Explorer — BTC, EVM, Internet Computer — decoding the decentralized future

• 🦀 Connecting Rust's bare-metal speed with Dart's developer-friendly ergonomics through native integrations
• 🧠 Exploring how AI agents and code assistants are reshaping the way we write and think about software
• 🎌 Turned personal anime community tools into widely-adopted open source libraries
• 🔍 Obsessed with developer experience — if it saves someone five minutes, it's worth building

🍃 后天的努力很重要，所以今天和明天先睡觉。 —— 网络 😴

"The day after tomorrow's effort is crucial — so today and tomorrow, rest well first." A reminder that sustainable pacing beats burnout every time 💡

I ship early, simplify relentlessly, and let users guide the refactoring 🌊. The world doesn't need more clever abstractions — it needs tools that work so well they become invisible 🎨.

My favorite code is the code nobody notices. Every function, every module, every system I build exists to serve the experience, not to show off the engineering. And if a weekend hack makes one developer smile, that's worth more than any architecture award 🏅
