I build across the whole stack: Rust & Java services that hold up under real load, Flutter & web frontends that feel instant, and the quiet tooling in between that hands people their time back. The best code I've ever shipped is the kind nobody ever notices — it just works, and then it gets out of the way. ✨🌸

🦀 Rust runs my daylight — async runtimes, Axum handlers, abstractions that earn every byte they don't spend. When the sun goes down the keyboard quietly flips to Dart and Flutter. 🌙 ☕ Fluent across Java · Kotlin · TypeScript · Dart, and just as happy two layers below the framework as two layers above it. 🎨 🌸 My GitHub display name is 我心里危险的东西 — The Dangers in My Heart — and yes, the mikan / sakura / kisssub repos are exactly the anime passion projects they sound like. 💘 🤖 I treat AI-augmented development as a craft, not a shortcut — the agents and assistants I build exist to make code measurably better, never merely faster. 🧠 ⛓️ Endlessly nosy about Web3 primitives — BTC, EVM and the Internet Computer each reward a different kind of thinking. 🔭 🗓️ On GitHub since August 2016 — nearly a decade in, and somehow still the most excited beginner in any room. 🌱

⚙️ Resilient systems in Rust — Axum services where the whiteboard design still survives contact with live traffic 📱 Flutter & Dart ecosystem — core contributor at FlutterCandies, shipping packages that quietly power thousands of apps ☕ JVM at genuine scale — Spring microservices architected for traffic, not for slide decks 🌐 Frontend craft — React & Vue SPAs that feel instant, stay accessible, and secretly delight 🤖 AI workflows — agents, code assistants and quality gates that amplify human judgment instead of replacing it ⛓️ Web3 exploration — BTC, EVM chains and the Internet Computer; decentralization stays a muscle worth keeping limber 🔧 Developer tooling — if it hands someone back five minutes a day, it deserves a repo of its own

🗂️ 100 public repositories — tools, apps, libraries and the occasional 3 a.m. experiment ⭐ 1,676 stars across the featured wall alone, and climbing every week 👥 282 developers following along, with 49 keeping me honest in return 📝 10 public gists — scratchpads, snippets and half-formed ideas 🗓️ On GitHub since August 2016 — almost ten years and still counting

A masonry of what I'm proudest of — auto-sorted by ⭐ community love and refreshed on every build. Each card is a doorway; walk through any of them 👇

🌸 mikan_flutter — the beloved Flutter client for the 蜜柑计划 anime index, now past 1,305 ⭐ and still climbing. Proof that a niche tool, poured full of love, can outshine a thousand generic ones. 🦀 fjs — a high-performance JavaScript runtime for Flutter, forged from Rust on QuickJS (97⭐). Cross-language interop, treated as a superpower. 🎮 dpad — Flutter TV & D-pad navigation that feels as fluid as native Android (55⭐). Big screens deserve great UX too. 🎬 sakura-dmhy (37⭐) & kisssub (35⭐) — anime-index clients in Java and Kotlin, the passion projects where this whole story began. ✂️ json_dart — template-supported JSON→Dart codegen (24⭐). Boilerplate, retired. 🔮 void_signals — blazing-fast signal reactivity for Dart & Flutter, built atop alien-signals (23⭐). State management that dissolves into your architecture. 🎯 f_limit — a Dart port of p-limit for taming async concurrency (19⭐). Futures, kept in line. ⏳ hora — immutable, type-safe date-time for Dart, inspired by Day.js (18⭐). 📐 flexbox_layout — bring the web's flexbox mental model to Flutter layouts (17⭐). 🤝 Core contributor at FlutterCandies — a collective shipping battle-tested packages across the Dart ecosystem. 🍬

「行远自迩，登高自卑」 — to go far, start near; to climb high, start low. It's the oldest piece of engineering advice there is, and it's still the truest. 🌱

Great software is empathy, compiled 🧠. The best systems are the invisible ones — they respect your time, quietly anticipate the edge case before it bites, and dissolve into whatever someone set out to accomplish ✨. Every function earns its keep. Every API feels discoverable. Every abstraction carries its weight in clarity, not cleverness 🎯. I write code my future self will thank me for, and code a total stranger could fall in love with on the first read.

Tests are the safety net 🔒, reviews are the mirror 🪞, and open source is the classroom 🎓. The art is in the subtraction: strip the noise away until only the signal remains 📡. Build with conviction, ship with humility, and always leave the codebase a little warmer than you found it 🌸.
