full-stack shape-shifter · 🦀 systems by day, 🎯 Flutter by night · "我们，有些许相似"

My GitHub display name reads 我心里危险的东西 — The Dangers in My Heart — because, yes, even the profile is anime-coded. 🎀 My bio, 我们，有些许相似 ("we are, in some ways, alike"), is the only spec I really follow: write code that feels familiar to whoever opens it next, stranger or future-self. The load-bearing, invisible kind — the stuff nobody notices until it's gone. 🤝

「云无心以出岫，鸟倦飞而知还。」 "Clouds drift from the peaks without a thought; birds, weary of flight, know the way home." — 陶渊明 ·《归去来兮辞》, via 一言 Hitokoto

Two lessons, both mine: build like the clouds — 无心, effortless, the right thing emerging on its own — and learn the bird's instinct for 知还, knowing exactly when a piece is done and it's time to come home. 🍃 Every repo below is one small return journey on that same mountain. 🏔️

🦀 Daylight belongs to Rust — async runtimes, Axum handlers, zero-cost abstractions that justify every byte they keep around. 🌙 Night flips the keyboard to Dart & Flutter — that's when the passion projects wake up and the fun starts. ☕ I drift fluently across the JVM — Java · Kotlin — and feel equally at home in the kernel-adjacent trenches and the UI treetops. 🌳 🌸 Anime-coded by origin — mikan_flutter, sakura-dmhy, kisssub are exactly what they sound like, and they're the bedrock this whole career was poured on. 💘 🤖 AI as craft, not shortcut — the agents and assistants I build exist to make code measurably better, never merely faster. 🧠 ⛓️ Web3 keeps the brain bendy — BTC, EVM and the Internet Computer each warp your thinking in a worthwhile direction. 🔭 🌱 On GitHub since 27 August 2016 — nearly a decade in, and somehow still the keenest beginner in every room I walk into. 🚀

⚙️ Load-bearing Rust — Axum services whose napkin sketch survives real traffic, not just the demo. 📱 Flutter & the Dart ecosystem — core contributor at FlutterCandies, shipping packages that quietly power thousands of apps. ☕ JVM at scale — Spring microservices architected for production load, not conference slides. 🌐 Frontend craft — React & Vue SPAs that feel instant, stay accessible, and hide a little delight in the corners. 🤖 AI workflows — agents, code assistants and quality gates that amplify human judgement instead of outsourcing it. ⛓️ Web3 tinkering — BTC, EVM chains and the Internet Computer; decentralisation is a muscle worth keeping limber. 🔧 Developer tooling — anything that hands a fellow dev back five minutes a day earns a repository of its own. ⏱️

🗂️ 100 public repositories — tools, apps, libraries and the occasional 3 a.m. experiment ⭐ ~1.7k stars across the featured wall below, with a steady trickle drifting in each week 🌸 1,308 of them live on mikan_flutter — the cornerstone that started it all 👥 282 developers following along, 49 of whom I'm quietly learning from in return 🍬 Core contributor at FlutterCandies — a 128-repo collective followed by 1,900+ builders 🗓️ On GitHub since 27 August 2016 — nearly 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 pulls a live star count, so what you see is exactly what the community feels right now. Tap any of them 👇

🌸 mikan_flutter — the beloved Flutter client for the 蜜柑计划 anime index, now at 1,308 ⭐ 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, spanning Android TV, Apple TV and Fire TV (55⭐). Big screens deserve great UX too. 📺 🎬 sakura-dmhy (37⭐, Java) & kisssub (35⭐, Kotlin) — anime-index clients for dmhy & 爱恋BT, the passion projects where this whole story began. 🌸 ✂️ json_dart — template-supported JSON→Dart codegen (24⭐). Boilerplate, honourably 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 neatly in line. 🔢 ⏳ hora — immutable, type-safe date-time for Dart, inspired by Day.js (18⭐). 🕰️ 📐 flexbox_layout — bring the web's flexbox mental model into Flutter layouts (17⭐). 📦 ⚙️ env2dart — turn a .env file into type-safe Dart code (11⭐). 🔐 ✨ svgo — a powerful SVG optimizer for Dart and Flutter (9⭐). 🖼️ 🛡️ resx — a tiny-but-complete functional error-handling toolkit for Dart: Result, Option, Validation, AsyncResult (8⭐). 🧰 🟦 dotrix — a dot-matrix loading indicator with 28 ready-made effects (8⭐). 💠 🧭 dash_router — zero mental overhead, fully type-safe Flutter routing (7⭐). 🗺️ 🪪 vcard_dart — complete vCard 2.1/3.0/4.0 parsing & generation, with jCard & xCard (3⭐). 📇 🤝 Core contributor at FlutterCandies — a collective shipping battle-tested packages across the Dart ecosystem. 🍬

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 reads on the first pass. Every abstraction pays its rent in clarity, not cleverness 🎯. I write code my future self will thank me for, and code a complete stranger could fall for on day one.

Tests are the safety net 🔒, reviews are the mirror 🪞, and open source is the classroom 🎓. The real art is subtraction: strip the noise away until only the signal remains 📡 — 鸟倦飞而知还, knowing when to come home. Build with conviction, ship with humility, and always leave the codebase a little warmer than you found it 🌸.
