full-stack engineer · Rust by daylight, Dart after dark · anime-fueled builder 🌸🦀

I write the quiet kind of software — backends that stay standing when traffic spikes, mobile apps that vanish under your thumb, and the unglamorous plumbing that quietly hands people their evenings back. My favourite code is the kind you never think twice about: it does its job, steps out of frame, and lets the human on the other side get on with theirs. ✨

「一个人的自身越是丰富，就越难以忍受世俗常规的安排。」 🌙 "The richer a person's inner world, the less they can stomach the arrangements of worldly convention." — 叔本华 ·《人生的智慧》, via Hitokoto

I keep this one close as a small permission slip: build the niche thing, name the repo after an anime, pour love into the corners nobody is watching. Convention is the floor you stand on, not the ceiling above your head — and the most interesting code tends to live just past where the template runs out. 🌸

🦀 Rust is my daylight language — async runtimes, Axum handlers, abstractions that earn every byte they refuse to allocate.
🌙 When the lamps come on, the keyboard flips to Dart and Flutter, and the side-projects wake up.
☕ Equally fluent in Java · Kotlin · TypeScript · Dart, and just as content two layers below the framework as two layers above it. 🎛️
🌸 My display name reads 我心里危险的东西 — The Dangers in My Heart — so yes, the mikan / sakura / kisssub repos really are the anime passion projects they sound like. They're also the bedrock this whole career got poured on. 💘
🤖 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 curious about Web3 primitives — BTC, EVM and the Internet Computer each reward a different flavour of thinking. 🔭
🗓️ On GitHub since August 2016 — nearly a decade in, and somehow still the most eager novice in any room I walk into. 🌱

⚙️ Resilient systems in Rust — Axum services whose napkin sketch still survives contact with live traffic
📱 Flutter & the Dart ecosystem — core contributor at FlutterCandies, shipping packages that quietly power thousands of apps
☕ JVM at genuine scale — Spring microservices architected for real load, not for slide decks
🌐 Frontend craft — React & Vue SPAs that feel instant, stay accessible, and smuggle in a little delight
🤖 AI workflows — agents, code assistants and quality gates that amplify human judgement instead of outsourcing it
⛓️ Web3 exploration — BTC, EVM chains and the Internet Computer; decentralisation is a muscle worth keeping limber
🔧 Developer tooling — if a tool gives someone back five minutes a day, it earns a repository of its own

🌸 mikan_flutter — the beloved Flutter client for the 蜜柑计划 anime index, now sitting at 1,307 ⭐ 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⭐, 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 feels discoverable on the first read. 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 a first pass.

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 📡. Build with conviction, ship with humility, and always leave the codebase a little warmer than you found it 🌸.
