"我们，有些许相似" — We are, in some small way, alike. 🌸

I build across the entire stack — backends that hold their shape under real load, frontends that feel like they're reading your mind, and the patient, invisible glue in between. My compass is simple: ship software that makes someone's day a little faster, a little calmer, or a little more delightful. ✨

• 🧠 Rust thinker by daylight — Axum services, async runtimes, abstractions that cost nothing and survive production. After dark, a relentless Flutter tinkerer. 🌙
• ☕ Equally fluent in Java, Kotlin, TypeScript & Dart — comfortable from the network edge down to the very last pixel. 🎨
• 🌸 Unapologetic anime & gadget nerd. Yes, mikan, sakura and kisssub are exactly the passion projects they sound like — and my display name borrows from The Dangers in My Heart 💘.
• 🤖 Convinced AI-augmented development is a craft, not a cheat code — I build agents and assistants that make code genuinely better, not just faster.
• ⛓️ Permanently curious about Web3 primitives across BTC, EVM and the Internet Computer.
• 🗓️ Committing since August 2016 — closing in on a decade, still shipping, still learning. 🌱

⚙️ Systems-Level Rust — Axum services where whiteboard abstractions hold up against real traffic 📱 Flutter & Dart Ecosystem — core contributor to FlutterCandies, shipping packages used by thousands of apps ☕ JVM at Scale — Spring microservices architected for genuine load, not conference demos 🌐 Frontend Craft — React & Vue SPAs that feel instantaneous, accessible and quietly delightful 🤖 AI Workflows — agents, code assistants and quality gates that amplify human judgment ⛓️ Web3 Explorer — BTC, EVM chains, Internet Computer; decentralization is a muscle worth exercising 🔧 Developer Tooling — if it saves someone five minutes a day, it deserves to exist

From Hitokoto. The whole job, really: don't pretend the bug isn't there, don't dodge the awkward refactor, don't look away from the edge case that bites at 3 a.m. 🌙 Good engineering is stubbornness pointed at the right things — notice everything, flinch at nothing, and fix it anyway.

• 🥇 mikan_flutter — a beloved Flutter client for the 蜜柑计划 anime index, rocking 1.3k+ ⭐ and 60+ forks. Proof a niche tool built with love can outshine a thousand generic ones. 🌸
• ⚡ fjs — a high-performance JavaScript runtime for Flutter, built in Rust on QuickJS. Cross-language interop as a superpower. 🦀
• 📺 dpad — TV & D-pad navigation for Flutter, as simple as native Android development. Big screens deserve great UX too.
• 🧩 void_signals — blazing-fast signal reactivity for Dart & Flutter, based on alien-signals. State management that disappears into your architecture. 🔮
• 📅 hora — an immutable, type-safe date-time library for Dart, inspired by Day.js.
• 🤝 Core contributor to FlutterCandies — a collective shipping battle-tested packages across the Dart ecosystem.
• 🌱 100 repos · ~1.7k stars · 282 followers — grateful for every star and every interesting conversation.

Great software is empathy compiled into code 🧠. The best systems are invisible — they respect your time, anticipate the edge case before it bites, and dissolve quietly into whatever someone is trying to accomplish ✨.

Every function earns its place. 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 that strangers can fall in love with at first read. Tests are my safety net 🔒, reviews are my mirror 🪞, and open source is my classroom 🎓.

The art is in the subtraction: strip away the noise until only the signal remains 📡. Build with conviction, ship with humility, and always leave the codebase warmer than you found it 🌸.
