Hi, I'm iota9star 👋 — the handle is a build philosophy: iota (ι), the smallest letter the Greek alphabet will sell you, times nine, aimed at a star ⭐. Big bright things are just small things assembled well, so that's how I work — carve one sharp piece, polish it until it gleams, publish it, repeat 🔁.
Full-stack by trade: Rust 🦀 and Java ☕ below the waterline, Flutter 📱 / React ⚛️ / Vue 💚 above it, AI agents 🤖 in the draft room, Web3 ⛓️ when the covers need to come off. Product mindset throughout — the code exists for the person on the other side of the screen 🎯.

A full-stack developer who treats every problem that bites twice as a candidate for extraction: if it hurt in two codebases, it becomes a package with docs, tests, and a semver promise 📦.

• 🏗️ Boring where it counts — Axum and Spring services tuned so the latency graphs stay flat and the pager stays dark; the excitement belongs in the product, not the infrastructure 😴
• 🍬 12 packages under the FlutterCandies banner — D-pads for TVs, immutable clocks, concurrency limits, honest error types; each one escaped from a real app that needed it 🚪
• 🦀 Rust × Dart bridge-builder — a QuickJS-powered JavaScript runtime living inside Flutter, and alien-signals reactivity ported to Dart; two languages, one friendship 🤝
• 📺 Fan first, engineer a close second — three clients for the anime communities I actually live in (Mikan Project, DMHY, Ailian BT), written in three languages across a decade of fandom 💜
• 🤖 AI-native builder — agents write the first drafts, I direct the edit; the merge button only moves when a human is satisfied ✅
• ⛓️ Web3 with the covers off — BTC, EVM and Internet Computer; I read the protocol source before I believe any whitepaper 🔍

🔭 Currently: pushing the Flutter-embedded JS runtime harder, tuning signal-based reactivity toward zero-cost updates, and keeping a D-pad responsive enough to run a living room from the couch 🛋️.
🤝 My profile bio reads 我们，有些许相似 — "we're somewhat alike." If that lands, we'll get along.

• ⚙️ Backend Architecture — microservices that stay calm at p99 so the on-call phone stays dark
• 📱 Cross-Platform Products — Flutter & Android apps that feel native on whatever screen they land on
• 🌐 Frontend Craft — React & Vue UIs shaped around the person using them, not the ticket queue
• 📦 Package Design — tiny, sharp Dart/Flutter libraries: strict types, honest errors, docs that respect your time
• 🤖 AI-Powered Workflows — code assistants embedded in real shipping loops, quality gates always latched
• ⛓️ Web3 Primitives — BTC, EVM & IC experiments where the source is read before the whitepaper is trusted

📜 "旧时王谢堂前燕，飞入寻常百姓家。" 🕊️ "Swallows that once nested in noble halls now wing into the homes of ordinary folk." — 刘禹锡 Liu Yuxi, 《乌衣巷》 Wuyi Lane ✨ The engineer's footnote: that's the open-source arc in one couplet — ideas raised in specialist halls end up in everyone's hands. Publish the package, and the swallows fly 🪶.

• 🧩 Small is a feature — a library you can read in one sitting is a library you can trust
• 🧠 If a human has to remember it, teach the type system instead
• 🐢 Speed is a feature; predictable speed is a promise
• 🚢 Ship the version that teaches; keep the perfection for the API
• 🪞 Review your own diff as a stranger would — future you qualifies
• 📐 Constraints aren't the enemy of design; they are the design
