Hi, I'm iota9star 👋 In the sky's naming scheme, iota sits far down the brightness list — small, easy to overlook, and absolutely there on every clear night 🌌. That's my whole theory of software: build small, sharp things that actually ship, and let them add up into something people can navigate by.
I work the full stack — Rust & Java backends that stay calm under load, Flutter & React frontends that feel inevitable in the hand — and I sand every rough edge until the thing seems like it was always obvious 🔭.

I'm a full-stack developer with a product mindset 🧠: architecture matters, but so does the half-second after someone taps the button. My favorite transformation is a scratchy production problem cooling down into a small library strangers can adopt with one pub add 📦.

• ⚙️ Backend steady-hand — Rust (Axum) and Java (Spring) microservices tuned for the quiet virtues: flat p99 curves, errors that tell the truth, logs that still parse at 3 a.m. 🌙
• 🍬 FlutterCandies regular — 12 packages, each one born from a real production scrape: TV remotes, type-safe routing, immutable time
• 🦀 Rust in unexpected rooms — a QuickJS-powered JavaScript runtime living inside Flutter, and alien-signals reactivity carried over to Dart ⚡
• 🌸 Fan first, engineer close second — I wrote clients for the anime communities I actually belong to (Mikan Project, DMHY, Ailian BT): three apps, three languages, one decade 📺
• 🤖 AI-native builder — agents do the drafting, I do the directing; the quality gates stay shut until a human signs ✅
• ⛓️ Web3 with the source open — BTC, EVM and Internet Computer; I read protocol code before I believe a whitepaper 🔑

🔭 In the eyepiece right now: pushing the Flutter-embedded JS runtime harder, tuning signal-based reactivity toward bare-metal speed, and keeping a D-pad smooth enough to run a living room from the couch 🛋️.

• ⚙️ Backend Architecture — microservices engineered to stay boring while the traffic graph does something exciting
• 📱 Cross-Platform Products — Flutter & Android apps that feel at home on every screen they land on
• 🌐 Frontend Craft — React & Vue interfaces shaped by product thinking, never ticket factories
• 📦 Package Design — small, sharp Dart/Flutter libraries: strict types, honest docs, zero filler
• 🤖 AI-Powered Development — assistants woven into real shipping, guardrails always on
• ⛓️ Web3 Primitives — wallets, contracts & canisters built to be understood, not just deployed
