Every constellation begins as scattered points of light 🔭 — and every good product begins as an iota: one small, sharp idea that refuses to stay small. I'm iota9star, a full-stack developer who draws the lines between those points: high-performance Rust & Java backends ⚙️, polished Flutter frontends 📱, and open-source packages that other people's apps quietly lean on every day 🍬. Nine bright spots in my sky so far — and I'm still connecting them, one commit at a time ✨.

Hi, I'm iota9star 👋 — a full-stack engineer who believes the smallest details decide the biggest outcomes. A misaligned widget, a blocking query, a missing type: none of them look like much until they're all your users talk about. So I obsess over the iotas — and let the stars take care of themselves 🌟.

My natural habitat is the whole stack: Rust 🦀 when every millisecond is the product, Java & Kotlin ☕ when systems need to scale without drama, Dart & Flutter 🎯 when one codebase must shine across phones, desktops and TVs, and TypeScript 🌐 when the browser is the stage. Around all of it, AI 🤖 works as a genuine quality multiplier in my workflow — agents, assistants and review loops that compound every sprint, never party tricks.

After hours, I garden in the open-source orchard with the FlutterCandies community 🍬 — a shelf of published Dart/Flutter packages — plus a fine-grained signals experiment 📡 and a trio of anime clients 🌸 that own a suspicious share of my contribution graph.

🔬 Currently exploring: Rust-powered JavaScript runtimes, fine-grained reactivity, TV-first D-pad navigation, and letting the compiler do my debugging for me 🧠.

• ⚙️ High-Performance Backends — Axum (Rust) & Spring (Java) microservices that stay boring under pressure, the finest compliment infrastructure can earn
• 📱 Cross-Platform Apps — Flutter & Android experiences that feel born on whichever screen they land on
• 🌐 Modern Frontends — React & Vue interfaces shaped by product thinking, not ticket queues
• 🤖 AI-Powered Engineering — agents and quality-first workflows woven into real development, not bolted on
• ⛓️ Web3 Primitives — BTC, EVM & Internet Computer, past the hype and into the mechanics
• 📦 Open Source Packages — small, sharp, published Dart/Flutter libraries, out in the wild 🍬
