ι (iota) is the smallest letter in the Greek alphabet — and the smallest things are exactly where big software gets won or lost ⚖️. One sharp function, one honest type, one commit that says what it does: stack enough of those and you get systems people actually enjoy using. I build the fast parts underneath 🦀, the friendly parts on top 🖥️, and the product glue that makes them feel like one thing 🧲.

Hi, I'm iota9star 👋 — a full-stack engineer who refuses to pick a favorite layer, because every layer is someone's favorite. Rust when speed is the feature 🦀, Java & Kotlin when systems need to scale without drama ☕, Dart & Flutter when one codebase has to bloom on phones, desktops and TVs 📱, and TypeScript when the browser is the stage 🎭.

Daytime me ships microservices, cross-platform apps, and AI woven into real workflows 🤖 — as a genuine quality multiplier, never a party trick. After-hours me tends an open-source garden with the FlutterCandies community 🍬: a shelf of published Dart/Flutter packages, a fine-grained signals experiment, and the occasional Web3 detour ⛓️.

🔬 Currently obsessed with: Rust-powered JavaScript engines, signal-based reactivity, D-pad-first TV navigation, and convincing the type system to do my debugging for me.

• ⚙️ High-Performance Backends — Axum (Rust) & Spring (Java); microservices that stay boring under load, which is a compliment
• 📱 Cross-Platform Apps — Flutter & Android experiences that feel native wherever they land
• 🌐 Modern Frontends — React & Vue surfaces shaped by product thinking, not just ticket queues
• 🤖 AI-Powered Engineering — agents, assistants & quality-first workflows that compound every sprint
• ⛓️ Web3 Exploration — BTC, EVM & Internet Computer, past the hype and into the primitives
• 📦 Open Source Packages — publishing small, sharp Dart/Flutter libraries into the wild 🍬

• 🪶 Small, sharp tools beat big, blunt ones — in languages, libraries, and life.
• 🛡️ Type safety is a feature: bugs the compiler catches are bugs users never meet.
• ⚡ Write performance users can feel, and code reviewers can actually read.
• 🔁 Ship, measure, refine — always with the product in mind 🧭.
• 🌱 Open source is how one developer says thank you to thousands.
