Full-Stack Engineer · Rust 🦀 & Java ☕ Backends · Flutter & Dart 🐦 Craftsperson Translating caffeine ☕ and curiosity 🔍 into services that scale and apps that feel effortless. 🚀

Hey! 👋 I'm iota9star — a builder who refuses to pick a lane between raw performance at the metal and delight at the pixels. 🧠⚡

I think of a product as one continuous story: a tidy API contract, sub-millisecond latency, animations that feel alive, and developer ergonomics that make the next person smile. 😊 By day I design resilient, high-throughput backends in Rust and Java; after hours I ship polished Flutter apps and Dart packages into the open-source wild.

• 🔭 Right now: crafting fast, observable services with Rust (Axum) and fault-tolerant microservices with Java/Spring. ⚙️
• 🌱 Digging into: the frontier of AI agents, Web3 primitives, and dev tooling that quietly removes friction. 🤖
• 🍡 Off duty: lost in anime seasons 🎌 — a love that quietly spawned several of my most-starred projects!
• ⚡ Mild brag: a flagship repo past 1.3k ⭐, with roughly 1.7k stars earned across everything. 🌟
• ✉️ Inbox open: always up for a chat about systems, Flutter, or a wild side project — say hi! 💬

• ⚙️ Backend Engineering — observable, fault-tolerant services in Rust (Axum) & Java (Spring), built to scale.
• 📱 Cross-Platform Apps — native-feeling experiences with Flutter, Android, and modern web. 🌐
• 🤖 AI Workflows — weaving LLM agents & code assistants into real dev pipelines, quality-first always.
• ⛓️ Web3 Primitives — exploring BTC, EVM, and IC, one building block at a time. 🔗
• 🎨 Open Source — maintaining a constellation of libraries in the FlutterCandies collective. ✨

Sorted by ⭐ popularity — from an anime-season tracker 🎌 to a Rust-powered JS engine 🦀 and a whole galaxy of Flutter tooling. 🌌

📜 "Make it work, make it right, make it fast." — Kent Beck 🛠️ 🌏 Because shipping is a verb with three tenses — and only the last one earns the ⚡.

• 🥇 1.3k+ ⭐ on mikan_flutter — a beloved third-party client for the Mikan Project anime index. 🎌
• 🦀 Shipped fjs — a high-performance JavaScript runtime for Flutter, written in Rust on QuickJS. ⚡
• 📺 Built dpad — D-pad navigation for Flutter TV apps, as simple as native Android. 🕹️
• 🔄 Created void_signals — a blazing-fast signal reactivity library for Dart/Flutter, based on alien-signals. 🛸
• 🧩 Curate a constellation of Dart/Flutter packages in the FlutterCandies collective — routing, signals, concurrency, date-time, SVG tooling, and more. ✨

🚧 Pushing the Flutter + Rust boundary 🦕, weaving AI agents into real dev pipelines 🤖, and quietly chipping away at Web3 primitives across BTC / EVM / IC 🔗. Always one experiment away from the next repo. 🧪

💭 "Clarity first, speed second, cleverness never." I optimize for the API I'd want to call and the UI I'd want to tap. Code should read like prose 📖, ship like a rocket 🚀, and age like a good library. 🏛️
