🚀 Full Stack Developer · ⚙️ Rust & Java Backend · 🧭 Product Mindset

Building digital experiences across the stack — from high-performance backends to elegant frontends. From the smallest Greek letter (ι) to the stars 🌟: I care about the tiny details that make software feel effortless.

I'm a polyglot engineer who treats the whole stack as one canvas 🎨. I write Rust when performance is non-negotiable, Java & Kotlin when systems need to scale, Dart & Flutter when craft has to land on every screen, and TypeScript when the web is the target.

By day I design microservices, ship mobile apps, and weave AI into real development workflows 🤖 — not as a gimmick, but as a genuine quality multiplier. By night I maintain open-source packages with the FlutterCandies community 🍬 and explore the Web3 frontier ⛓️.

💡 Currently into: signal-based reactivity, JS runtimes written in Rust, TV-friendly Flutter navigation, and type-safe everything.
