ι (iota) is the tiniest letter of the Greek alphabet — and my daily reminder that small things decide big outcomes 🎯. One symbol flips an equation; one commit can flip the fate of a codebase. I build digital experiences across the whole stack: high-performance engines underneath, elegant surfaces on top, and product thinking gluing it all together 🧲.

I'm a polyglot engineer who refuses to pick a side of the stack 🎨. Rust when every microsecond counts, Java & Kotlin when systems need to scale gracefully, Dart & Flutter when the same craft has to land on every screen, and TypeScript when the browser is the stage.

Daylight hours go to microservices, cross-platform apps, and weaving AI into real engineering workflows 🤖 — as a genuine quality multiplier, never a gimmick. After hours I maintain open-source packages with the FlutterCandies community 🍬, experiment with signal-based reactivity, and poke at where Web3 is actually useful ⛓️.

🔬 Currently obsessed with: JavaScript engines written in Rust, fine-grained reactivity, TV-friendly Flutter navigation, and making the type system do the debugging.

• ⚙️ High-Performance Backends — Axum (Rust) & Spring (Java); microservices that stay calm under load
• 📱 Cross-Platform Apps — Flutter & Android experiences that feel native wherever they run
• 🌐 Modern Frontends — React & Vue interfaces shaped by real product sense, not just specs
• 🤖 AI-Powered Engineering — agents, code assistants & quality-first workflows that compound
• ⛓️ Web3 Exploration — BTC, EVM & Internet Computer, beyond the hype cycle
• 📦 Open Source Packages — a whole shelf of published Dart/Flutter libraries 🍬

• 🪶 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.
