Most of what I'm building lives in the LogBook for Devs organization. I'd rather keep things evolving in one place than maintain a static list here.
const leo = {
role: "Software Engineer → Frontend / AI Engineer",
currentFocus: [
"AI-assisted dev workflows",
"Human-in-the-loop systems",
"Internal tooling & DX",
"Frontend as product surface"
],
howIWork: [
"Spec → RFC (optional) → Implementation",
"Clarity over cleverness",
"Systems > isolated features",
"Clarity, maintainability, performance and strategy are trade-offs, not afterthoughts",
"Ship, learn, refine"
]
};Lately I've been structuring things before coding, working with AI (flows, orchestration, usage patterns), thinking about how things feel to use, and building tools that help me (and others) move faster.
In interfaces, I care about motion as communication, experiences that guide you the way games, anime and cinematics do, and micro-interactions that add clarity and a bit of joy.
My AI party: Codex, Claude and OpenCode, plus custom workflows and orchestration (multi-step flows, tools, feedback loops).
