Hey, I'm Leo 👋
Staff Software Engineer · Rust · Distributed Systems · AI Infrastructure · Headless Commerce
20+ years designing and scaling production systems for global companies in e-commerce, fintech, legaltech, and gaming — including platforms serving millions of users.
My background spans full-stack architecture, distributed backend systems, and headless commerce platforms (Shopify Hydrogen/Remix, React, TypeScript, Node.js). More recently, I've been building AI-native systems, integrating LLM agents, retrieval pipelines, and scalable infrastructure using Rust and modern web technologies.
Current Technical Focus
- Rust — Tokio, Axum, high-performance systems
- AI Infrastructure — LLM agents, tool calling, RAG architectures
- Vector Databases & Embeddings — search and retrieval at scale
- Model Context Protocol (MCP) — agent interoperability
- Local LLM Inference — on-device model serving
