About Me

Hi, I'm Rodrigo Lizalde Sanchez — a full-stack software engineer with a passion for building reliable, well-crafted software across the entire stack.

I work primarily in JavaScript/TypeScript and Python, with experience in React, Node.js, PostgreSQL, and AI/LLM integration. I enjoy everything from designing data pipelines to shipping polished UIs. Fluent in English and Spanish, with intermediate Mandarin Chinese.

Outside of work I'm into board games, Magic: the Gathering, video games, and homelabbing. This site runs off my own Ubuntu server — just for fun.
