About Luis Vargas

I’m a designer who codes. I started as a motion designer, moved into 3D and character animation, and later into product work that blends research, data, and craft. My path runs through agencies, TV stations, production houses, and software companies. I studied computer science before graduating in graphic design, so the technical side never feels far away.

I play ping pong a lot. I used to play more baseball; now it’s mostly ping pong and walking my dog, Cookie. I have a woodworking setup I swear I’ll use this weekend, and an audiobook habit so strong my bookshelf is basically a pair of headphones, coding, designing, or walking Cookie, there’s usually a book playing.

Personal project

Waco3.io is a proposal/quote/invoice generator for creatives in Latin America. It started as a small experiment while I was a product designer working closely with developers, and it grew into something real. I built it in React and Node, then rewrote it with Claude Code, Codex, and Gemini CLI. The backend bridges AI to the app so responses match the product’s data and tone, using RAG patterns, fine-tuning, and structured prompting. It’s my lab for learning, writing better CSS/JS, and trying new ideas fast.

What I’m exploring now

AI frameworks like Claude Code and OpenAI tools, WebAssembly experiments, and cron jobs wired to MCP servers and APIs so terminal-first AI can watch services and trigger smarter alerts. Always looking for ways to make complex things feel simple.
