Hi, my name is Joaquin Tornello

And I live to code

I'm a senior fullstack engineer focused on AI agents, design systems, and performance. I build production React + TypeScript interfaces, and the Node/Python services behind them—turning docs, components, and workflows into tools teams can actually ship with.

About Me

Hello! I'm Joaquín, a senior engineer who builds products for two users: customers and developers. My sweet spot is where design systems, performance, and AI workflows meet—shipping interfaces that feel simple while the engineering stays solid.

Today I work on AI-powered tooling around a component design system: natural-language search, agentic workflows, and developer experience improvements that remove friction from shipping UI—without compromising accessibility or quality.

I care about clean architecture, predictable releases, and codebases that scale with teams. Outside work, I mentor developers through FrontendCafé and keep my creative side alive as an orchestra musician.

Here are a few technologies I work with regularly:

  • TypeScript
  • React
  • Astro
  • Next.js
  • Node.js
  • NestJS
  • Python
  • LangChain / LangSmith
  • RAG + embeddings
  • Redux Toolkit
  • Testing (Playwright/Vitest)
  • Accessibility + Design Systems

Featured Work

Nimbus MCP project preview

Featured Project

Nimbus Design MCP

An end-to-end AI agent that makes Nimbus Design System knowledge usable in natural language—answering questions and surfacing the exact component guidance—powered by a vector-database RAG pipeline that keeps fast-moving docs embedded, versioned, and always retrievable. With IDE MCP access, developers get Nimbus documentation in the flow, reducing context switching and speeding up correct, consistent UI implementation.

  • React
  • TypeScript
  • Python
  • RAG/Search
  • MDX

Featured Project

Mask on click

An interactive Segment Anything-powered extension for Stable Diffusion Web UI that turns simple clicks into pixel-accurate masks, making inpainting and object-level edits (like swapping clothing) fast, intuitive, and repeatable through a lightweight Gradio UI.

  • Python
  • PyTorch
  • Computer Vision
  • Deep Learning
  • Generative AI
