With 20+ years of experience—from my first Amstrad CPC464 to building modern AI-driven architectures—I solve problems by blending clean archictectures with practical automation.

🤖 AI & Innovation

I don’t just chat with AI; I build systems that integrate it into the development lifecycle.

  • Work Diary: An open-source CLI tool to automate daily work summaries using Gemini/OpenAI and GitHub activity.
  • Sireno AI: A browser extension that brings LLM-powered text correction and translation to any web form.
  • Computer Vision: Early PoC of webcam virtual backgrounds using TensorFlow.js (tfjs-bodypix).
  • AI for CAD: Using LLMs to assist in designing 3D-printed physical items.

🏗️ Design Systems & UX

Expert in creating scalable UI libraries and complex data visualizations.

  • Factorial f0: Core contributor and tech lead (until March 2026) to the Factorial Zero Design System, building robust React/TypeScript components.

🏠 IoT & Open Source

I enjoy bridging the gap between software and the physical world.
