Building the
future with
AI & Code
I'm Antonio Spagnol — a Software Engineer, AI Automation Entrepreneur, and IT Instructor based in Brazil with my sights set on the European tech sector.
From founding PreencheAI (an AI document automation startup) to teaching the next generation at SENAI, I combine technical depth with a passion for building things that matter. My Digital Brain approach — powered by Obsidian and MCP — keeps my knowledge interconnected and ever-growing.
Currently pursuing a Dual MBA in AI & Big Data and Cybersecurity & Risk Management, I'm constantly expanding my expertise to tackle the most challenging problems in tech.
