About

Who I am

I'm a Full-Stack & Systems Engineer based in Rio Grande do Sul, Brazil, with a strong track record of leading critical engineering initiatives across enterprise environments — from legacy system migrations and cloud architecture to on-site industrial automation deployments.

I've worked across four continents (South America, Europe, Asia, and Africa), solving high-stakes production issues and designing scalable systems that support thousands of daily operations.

Beyond engineering, I bridge technical execution with executive strategy — regularly presenting roadmaps to C-suite and VP-level stakeholders.

With the Alliance One team in Turkey. Solving production issues side by side builds the kind of trust that no amount of remote calls can replace.

Architecting a tobacco-purchasing automation system driven by PLC bale queues, industrial scales, scanners, and printers — rolled out across five Argentine states with 50+ operators per region, integrated with ARCA-AFIP through a high-security SOAP layer.

Pedro is an incredible collaborator and a real pleasure to build alongside. What stands out about him isn't just his engineering skill, which is strong, but the way he works with a team. He communicates clearly, asks the right questions, and stays engaged with the bigger picture rather than just the ticket in front of him. He's responsive, reliable, and easy to align with, which makes complex projects move smoothly even when requirements shift. Pedro brings a steady, constructive energy that lifts everyone around him, and he's the kind of person who makes the whole project better by being part of it. If you're looking for someone who delivers solid work and is a genuine joy to partner with.
