Software Engineer building real-time tolling systems and firmware, plus Java and Python integrations and AI features.
BrazilWhat I'm looking for
I maintain and evolve a 20+ year-old real-time tolling system used across Brazil. I also coordinated the rollout for a new customer, covering the team, scope, database, and infrastructure.
My work includes gateways for toll tag operators and real-time vehicle document validation, along with firmware and desktop software for industrial and safety applications. I’ve also contributed to CAN bus data acquisition, PLC and PIC32 firmware, and an analog/digital I/O board delivered to Canada.
I build web and AI features too, including a TypeScript platform on Google Cloud with a conversational assistant using LLM and RAG. In a personal project, I created AI agents for a family plant nursery to assist with sales, register orders, and measure Meta Ads results.
