Rafael Ribeiro

I am an Electronic and Computer Engineer with hands-on experience across IoT systems, data engineering, machine learning, and cloud infrastructure — with a genuine interest in audio electronics and signal processing on the side. I like working across the full depth of intelligent systems: from gateway firmware and network architecture to data pipelines, dashboards, and predictive models.

My most recent work at Casais Group has been building the IoT layer for GoTwin, a Digital Twins platform — designing the gateway architecture and managing the cloud infrastructure on AWS.

I am drawn to applied machine learning and data intelligence, and have worked on problems ranging from dementia prognosis modelling using explainable AI to large-scale NLP-based fraud detection for Brazil's Securities and Exchange Commission (CVM).
