PhD Scientist & R&D Consultant | Industrial Data Analysis & IoT Prototyping

Profile Summary

I bridge the gap between Hard Sciences (Chemistry/Engineering) and Data Intelligence. With 20+ years of experience leading R&D projects for major corporations like Petrobras and Vale, I specialize in solving complex industrial problems. Unlike standard data analysts, I understand the physics and chemistry behind the numbers. My Core Services: Industrial Data Science: I use Python (Pandas/NumPy) to clean, analyze, and visualize complex datasets from industrial processes, lab experiments, and sensors. I turn raw data into statistical insights for decision-making. IoT & Automation: Design and prototyping of intelligent systems using ESP32/Raspberry Pi and MQTT protocols for precision agriculture and lab automation. Chemical R&D: Deep expertise in surface chemistry, lubricants, and nanotechnology (Holder of 3 patents). Technical Writing: High-level reporting, grant writing, and patent analysis. Whether you need to formulate a new product or analyze sensor data from your plant, I bring PhD-level rigor to your project.
