Rogério M.

Electrical Engineering undergraduate (final year, expected Dec 2026) at the Federal Institute of Sao Paulo (IFSP) with hands-on industrial experience in electronic hardware diagnostics, microcontroller firmware (ESP32, C/C++), mathematical simulation (MATLAB/Simulink), machine learning (Python/MATLAB), and full-scale AutoCAD electrical engineering design.

WHAT I DELIVER FOR YOUR ENGINEERING TEAM OR PROJECT:
• AutoCAD Electrical Drafting & Design (NBR 5410 / NBR 5419 / IEC 60617 / NR-10 / NR-12): Single-Line Diagrams (SLD), Three-Line Diagrams, Control & Interlocking Schematics, Panel Layouts, Bill of Materials (BOM), and Cable Schedules.
• Power Systems & Substations: Medium-Voltage Substations (13.8 kV / 500 kVA, ANSI protection 50/51/50N/51N), Standby Diesel Generator Systems (250 kVA with ATS), Grounding Grids, and Lightning Protection (SPDA).
• Industrial Automation, Drives & Renewables: PLC Control Panels (24 VDC, Digital/Analog 4-20 mA I/O), Motor Control Centers (MCC), VFD Pumping Stations, P&ID Instrumentation Diagrams, Grid-Tie Solar PV Permit Packages, and EV Charging Stations.
• Simulation, Embedded IoT & Software: Induction motor drives (Scalar V/f vs Field-Oriented Control - FOC in MATLAB/Simulink), ESP32 firmware (Wi-Fi, BLE, MQTT) + Android (Kotlin), Digital Image Processing & CNNs (MATLAB), Neural Networks from scratch (Python/NumPy), Modern C++17 (CMake), and Java Desktop Apps.
