About

Embedded systems architect with extensive experience designing, developing, and mass-producing mission-critical electronic products for the energy, utilities, security, and oil & gas sectors.

I've successfully delivered 8+ commercial hardware products currently deployed at scale across hundreds of field units. My work spans the full product lifecycle — from concept and R&D, through circuit design and PCB layout, to firmware development and mass manufacturing.

Core expertise:
- Microcontrollers: ESP32, STM32, ARM Cortex, Arduino
- PCB Design: from schematic to production-ready Gerbers
- Firmware: C/C++, FreeRTOS, OTA remote updates, MQTT, device drivers
- Communication: LoRa, BLE, Wi-Fi, Cellular (2G/3G/4G), Satellite, VHF, RS485
- Sensors: Ultrasonic, seismic, acoustic, optical, temperature, pressure, current/voltage
- IoT & Cloud: AWS IoT, MQTT, web dashboards
- Power: Solar, ultra-low power design, battery management, energy harvesting

All my firmware deliverables include a built-in OTA (Over-The-Air) update system with a web-based MQTT management interface — fully developed and field-tested across hundreds of devices.

Highlights:
- 3 technology patents (gas metering, ultrasonic measurement, optical coding)
- Petrobras Inventor of the Year award
- National Innovation Award (CNI - Brazil)
- International publication (Society of Petroleum Engineers)
- Postgraduate specialization in Artificial Intelligence

I deliver production-ready solutions — not just prototypes.

Experience

CTO & Principal Systems Architect Nastek Technology · Full-time Jun 2003 – Dec 2023 20 yrs 6 mos Brazil Led the full lifecycle of 8+ mission-critical hardware/software products for the energy, utilities, security, and oil & gas sectors. Responsible for system architecture, circuit design, PCB layout, firmware development, and scaling products to mass manufacturing.

Key products delivered:

- IP67 Rugged Tablet with VHF/Satellite/3G — adopted by São Paulo Military Police and utility field teams.
- IoT Armored Safe with proprietary optical coding (15M codes/sec), seismic and acoustic sensors — thousands of units deployed.
- Smart Grid Monitoring System (OWL Sensor) — real-time power grid monitoring with LoRa mesh, 4G, and satellite connectivity.
- Bio-inspired gas flow measurement system for Petrobras — earned Inventor of the Year award and 2 patents.

Technologies: ESP32, STM32, ARM Cortex, C/C++, FreeRTOS, LoRa, BLE, Cellular, Satellite, VHF, PCB Design, MQTT, AWS IoT.

Education

Faculdade Exame Postgraduate Specialization, Artificial Intelligence 2023 – 2024 Advanced studies in applied AI, machine learning, multi-agent systems, and LLM integration for business and industrial applications.
University of Northern Paraná Bachelor's Degree, Electrical Engineering 1998 – 2003 Activities and Societies: Electronics Research Lab Focused on analog/digital electronics, microcontroller programming, circuit design, and power systems. Coursework included embedded systems, signal processing, telecommunications, and control engineering.

Other experience

Web Development, SaaS & Application Design Beyond hardware and embedded systems, I also have hands-on experience in full-stack software development:

- Web Design & Development: Responsive websites, landing pages, and corporate portals using modern frameworks
- SaaS Platforms: End-to-end development of cloud-based software-as-a-service applications, including user authentication, subscription management, and API integrations.
- Mobile & Desktop Applications: Cross-platform apps for device management, data visualization, and remote monitoring of IoT systems.
- Dashboards & Data Visualization: Real-time web dashboards with MQTT, WebSocket, and REST API integration for monitoring sensor data, fleet tracking, and industrial metrics.

This full-stack capability allows me to deliver complete end-to-end solutions — from the hardware and firmware all the way to the user-facing web interface and cloud backend.
