Production-grade embedded systems — from schematic review through firmware deployment. Specialized in cellular IoT, low-power wireless, and edge intelligence. Based in Brazil, working globally.
Capstone engineering project: a connected safety helmet combining on-device machine learning inference (TensorFlow Lite Micro), GPS positioning, and LTE-M cellular connectivity via ESP32 + SIM7000G module. Full-stack embedded — firmware in C, custom 3D-printed enclosure (Fusion 360), cloud data pipeline, and mobile visualization.
Firmware and hardware development for a commercial IoT product using ESP32-S3. ESP-IDF based firmware with WebRTC-based real-time communication, I2S codec integration, WiFi/BLE connectivity, MQTT signaling, OTA updates, and EMC-compliant PCB layout review. Currently shipping.
End-to-end IoT alarm and monitoring system built on ESP32. Sensor integration, real-time alerts, WiFi connectivity, and remote monitoring interface. Designed for reliability in continuous operation.
Firmware for ESP32-C2 handling serial communication protocols. Lightweight, cost-optimized design for industrial data bridging applications.
Production PCB design and review across multiple IoT products — codec circuits, LDO power regulation, amplification stages, audio filtering, and 4-layer mixed-signal layouts. Custom 3D-printed enclosures designed in Fusion 360 and sliced with OrcaSlicer for FDM prototyping.
Production-grade C firmware for ESP32, STM32, and Nordic platforms. BLE, WiFi, MQTT, OTA updates, driver integration, and RTOS-based architectures.
Schematic capture and PCB layout for IoT devices. 4-layer mixed-signal boards, power management, EMC compliance, DFM-ready output for JLCPCB/PCBA. Custom 3D-printed enclosures in Fusion 360.
LTE-M/NB-IoT connectivity via nRF9160, on-device ML inference with TensorFlow Lite Micro, and cloud integration (AWS IoT, Firebase, custom MQTT brokers).
Architecture review, component selection, power budget analysis, and technical scoping for IoT product teams. From prototype to production.
I'm a Mechatronics Engineer building firmware and hardware for connected devices. My daily work involves shipping commercial IoT products — from schematic review and PCB layout through firmware development and field debugging.
I specialize in the intersection of embedded systems, wireless connectivity, and edge computing. My capstone project combined TensorFlow Lite Micro with LTE-M cellular connectivity on a custom PCB — a combination that remains rare in the embedded world.
I take on select freelance projects that align with my expertise. If you're building connected hardware and need reliable engineering, let's talk.
Have a connected device that needs reliable firmware or hardware design?
I'm available for select freelance engagements.
