Enmanuel Bran

I’m an IoT Embedded Systems Developer focused on embedded firmware, IoT sensor integration, and turning field data into dependable outcomes. I work with ESP32-based systems and prioritize stability through hardware-level debugging and validation.

In my current IoT Development Projects in Guatemala, I developed ESP32 firmware for RS485/Modbus RTU water level monitoring, including CRC-16 validation and real-world troubleshooting. I also built a LoRaWAN rain gauge node and optimized differential payload transmission to ChirpStack, validating performance against real-time field data.

I’m especially attentive to power efficiency and reliability in remote deployments—implementing deep-sleep power management and NVS-based counter persistence for battery-operated field sensor devices. I’ve also diagnosed and resolved radio connectivity issues (SPI/LoRa wiring, chip detection) and supported GPRS/LTE SIM operations on SIMCom A7672G modules.

Alongside engineering, I bring structured information handling and continuous improvement habits from my recent work in logistics and data administration. I digitized and organized technical records with version control, implemented AI-based tools to streamline data processing, and even developed a PPE management system using web technologies.
