Experience

Mero Smart Sensor

A LoRa and Bluetooth-enabled ESP32 base station that communicates with smart sensors. The nRF sensors included an occupancy sensor, toilet paper roll sensor, and soap dispenser capacity sensor. The base station was programmed with both peripheral and central modes active simultaneously. The ESP32 was connected to the cloud for data upload using MQTT.

Industrial LoRa Gateway

An STM32MP157-based LoRa gateway communicating with multiple sensors spread throughout a factory. I was the Linux developer, while another developer was responsible for the LoRa nodes. I customized the Yocto-based Linux operating system to fit our in-house designed carrier board. I developed a communication protocol over LoRa to be used between the gateway and nodes. The gateway communicated over UART with the LoRa radio. Aside from periodic heartbeats, the nodes only communicated when they were triggered. Each node had its own time slice to send its payload. I created an update infrastructure to update the main application on the STM32.

NXP IoT MDU

An i.MX8-based IoT MDU with Zigbee, Z-Wave, LTE, 5G, WiFi, Ethernet, and BLE. I was the sole developer working on this project. I customized a Yocto-based Linux OS for the i.MX8 carrier board with various wireless technologies. Most of the wireless radios were Silicon Labs and used their coexistence solution (PTA) to prevent packet collision between the radios. I installed a custom version of Home Assistant to control all radios and provide a UI for IoT device connectivity. The IoT MDU was secured by implementing secure boot and tamper detection through an STM32 microcontroller connected to tamper detection switches.

Nellie Kiosk

This is a battery dispensing kiosk with a 4K display programmed using Qt communicating with an AWS backend. The 4K display was powered by an i.MX8 connected to 6 RTOS boards over CAN, each of which controlled 10 batteries.

Marina Pedestal

A marina pedestal with a small display for user information and ads. The application was programmed in Qt and communicated to an AWS server. The pedestal was programmed with software-controlled breakers to switch between 30A and 50A. It came with electricity and water use measurement circuits for client billing.

Soteria OBD2 Relay

A Python application for collecting information from a car through an OBD2 port and relaying it to a service. The max message delay time was confined to 500 ms. This was done through a 5G connection for low latency delivery.
