Minimal CBOR encoder/decoder for embedded systems written in portable C99, focused on zero-allocation telemetry and small firmware targets.

ROS 2 host-side agent speaking ROS 1 rosserial wire protocol

ESP32 firmware with a custom LoRa driver and KiCad PCB design for a low-power environmental sensor node built for long-range field telemetry.

Thermostat controller for an ATmega2560 in C, written against the registers with no framework: interrupt-driven ADC, EEPROM setpoints with failsafe defaults, Unity tests on host and target.

An IoT-based PM2.5 Air Quality Monitoring System constructed with the Arduino language, the ESP8266 Node 12-E Microcontroller, & the PMS5003 PM2.5 air particle and dust laser sensor by Plantower. Was used to create a geo-map visualization of collected particulate matter air-quality data of the UTA campus.
