College Station, TX
Developed C++ I2C drivers for Teensy 4.1 avionics sensors, adding 416 Hz IMU FIFO batching, GNSS NMEA parsing, BMP390 barometer data, LiDAR ranging, and INA260 current/voltage sensing.
Coordinated multi-rate polling across dual I2C buses by implementing FreeRTOS scheduling and publishing avionics telemetry through queues/shared snapshots.
Validated Teensy integration by building Raspberry Pi Pico HITL firmware in C for USB-framed injection, checksum validation, shared buffers, and breadboard testing.
Reduced integration risk with 35 native C++ tests using mocked Arduino Wire for IMU FIFO behavior, GNSS parsing, malformed data, stale recovery, and diagnostics.
Debugged I2C/SPI/UART issues with oscilloscope and logic-analyzer captures while leading avionics after promotion from Electrical Engineer to Project Manager.
Validated flight-software drivers on manufactured CanSat PCB hardware using schematic review and datasheet checks to isolate sensor, bus, and power-integration issues.
Tinycardia
Personal Project
Jun. 2025 – Present
Odessa, TX
Developed embedded C firmware on STM32 F446RE to acquire 256 Hz ECG data from MAX30003 over SPI, buffering 10-second / 2,560-sample windows for local AFib inference.
Built a TinyML ECG-classification pipeline using Pan-Tompkins QRS detection, R-to-R features, and a dual-branch 1D-CNN/dense model, achieving 93.68% accuracy and 68.26% F1.
Deployed a quantized AFib model for local ARM Cortex-M inference and streamed ECG/inference data over UART to a Python/PyQt live visualization workflow.
Designed KiCad R2 wearable PCB with Nordic nRF52840 BLE telemetry, ECG AFE integration, battery/power subsystem, USB-C, and phone-facing prototype visualization.
Developed nRF52840 wearable firmware for ECG acquisition, local preprocessing or data streaming, BLE transfer, and phone-facing prototype telemetry.
Validated R2 prototype hardware across ECG acquisition, BLE communication, power behavior, signal routing, and wearable enclosure integration.
EmbeddedSprint
Personal Project
Jun. 2025 – Present
Odessa, TX
Completed a C/C++ STM32 firmware sprint covering GPIO, EXTI, timers, UART ring buffers, SPI loopback, ADC, PWM, and FreeRTOS primitives.
Built FreeRTOS task, semaphore, and queue prototypes using STM32CubeMX, CMake, ST-LINK, gdb-multiarch, tagged Git commits, and custom tests.

Improved latency-sensitive validation by reverse engineering network timing for hitbox tracking and client/server synchronization, reducing reach-detection tolerance from roughly 0.3 blocks to roughly 0.001 blocks.
Built server-side movement validation by brute-forcing input combinations and simulating client movement logic, reaching roughly 1e-8-block uncertainty against observed movement.
Maintained Git/GitHub-managed Java systems software for commercial adversarial-detection clients, isolating validation workload from network threads with roughly 50-user worker pools.
