I'm in this field because I genuinely love coming up with solutions to problems by utilizing software and hardware.

GNOR Autonomous Submarine

UCF Great Naval Orange Race · ESP32 · C++

I was in charge of 3D printing an improved propeller, as well as programming the ESP32 to not only drive autonomously via readjustments but also connect via Bluetooth to my laptop to allow for remote speed and angle modifications.

  • Programmed ESP32 firmware in C++ for real-time propulsion control and Bluetooth command handling.
  • CAD-modeled and 3D-printed a custom propeller blade deployed in UCF's competitive submarine race.

Row-level security gap in Professor Lockin

Professor Lockin · before launch

I caught a row-level security threat in my 55-table schema while self auditing and patched the gap before my site went live.

void saveSettings() {  prefs.begin("gnor", false);  prefs.putInt("servo", servoAngle);  prefs.putInt("speed", motorSpeedPct);  prefs.putInt("time",  runTimeSec);  prefs.end();}
From the firmware: the settings are saved to memory, so they survive between sessions.

Bluetooth settings lost between sessions

GNOR submarine · before testing

I found numerous errors prior to testing that I fixed such as a Bluetooth error that would reset the updated values between sessions instead of just saving it to memory.

  • I took it upon myself to check for any errors that my code could've produced to ensure that nothing could go wrong.
