About
Mechanical engineering student at the University of Texas at Tyler (Houston Engineering Center), expected to graduate May 2027. I focus on practical hardware work: building, debugging, documenting, and integrating real systems across robotics, embedded controls, sensor integration, and fabrication.
Mechanical Design & Fabrication
CAD modeling (Autodesk Inventor, Fusion 360, SolidWorks), 3D-printed part design, DXF/laser-cut workflows, prototype planning, and design for fabrication.
Embedded Systems & Firmware
ESP32 and Arduino-based control systems, BLE and Wi-Fi interfaces, I2C/UART sensor integration, OLED displays, motor/servo/relay control, and custom web UIs served directly from microcontrollers.
System Integration & DAQ
Combining mechanical, electrical, and software subsystems into working prototypes — including power-domain design, sensor bring-up, telemetry, and technical documentation.
Projects
Engineering builds covering robotics, embedded controls, BLE protocol analysis, instrumentation, CAD, fabrication, thermal systems, and electromechanical prototyping.
Modular Autonomous Ground Vehicle (MAG-V)
4WD differential-drive rover with a dual-OS, dual-power-supply architecture. Custom-built 2S LiPo payload bus (relay-isolated) and 3S 18650 UPS for main logic and drivetrain. Parallel control via a custom web UI served over Wi-Fi AP mode and Bluetooth Xbox gamepad — all functions fully mapped to both interfaces simultaneously.
BLE Controller Demonstration — Sunrise Medical Empulse R90
Successful ESP32-S3 Bluetooth Low Energy (BLE) controller demonstration for the Sunrise Medical Empulse R90 power-assist wheelchair unit. The handheld prototype connected wirelessly, controlled the R90 during a live seated test, displayed OLED feedback, and required no physical modification to the R90 hardware.
Hybrid Solar and Hydrogen Charging Station DAQ Redesign
Data acquisition (DAQ) redesign contribution for a hybrid solar/hydrogen charging station associated with UT Tyler and Houston Community College Engineering Center of Excellence. Work includes ESP32-based architecture proposal, I2C sensor validation, OLED integration, and thermocouple/power-rail reliability troubleshooting.
Splash Force Water Rocket
Award-winning third-place entry in a school-wide engineering competition. Served as team lead — responsible for MATLAB projectile-motion simulation, Autodesk CFD airflow visualization, 3D-printed PLA nose cone and fin fabrication, and final documentation. Improved flight duration by 49% and velocity by 61% from unstabilized to final launch configuration.
Double-Pipe Heat Exchanger Project
Mechanical engineering heat-transfer project involving heat exchanger theory, experimental setup, data interpretation, report development, reference formatting, and presentation support.
