Resume Portfolio

I'm a second-year Mechanical Engineering student at Georgia Tech. My interests lie in robotics, engineering, and rapid prototyping.

Short second line about what you're doing right now, and an invitation: reach out if you're working on something in this space.

Projects

A few I'm most proud of.

Personal Project CFD 325 km/h

300+ km/h Quadcopter Speed Drone

A 3D-printed quadcopter built for top speed from stock 5" parts, with GPS onboard for future autonomous flight. I designed the airframe in SolidWorks around the electronics and camera, then simulated airflow in OpenFOAM from −4° to 13° and 10 to 100 m/s to compare four fuselage shapes. I soldered all the electronics and tuned it in ArduPilot.

  • 325 km/h GPS top speed on the third flight (172 km/h on the maiden, at 48% throttle)
  • 880 g printed in PLA
  • Peak L/D of 9.1 at 5°, and passively pitch-stable
  • 1.0 kW needed at 300 km/h against 3.4 kW installed, so propeller pitch, not drag, sets the ceiling

Personal Project Robotics In Progress

4-Wheel Differential Swerve Robot

A four-wheel robot where every wheel sits in a differential swerve module: two N20 motors both steer and drive each wheel, so the robot can move in any direction while rotating. I modelled it in Fusion 360, 3D-printed every structural part and ran FEA on the gears. A Raspberry Pi 5 handles LiDAR mapping and path planning, while an ESP32 on a custom PCB runs the motors.

  • 4 modules, 8 motors with unlimited steering, since no wires turn with the wheel
  • 12 MPa peak gear stress at motor stall, against about 50 MPa for PLA
  • 88 × 33 mm two-layer KiCad PCB replaces two hand-wired boards, with 0 design-rule errors
  • Next: module testing, closed-loop control and LiDAR mapping
