Evan Mah

Mechanical engineering student at Northeastern, class of 2029. I take hardware from CAD to printed and CNC-routed parts and debug it on the bench. For the firmware and apps around it, I write the specs and test on the device, and AI coding agents write the code.

Looking for a Summer 2027 internship or a Fall 2027 co-op (July–December) in hardware, motorsports or product engineering. Based in Boston, MA.

Solar Tracker Arcade, the exhibit my team built for Cornerstone of Engineering: steer a solar panel to follow a moving LED sun. I took over the MATLAB game code, wrote the servo code, and tuned the LED crosshair and hit tolerances.

Formula SAE: carbon-fiber mold tooling

Northeastern Electric Racing · Aerodynamics subteam, mold tooling · Spring 2026 – present

I make the carbon-fiber molds for the car's body panels and wings: from the CAD model, through CAM and the CNC router, to a mold surface ready for infusion.

  • Generate CAM toolpaths in Fusion 360 and check and fix the G-code before each CNC router cut
  • Model aerodynamic molds for body panels and wings in SolidWorks
  • Machine, assemble and surface-prep multi-piece molds for carbon-fiber vacuum infusion, 5+ so far from digital model to finished mold
  • Cut metal tabs for the car on the waterjet
  • SolidWorks
  • Fusion 360 CAM
  • CNC routing

The team's final pasta truss bridge in the load-testing machine

Pasta Truss Bridge

Jan – Feb 2026 · 5 students, Cornerstone of Engineering (Project 1)

A pasta truss bridge for a LEGO astronaut crossing a 20 cm Mars crevasse. I designed, drew and tested my own Waddell A truss, then helped merge five test bridges into a team design that held about 288 times its own weight, 52% more than our best first bridge and second in the class. It was then disqualified for being too low for the astronaut.

Laser-cut LCD enclosure

Cornerstone of Engineering, AutoCAD lab 4 · Feb 2026

A desk-clock style enclosure for the course's Pico LCD kit, drawn in AutoCAD and laser-cut from MDF. I measured the board at 3.0 mm with calipers and sized every finger joint to it (0.1181 in). One panel is taller so the screen tilts up toward the user, internal brackets hold the PCB, and side and back cutouts reach the LCD pins and power light. Everything is glued except the front panel, which is a friction fit so the LCD can come out. It assembled on the first cut.

Two-part stamp holder

Cornerstone of Engineering, SolidWorks lab 4 · Mar 2026

A lawnmower-shaped stamp handle for the Solar Tracker exhibit, modeled in SolidWorks with lofted, swept and draft features and sized to print in about five hours. I split it into a body and a slot-in handle so it needs less support material. Real lawnmower wheels sit below the body, but a stamp needs a flat bottom, so I modeled the wheels full size and cut them flush.
