The Engineer

I'm a Mechanical Engineering student at the University of Maryland's A. James Clark School of Engineering, maintaining a 3.96 GPA on the Dean's List every semester.

My passion lives at the intersection of design and fabrication — taking concepts from initial sketch or CAD model through to a finished, functional product.

Whether leading a sub-team on an autonomous vehicle project, building and selling custom kayak racks, or modeling bioinspired robotic actuators in a research lab, I bring the same commitment to precision, craftsmanship, and continuous improvement.

Outside the lab I serve as President of Sigma Phi Delta Professional Engineering Fraternity, overseeing 80+ members across all chapter operations.

Engineering Projects

Autonomous Vehicle Jan – May 2025

UMD Over Terrain Vehicle (OTV)

Chassis & Propulsion Sub-Team Leader · Team of 8 · Budget: $350

Led the mechanical design and fabrication of an autonomous vehicle capable of detecting color, measuring object dimensions, actuating a mechanical flap, and completing a timed obstacle course — within a three-month timeline and $350 budget.

A key design challenge: engineering a custom servo-motor-to-wheel interface. Modeled and 3D-printed a custom bracket that constrained the axle, transmitted torque reliably, and fit within the vehicle's dimensions.

  • Utilized SolidWorks to model and 3D-print brackets, wheel hubs, and servo motor attachments
  • Developed 3 design briefs and presentations with technical drawings and mission analysis
  • Nominated for Best Constructed Vehicle Award at the final class showcase

Truss Design Competition

Team Leader · Team of 6

Led a six-person team through the full engineering design cycle for a competition, single-point-load truss. The final structure exceeded the 1,000-pound load target by more than 250% — withstanding over 3,500 lbs.

Selected a modified Howe Truss configuration, differentiating member materials by force type: pine for compression, oak for tension. Member cross-sections were analytically optimized and Gorilla Glue selected for superior shear strength.

  • Modeled truss geometry in SolidWorks; produced dimensioned technical drawings for fabrication
  • Performed structural optimization in Excel — final truss withstood 3,500+ lbs vs. 1,000 lb goal
  • Coordinated weekly team meetings, workload distribution, full design report, and final presentation

VIP Bioinspired Research Team

Bioinspired Advanced Manufacturing (BAM) Lab

Design Team Leader · August 2025 – Present · University of Maryland
Active Research

As Design Team Leader within the Vertically Integrated Projects (VIP) program, I direct a nine-member subteam developing bioinspired soft robotic actuators. The project draws on spider chelicerae kinematics — analyzed through motion capture video and vector-based modeling — to inform the geometry of hydraulic tendon structures fabricated via resin 3D printing.

The team is currently completing the first full-assembly prototype, designed for single-print resin fabrication — integrating all validated tendon and membrane geometries into a unified actuator ready for hydraulic performance testing.

  • Designed hydraulic actuator membrane geometry in SolidWorks; iterated based on FEA and physical tests
  • Fabricated and evaluated resin-printed prototypes across multiple tendon geometry variations
  • Led weekly team meetings and delivered technical progress presentations to faculty advisors
  • Extracted kinematic data from spider chelicerae motion capture for quantitative design input

Rack & Row

Rack & Row

Founder & Designer · May – Aug 2025 · Hinsdale, MA

A small business I founded to design and fabricate custom wooden kayak and paddle board racks built to individual customer specifications. Each rack is fully modeled in SolidWorks — including assembly drawings and custom paddle-holder components — before a single piece of wood is cut. Final products are finished with weatherproof sealant and delivered with 100% client satisfaction.

Each project follows a structured engineering design process: customer requirements gathered first, translated into a SolidWorks model with dimensioned drawings, then executed through fabrication with regular client check-ins.

  • Designed 2×2, 3×1, and 3×2 rack configurations with full assembly and component drawings
  • Engineered a custom paddle-holder arm attachment with dedicated fabrication drawings
  • Managed end-to-end production: sourcing, cutting, assembly, staining, finishing, and delivery
  • Grew business through direct referrals; trained hired staff in tool safety and quality standards

Custom Ski Bench

Personal Build

Custom Ski Bench

Designer & Builder

Designed and built a custom wooden ski bench from recycled ski equipment. The project began with a full SolidWorks assembly model and dimensioned engineering drawings before any material was cut, then progressed through material selection, joinery, and finishing.

The bench incorporates pairs of salvaged vintage skis as both design inspiration and secondary structural material. A key fabrication challenge: integrating the curved ski geometry into a stable, level seating surface — addressed through methodical cuts and layout of materials.

  • Produced a complete SolidWorks assembly model and component drawings prior to fabrication
  • Operated table saw, miter saw, hand drill, and hand tools throughout the build
  • Applied a range of joinery techniques for a durable, aesthetic final product
