Summary
Mechanical engineer focused on product development for mechanisms, enclosures, and electromechanical assemblies. I turn requirements into shipped hardware through evidence-driven prototyping, SolidWorks/ANSYS FEA, supplier-facing DFM/DFMA, and Arena PLM (BOM/ECO), owning design transfer with clean hand-offs and first-article/tooling feedback to meet cost, serviceability, and scale—open to consumer, industrial, and R&D roles.

Experience
Viken Detection — Mechanical Engineer (progressed from Co-op to Full-Time)
Burlington, MA • Jul 2020–Present
Key mechanical designer for a mobile X-ray scanning module from concept to deployment.
Designed carbon-fiber/fiberglass structures and sheet-metal/machined brackets; partnered with fabricators for DFM.
Owned BOM/ECO control in Arena PLM; coordinated design transfer with vendors and vehicle body teams.
Vendor liaison for molded/machined parts: RFQs, tolerance/finish decisions, and first-article/tooling feedback.
Ran SolidWorks Simulation FEA and on-vehicle vibration/road tests; validated durability and stability.
Built Design of Experiments (DOE) for a solenoid-controlled shutter; automated thermal/optical timing tests (Arduino, MATLAB) to confirm timing over extended use.
Supported multi-site field installs [mechanical assembly, wiring, Quality Assurance (QA)]; closed loop with test data for next revisions.
Harvard Microrobotics Lab — Visiting Undergraduate Research Intern (Project CETI)
Boston, MA • Jul 2022–May 2023
Designed next-gen underwater acoustic-tag packaging to improve CG/stability and recording time.
Developed multi-part polymer molding assemblies; documented for reproducible builds and clean lab hand-offs.
Contributed to PCB schematic capture/layout; supported smooth mech-electrical integration.
Ran buoyancy, pressure-resistance, and hydrodynamics tests to improve field performance; earned FAA sUAS Remote Pilot and supported field deployments.
Capstone — Ergonomic Friction-Drive Wheelchair (1st Place in Track)
Northeastern University, Boston, MA • Jan 2023–May 2023
Bolt-on friction-drive assist from concept to functional prototype; sized powertrain/gear ratio; designed serviceable enclosure.
