Hawthorne, California, United States

• Designed a welded frame for ultrasonic welding with 5 axes of adjustability capable of withstanding a 6000N load with less than 20µm of deflection in NX, performed structural FEA iteration in Femap and ANSYS
• Proposed and designed a cam lifting mechanism for the weld process with that reduced tolerance stackups and complexity for all other end effectors and assembly stations on the production line
• Modeled the cam system dynamics in python to optimize for cycle time and stress in components, used vision tracking of a prototype cam assembly to verify accuracy and tune the model, saved months of iteration on.
• Responsible for validation of the weld process to balance cosmetics on the part, leak resistance, and cycle time
• Designed a silicone rubber molded seal for the RJ45 ports on the product that withstood IP67 testing, developed a technique to make 3D-printed molds and cast silicone to rapidly iterate on complex seal shapes.

United States

• Designed and iterated on a 20-foot-long glass fiber composite reinforced metal structure which comprised of over two dozen components, optimizing for the lowest price and weight capable of withstanding high inertial.
• Created a master sketch driven assembly of the structure in SolidWorks to allow for rapid iteration and FEA simulations
• Prepared multi-layer composite samples and tested material properties in an Instron machine to validate FEA assumptions
• Performed electromagnetic simulations in COMSOL to characterize magnet demagnetization and match experimental results

Hawthorne, California, United States

• Responsible for the manufacturing of the Crew Dragon high-pressure propellant abort system including process design for orbital tube welding and pressure testing as well as laser scan inspection, defect analysis, and.
• Built breakout Ansys models for weld defect Kt factors, misaligned tube conditions, and out of tolerance tubing assemblies
• Utilized knowledge of GD&T to create and sign engineering drawings for over two dozen externally machined parts
• Worked on process optimization projects and created custom tools designed in NX

Greater Boston Area

• Designed control and power circuits for wireless magnetic resonance charging
• Coordinated with PhD students to construct and troubleshoot systems for object sensing and tracking using resonance
• Analyzed coil design and circuitry with COMSOL to minimize electromagnetic interference
• Optimized SolidWorks models that house the sensing and charging systems
