Actively modeling a 1600lb thrust, pressure-fed, regeneratively cooled, LOX/Paraffin hybrid rocket for 40,000 feet. Designing a GOX/Propane augmented spark igniter to replace previous unreliable ignition system. Experimenting with helical fuel grain port geometries to increase regression rates.

New York, New York, United States

Constructed a 1200lb thrust, blowdown, paraffin/N2O hybrid rocket for FAR-out competition hitting an apogee of 5,000 feet. Led the design development of a triplet impinging injector and vortex injector to improve regression rates and mixing. Tested injector using pressure transducers and flow sensors to size orifice CdA values to achieve desired mass flow rates. Performed stress analysis and FEA of injector to prevent bolt failure and obtain high safety margins on Solidworks Simulations. Integrated baffles in pre and post combustion zones to induce fuel turbulence to increase out combustion efficiency.

Engineered an 800lb thrust, blowdown, paraffin/N2O hybrid rocket for launch at Spaceport America reaching 2,000 feet. Manufactured the aluminum injector, graphite nozzle, and nozzle retainer using HSMWorks and CNC lathes and mills. Troubleshooted injector issues and assisted in the design of impinging injector.

Lafayette, Colorado, United States

Revamped the valve core design to optimize performance by reducing stress concentrations, specifically targeting future mid and high-pressure iterations. This involved extensive use of Solidworks for 3D modeling and Ansys Mechanical for finite element analysis (FEA) to simulate various operating conditions and identify potential failure points. Additionally, I developed a comprehensive test apparatus to evaluate the functional performance of the valve actuation system under a range of temperatures, applied loads, and operational speeds. This apparatus ensured reliable testing and data collection for further design refinement. I also created highly detailed manufacturing drawings using GD&T principles to ensure precise fabrication, maintain tight tolerances, and meet industry-specific engineering standards.

Weldon, North Carolina, United States

Led the design and construction management of a 90-degree concrete infeed ramp for a sawmill, engineered with an 8% slope to optimize material flow and structural integrity, with a budget of $600,000. Using AutoCAD, I designed the layout and incorporated three custom-fabricated steel log cradles, each capable of supporting up to 60 logs. This involved close collaboration with steel fabricators to meet load-bearing requirements. Additionally, I managed contractors during railroad modifications, overseeing the removal of 100 feet of track, raising the rail bed by 1 foot, replacing deteriorated ties, and coordinating with CSX Transportation to connect to the town's primary rail system. My leadership ensured the project’s timely and successful completion
