- Drafted and optimized technical documentation for Standard Operating Procedures (SOPs) and Work Instructions (WI) related to part fabrication, integration and mechanical testing, ensuring compliance with ASTM and customer standards. - Supported manufacturing duplication efforts by replicating tools, fixtures and molds using SolidWorks, validating functionality and streamlining the transition to a sister facility. - Processed purchase orders for tools, compression molds, salt core molds and fixtures to support duplicate manufacturing operations, ensuring timely procurement for production needs. - Collaborated cross-functionally with engineers and technicians to refine manufacturing processes, ensuring quality and consistency across production lines. - Produced Engineering Change Orders (ECOs) for drawing updates and modifications, ensuring design accuracy and compliance with customer and production requirements.

- Performed comprehensive mechanical testing, including tensile, elongation, tear, brittleness and compression tests on aviation and aerospace materials to collect data and gain insight on material’s mechanical properties. - Conducted ash testing to determine inorganic residue content and fuel immersion testing to assess resistance to aviation fluids.

- Reduced labor costs by 3% by analyzing live sale reports and adjusting employee’s schedule based on daily sales. - Drafted spreadsheets to manage inventory on a weekly basis.

- Drafted conceptual designs and modeled cement torpedo anchors via Rhino 7 to optimize embedment efficiency. - Assisted in the maintenance and calibration of the 3D printer robotic arm. - Conducted research on offshore and land wind turbines, torpedo anchors, and other concrete additive manufacturing solutions. - Assisted in the overall cement 3D printing process.

- Supported in design layouts, duct sizing, and determining system size for commercial and residential buildings via trace 3D. - Aided in troubleshooting and repairing system malfunctions to maintain optimal operational levels utilizing multimeters, manifold gauge set, brazing and soldering equipment and other diagnostic tools.

- Coached students on successful studying strategies/skills and time management. - Administered group tutoring sessions and reinforced basic concepts via zoom meetings and in person.

- Operated Toro Lynx Central Control irrigation system to manage over 1,700 sprinkler heads. - Analyzed system reports to determine the capacity of the system in an effort to strategically schedule sprinkler heads, maintain a uniform distribution of the water, and prevent over-pressurizing the system. - Manually repaired and assembled sprinkler heads, flow control valves, in-ground moisture sensors, sprinkler solenoids, damaged wires and sprinkler manual control valves.

Bachelors of Mechanical Engineering and Minor in Applied Mathematics.
