About

I am a recent Mechanical Engineering graduate from Rowan University with a strong passion for problem-solving, hands-on innovation, and computer-aided design. I currently work as a Mechatronics and Robotics Technician II with JLL and Amazon at Amazon fulfillment center LGA9, where I support advanced automation systems in a high-speed fulfillment center as part of the Reliability and Maintenance Engineering (RME) team. Through my academic and internship experience, I’ve developed a strong foundation in mechanical design, robotics, additive manufacturing, and coding languages. I’m skilled in tools like SolidWorks, MATLAB, Simulink, Arduino, C++, and Revit, and have contributed to real-world projects in HVAC design and water treatment asset management. I thrive in environments that challenge me to think critically, work collaboratively, and continuously improve. My goal is to keep growing in the field of automation, robotics, and mechatronics.
