About Me
With over thirteen years of professional experience, I have honed my skills in analytical and experimental research and development, systems engineering, technical project management (~$5M/yr), and people management. Throughout my career, I have consistently delivered results through a combination of innovation, strategic thinking, and effective leadership. A key aspect of my experience lies in my ability to communicate complex ideas effectively. Whether it's presenting to customers, engaging with external stakeholders, or interacting with colleagues at all levels of management, I excel in conveying technical concepts in a clear and accessible manner. At Lockheed Martin, we share a commitment to innovation, precision, and strategic growth, and I am dedicated to contributing my diverse skill set to advance our industry-leading projects.
