In my capacity as a Mission Assurance Engineer, I served as a Data Analyst on the F-35 DFX Program.I was responsible for developing data analytical software from conception to deployment to monitor and grow production, primarily through the use of push-button data extraction methods written in SQL and VBA (some Javascript, some Python).Additionally, I served in the role of Project Manager as I was selected as a lead for two different large-scale, interdisciplinary and cross-functional technical projects. These responsibilities included assigning actions, driving them to closure, deriving business values, developing business cases, assembling the proper teams to ensure project completion while simultaneously improving quality and reducing cost, and for reporting these efforts at executive level visibility.I was also fortunate enough to develop and implement a data and data science based introductory training for internal engineers.

During my second internship with Northrop Grumman, I became tasked with a variety of assignments. Many included writing large queries to extract and properly input data, helping to design both the logic and implementation of departmental tools to use, render, and output the recently extracted data using various programs created in VBA and some in Java, and the development of new algorithms to apply to supplier effectiveness. Additionally, I helped to increase data visibility efficiency by significantly reducing run time for extraction.Additionally, I performed various cybersecurity operations. I competed in a Cyber Warfare competition, open to the company, placing 2nd overall. Further, I engaged in vigorous penetration testing to evaluate the strength of an undisclosed network's defenses.

While holding a position as a summer intern within the Mission Assurance department of Northrop Grumman Corporation – Electronic Systems (NGES), I was primarily tasked with the repair and rebuilding of a computer program used by numerous functional groups within NGES. It blends various data inputs, and, using a mathematical algorithm, produces a "score"​ for each supplier. As well, the tool can produce an individual report to send to a supplier.My primary function this past summer was to rebuild the tool, which became inoperable over a year ago. In that time frame I was successfully able to identify and correct the problems causing the program to fail, create a number of measures and variants to facilitate the use of this tool, generate over 10 instructional guides to aide both the first time users and experienced users with working the tool, and actually change the data inputs to make them less complicated and more efficient, producing more accurate results. Further, I successfully renovated the tool’s cosmetics making it appear more user friendly, and reducing its run time from a few minutes to a few seconds.As well, I assisted some of NGES' space programs in our warehouse facility, aiding with inspections, acceptances, and receiving items. At some points, I needed to inspect certain components of a radar system by comparing them to the scaled drawing to ensure their compliance both with NGES and our customers.
