Assisted with a partial database migration effort, converting relational databases to non-relational databases. Assisted with upgrading production Linux and Windows server Operating Systems along with software packages reaching end-of-life. Assisted with the execution of tests dictating cybersecurity requirements for computer systems.

Worked with a small team to develop a color-coded web interface for visualizing crime data in Baltimore City, Maryland. The web interface was hosted on a web server from the university, deployed in a Docker container.

Assisted over 20 students each work week with fundamental programming principles, object-oriented programming, multi-threaded programming, and data structures/algorithms analysis. Offered design/syntax-specific help in Assembly, C, C++, Java, JavaScript, and Python.

Assisted with discovering potential vulnerabilities within wireless vehicular communications. Developed several simulations using frameworks such as the Simulation of Urban Mobility (SUMO), Objective Modular Network Testbed in C++ (OMNeT++), and Vehicles In Network Simulation (VEINS). Evaluated vulnerabilities in current vehicular systems via Controller Area Network (CAN) bus hacking.
