Defining and developing front-end and back-end interactions in Typescript and Java.

Collaborated with the cloud team to design and implement a solution for distributing configuration and calibration data to new vehicles when they boot, instead of embedding the data in each software build. This saved hours of turnaround time when bringing up new vehicles and iterating on sensor calibration data.Developed an asynchronous Python server to host HTTP request endpoints that allowed clients to retrieve vehicle information and reprogram vehicles. This server also used websocket connections to return state information to multiple client dashboards.Discovered unused drives on several boards running perception software and wrote a script to re-partition the boards to make use of the new drive space while ensuring read-only access to critical data.Created a number of C++ and Python ROS nodes for pulling data from a GraphQL gateway and transforming the data into ROS parameters and messages.

Architected, designed, and developed the core logic for a C++ library that allowed customers to build applications to use product functionality more easily.Developed prioritization logic for applications to make use of a distributed system of base station receivers with various hardware limitations.Designed, implemented, and optimized complex SQL queries for mission-critical processes.Created a common and simplified C++ interface to hide the details of a more complex pub/sub messaging backbone to promote quick, clean, and robust development.Built a socket-based Python-to-C++ API using Google Protobufs to serialize messages.Regularly mentored junior engineers in state machine operation, multi-threaded programming, and system-level thinking.Engaged with customers and partner companies at various locations to debug and deploy new, cooperative hardware and software solutions in sometimes time-sensitive scenarios.Facilitated Agile planning and execution for a cross-disciplinary team supporting multiple projects and customers.

Worked with a six-person team to develop applications that made use of cellular communications technology. This company was purchased by CACI.

Managed a four-person software development team in the design and implementation of a flexible serial interface used to test a real-time hardware-in-the-loop simulation.Developed a real-time geolocation program by translating MATLAB source code into multi-threaded C++ and re-implementing algorithms on a GPU using CUDA.Acted as an air defense artillery simulation subject matter expert for two years and trained others in the use of the gun models.Regularly briefed sponsors on the programmatic implications of modeling and simulation analysis.Coordinated with intelligence agencies to examine and test new survivability models, communicating errors and fixes as appropriate.
