• Identified and resolved GPS Block IIR simulation deadlocks and initialization failures. Fixed intermittent rendezvous deadlocks by simplifying state logic. Made the logging mechanism thread safe by employing a.
• Fixed GPS Block IIR simulation M-code generation and timing. Corrected a reversed tail-biting convolution code. Ensured proper time alignment and buffering between independent epoch-based generation and second-based.
• Refactored and enhanced a GPS Block IIR upload interpreter. Rewrote Python tool to handle page-spanning control elements. Added validity checks for parity, checksum, block length, and header fields.
• Analyzed command plans, telemetry, and space vehicle logs to resolve defect reports. Modified test procedures for correctness. Updated the GPS Block IIR and IIF simulations to fix modeling deficiencies.

• Lead high performance computing (HPC) engineer for the AIM-120D AMRAAM simulation. Tracked and forecast computing resource needs. Proposed, deployed, and verified over $2 million in new hardware. Considered model of.
• Optimization expert for the AIM-120D AMRAAM simulation. Rearchitected algorithms and data structures, remedied hotspots, and vectorized instructions. Data-driven effort using profiling, static analysis, vectorization.
• Designed and implemented a continuous integration framework for the AIM-120D AMRAAM simulation. Created an automated tool to reconfigure, build, execute, compare, track, and notify. Monitored system performance.
• Principle debugger for the AIM-120D AMRAAM simulation. Improved signal handling and exception reporting. Handled the most nefarious repeatability issues, floating point exceptions, and segmentation violations.
• Modeled processing chain latencies and delays for the NLOS-LS simulation. Ensured simulated processing chain matched real-time system by reordering models, delaying data, and switching to a push-driven paradigm..
• Rearchitected the NLOS-LS simulation. Enabled parallelization, enhanced stability, and simplified the C++ simulation by creating a monolithic simulation from multiple IPC-driven processes.

Laurel, MD

• Technical direction and analysis of the FBX-T radar, a component of the Ballistic Missile Defense System. Scrutinized the nuclear threat space, studied special topics, and oversaw Raytheon’s implementation in.
• Conducted independent verification and validation for the Comet Nucleus Tour, a NASA Discovery mission. Derived algorithms from requirements and wrote scripts to confirm correctness.
• Resolved Ship Self-Defense System trouble reports for the U.S. Navy. Mitigated plan position indicator visualization issues by using a pseudo-video technique and updating the graphical user interface. Solved a closest.
• Researched and developed methods of fractal-based image discrimination. Performed a literature survey, implemented promising algorithms, and tested techniques on synthetic aperture radar images.
