Experience Highlights

Software Engineer and Researcher
Nov 2025 - Ongoing4 months
Project Overview

Exploring a novel approach to representing and analyzing complex operational scenarios by encoding them as structured graph models, enabling advanced simulation, anomaly detection, and decision support.

Designed for defense environments, the system transforms dynamic, multi agent systems into graph representations that can be indexed, embedded, and compared over time, allowing for the identification of deviations from nominal behavior and the evaluation of alternative outcomes.

It is still very much in a research and development phase.

Jan 2025 - Ongoing1 year 2 months
Project Overview

The Scenario Exploration Tool (SET) is a project management platform that lets organizations model, compare, and optimize complex ongoing contracts/programs.

Designed primarily for defense, government, and operation intensive teams, the main goal of SET is to replace static planning tools (spreadsheets) with a dynamic system where users can "branch" active projects into multiple scenarios, adjust variables such as cost, schedule, and resources, and evaluate outcomes.

This introduces a version-control sort of system to project management, allowing teams to safely explore "what if" scenarios to optimize and choose the best path forward.
