Sentiment Analysis
As Lead Software Engineer, I designed and built Exechon, a modular, layered analytics platform that transforms raw SEC 13F filings, stock financial data, and real-time news into insight-ready datasets. I developed a Rich-based CLI with interactive visualizations for exploring what-if scenarios, stress-testing strategies, and benchmarking performance. The system features a clean architecture with a smart storage layer and extensible design, enabling scalable, data-driven investment research and advanced portfolio simulations.

Mixed Reality
My main responsibility was contributing to the development of the Symaware digital twinning platform in collaboration with Siemens. Using PreScan, Simulink, and ROS, we created a modular architecture that allowed researchers to swap controllers and benchmark autonomy stacks in mixed-reality loops for autonomous vehicles. I integrated realistic sensor models, developed ROS nodes for time-synchronized data flow, and designed demonstration scenarios.
Beyond technical contributions, I wrote detailed documentation, prepared tutorials, and supported other students with lab projects and debugging. I worked with embedded systems such as Jetson hardware, lab equipment (VICON motion capture, depth cameras, lidars), and assisted in various demos for guests and external visitors.

Semantic Segmentation
Undertook a project at SenseLab to develop a deep learning model for garbage detection. Utilized an R-CNN model emphasizing semantic segmentation of litter across numerous categories using low-altitude UAV aerial imagery. Trained the model with the TACO dataset and conducted evaluations to identify various waste types in multiple environments from UAV-acquired images.
Demo Example: Semantic segmentation of an aerosol can with 91.8% accuracy.
