Featured Projects

InsiderGuard AI - Insider Threat Detection

InsiderGuard AI is a production-oriented insider threat detection system serving multi-user analyst workflows via a Streamlit dashboard with Firebase authentication. It leverages User and Entity Behavioral Analytics (UEBA) through a hybrid anomaly detection pipeline (Autoencoder + Isolation Forest) to score and flag behavioral risk in real time across 125,000+ telemetry logs, supporting real-time inference on live behavioral telemetry streams and surfacing results as prioritized alerts.

WC 2026 Simulator - XGBoost Match Predictor & Simulator

This project pairs an XGBoost match predictor, tuned via Optuna hyperparameter optimization, with a 10,000-run Monte Carlo bracket simulator generating win probabilities for all 48 World Cup 2026 teams. The backend is a FastAPI REST API with Pydantic v2 schema validation, containerized in Docker and deployed to Render with a GitHub Actions nightly retraining pipeline, with live tournament odds and match probabilities surfaced through a public Streamlit dashboard.

Malicious QR Code Detection

This project fine-tunes a Vision Transformer to classify QR codes as legitimate or malicious, addressing the growing security risks posed by visually indistinguishable phishing codes. Beyond detection, the model's predictions are made interpretable through attention rollout, highlighting the global visual patterns the transformer relies on when identifying malicious intent. Overall, the work demonstrates the feasibility of image-only QR code security as a proactive defense against QR-based attacks.

Multilabel 12-Lead ECG Classification

This project focuses on detection of cardiovascular diseases from 12-lead ECG signals using a custom deep learning CNN tailored to capture cross-lead cardiac patterns. Beyond classification, the learned feature space is explored using a probing classifier to evaluate how well metadata (age, sex, etc.) is encoded in the model's representations. The work aims to enhance automated cardiovascular disease detection and support more reliable decision-making in healthcare settings.

Swoop Advisor - Hackathon RAG LLM

This project leverages the power of Langchain, Ollama, and Chroma to create a document-based question answering system. It uses a vector database to store document chunks and retrieves relevant information based on user queries. The system is capable of ingesting CSV files, splitting them into manageable chunks, and embedding them into a vector space for efficient search and retrieval. The assistant, acting as a college advisor, answers questions by leveraging the stored data.
