Four high-impact projects that highlight LLM systems, cyber-physical security, and computer vision research.

AI Expense Tracker with RAG-Enhanced Financial Reasoning

FastAPISQLiteNext.jsLLMsRAG
  • Problem: Financial queries need trustworthy, non-hallucinated answers grounded in real data.
  • Built: Full-stack system converting natural language -> SQL -> retrieved context -> grounded explanations.
  • Built: RAG pipeline where all numerical values are strictly fetched from SQLite (LLM used only for reasoning).
  • Built: Provider-swappable LLM architecture (Ollama local, OpenAI, Groq, HuggingFace, vLLM).
  • Built: CRUD APIs, analytics SQL, budget vs actual analysis, anomaly detection, plus schema/index tuning.

DER Cyberattack Detection Platform

PythonOpenDSSPyTorchTime-Series ML
  • Built: End-to-end DER simulations combining electrical telemetry and cyber events.
  • Built: Modeled false data injection, spoofing, and command manipulation attacks.
  • Built: Generated ML-ready labeled datasets for anomaly and intrusion detection.

Tiny LLM for Anomaly Pattern Learning

LLMsTransformersPrompt Engineering
  • Built: Evaluated lightweight open-source LLMs to learn normal vs anomalous telemetry patterns.
  • Built: Prompt-based classification optimized for low-latency inference and rapid triage.

Forest Fire Severity Detection (IEEE Xplore)

PyTorchOpenCVComputer Vision
  • Built: End-to-end computer vision pipeline using PyTorch and OpenCV.
  • Built: Applied preprocessing, augmentation, training, and evaluation.
