Raghav Aggarwal
MS Data Science — Stevens Institute of Technology — graduating May 2026
I build ML systems that go to production, not notebooks that collect dust.
Currently: Claude Code, Agent Orchestration, RAG pipelines, LLM agents, trying to keep up with the latest tech...

What I've Built

Problem Result Stack
Insurance Policy Q&A Agent Insurance docs are dense — people can't find answers fast Two-tier RAG: local vector search for fast answers, auto-escalation to Gemini for complex cross-section analysis. safety guardrails catch sensitive topics before LLM responds LangChain ChromaDB Ollama/Mistral Gemini Streamlit
Lumbar Spine MRI Classification Radiologists manually review hundreds of MRI slices per patient — slow, subjective Benchmarked 5 architectures. EfficientNet-B3: 75% accuracy, 57% severe-class recall (2× next best) with fewest params among transfer models PyTorch timm albumentations pydicom DICOM→2.5D
Exam Score Predictor (MLOps) Demonstrate full ML lifecycle, not just a notebook EDA → 8 models → Ridge (R²=0.88) → Flask API → Docker → GitHub Actions CI/CD → deployed on AWS EC2 via ECR scikit-learn Flask Docker GitHub Actions AWS
Time Series Forecasting Compare SARIMA vs automated methods on real data, analyze COVID recovery asymmetry Box-Jenkins models beat automated ETS on both datasets. financial markets recovered from COVID in ~6mo, consumer behavior took ~24mo R forecast Shiny plotlylive dashboard
