I build things that think. After 3+ years shipping production-grade engineering at Optum, I pivoted hard into AI/ML — building RAG pipelines, training classifiers, and obsessing over LLMs. If a problem can be solved with data and a model, I'm already thinking about it.
// 01 — Where I've Been
Real-world engineering that ships, scales, and saves production — before I even got to ML.

Portfolio AI Chatbot
RAG-powered chatbot that answers questions about my portfolio using semantic search. Built with FastAPI, LangChain, FAISS, and OpenAI embeddings to retrieve context from resume PDFs and structured profile data. Designed for production deployment with efficient startup and reliable retrieval.

Email Auto-Classifier & Labeler
A layered FastAPI microservice that connects to Gmail over OAuth 2.0 and auto-labels inbox mail into a fixed six-class taxonomy. Fine-tuned a local DistilBERT classifier via knowledge distillation — using GPT-4o-mini as a teacher to bootstrap the dataset — running fully on-device so email content never leaves the machine. Lifted macro-F1 from 0.67 to 0.95 with inverse-frequency class weights.

RAG Document Chatbot
Answers questions over any PDF — with sources. Built a modular pipeline using LangChain, MiniLM embeddings, and a FAISS vector store. Prompt guardrails via TinyLlama. MMR deduplication for retrieval quality. Persistent index, CLI interface, production-minded from day one.

Email Spam Classifier
End-to-end spam filter: TF-IDF n-grams + Logistic Regression with class balancing. Beats Naive Bayes baseline through thoughtful feature engineering and regex preprocessing. Served in real-time via a Flask API — not just a notebook, an actual product.
