I'm a third-year Computer Engineering student at Ganpat University (UVPCE), specialized in AI/ML. I don't stop at calling APIs — I build the machinery: hybrid retrieval with BM25 + dense vectors fused via RRF, cross-encoder reranking, RAGAS evaluation loops, CNNs with Grad-CAM interpretability, and value iteration written from the Bellman equation up.

I've contributed to HandsOnLLM — the companion repo to O'Reilly's Hands-On Large Language Models — and completed the Stanford / DeepLearning.AI ML Specialization, implementing every algorithm from scratch in Python.

Currently hunting for a Summer 2026 internship where I can point all of this at real-world problems.

Multi-Document RAG Pipeline

End-to-end RAG with citation tracking across documents. Hybrid retrieval — ChromaDB/FAISS dense + BM25 sparse, fused via Reciprocal Rank Fusion — then FlashRank cross-encoder reranking before generation. PyMuPDF ingestion with adaptive chunking; evaluated on RAGAS (faithfulness, relevancy, context precision/recall).

MEd X — Pneumonia Detection

Deep-learning classifier for chest X-rays using DenseNet121 transfer learning on the NIH dataset. Data augmentation to fight class imbalance, plus Grad-CAM activation maps so a clinician can see exactly where the model is looking — interpretability first.

Fake News Detection System

NLP classifier that separates real headlines from fake ones using a BiLSTM + BERT hybrid architecture. Text preprocessing and embedding pipeline feeding a bidirectional LSTM on top of BERT representations, served via a FastAPI inference endpoint.
