BADJATE.

A real-time CCTV threat detection system built end to end — masked-individual detection, 6-class weapon recognition, and zone-based monitoring that fires a WhatsApp alert with image and GPS evidence the moment something looks wrong. Shipped as a full YOLOv8 → Flask → browser application, not a notebook demo.

🏅 Gold Medal — AI Innovation Expo 2026 (IBM / CareerTiQ)

A full RAG pipeline that reads a candidate's résumé and generates role-specific technical questions on the fly — semantic chunking, sentence-transformer embeddings, vector search in ChromaDB, and context-grounded generation through Ollama. Question difficulty adapts as the candidate answers, then the system scores and reports performance automatically.

An end-to-end e-commerce data warehouse — customer, order, product, payment and shipping data merged into a Star Schema on Amazon Redshift. SCD Type-2 history, CDC, incremental MERGE loading, full Airflow orchestration, and a FastAPI + React dashboard surfacing revenue and customer-behaviour insights.

A self-contained NLP application — zero paid translation API in the loop. A custom TF-IDF extractive summariser cuts text by an average of 71%, and a three-stage Hinglish detector (Devanagari Unicode + a hand-built lexicon + langdetect) handles code-mixed Indian text that most translators choke on.

A post-training evaluation framework that checks whether an LLM's reasoning actually holds up — logical consistency, completeness, instruction adherence — and surfaces hallucinations even when the final answer happens to be right. Backend-agnostic across Ollama and API-based models.
