Fully local, privacy-preserving dashcam incident analyzer using a 5-phase CV pipeline: YOLO11 object detection, SORT tracking, Farneback optical flow, and VLM-powered structured JSON incident narration — all running locally via Ollama. Generates detailed insurance-ready incident reports with vehicle trajectories, collision timestamps, and severity assessments without sending any data to the cloud.

Decentralized DApp on Ethereum (Sepolia Testnet) combating document forgery. Uses IPFS for storage via Pinata, keccak256 hashing on-chain, role-based access control (Admin/Exporter/Public), and MetaMask Web3 integration for tamper-proof authentication. Features a React dashboard where admins can issue, verify, and revoke documents with full blockchain audit trails.

Explainable hate-analysis framework using classical NLP (no transformers). A 7-stage pipeline supports English, Hindi, Marathi, Bhojpuri, and Marwari — implementing tokenization, POS tagging, NER, N-grams, Naive Bayes classification, and speech-to-text. Each prediction comes with a transparent breakdown showing which words triggered the classification and why, making it fully interpretable for content moderation use cases.

WebRTC-based real-time video calling platform with a custom Socket.IO signaling server. Achieves sub-second connection latency in local testing, supporting stable peer-to-peer video calls for 5–10 concurrent users. Features screen sharing, mute/unmute controls, dynamic room creation, and a responsive UI built with React.
