Developed a modular C++17 Deep Packet Inspection engine for offline PCAP analysis. Implemented Ethernet, IPv4, TCP, and UDP packet parsing, TLS Server Name Indication (SNI) extraction, five-tuple-based flow tracking, configurable packet filtering, and per-flow traffic statistics. The project focuses on protocol-aware network traffic analysis without decrypting packet payloads.

Built a semantic vector database in C++17 implementing HNSW, KD-Tree, and brute-force nearest-neighbour search for similarity retrieval. Developed a REST API and interactive web interface supporting vector insertion, semantic search, algorithm benchmarking, and PCA-based visualization. Integrated Ollama for local embedding generation and implemented a Retrieval-Augmented Generation (RAG) pipeline for document indexing, vector retrieval, and context-aware question answering.
