🚀 Featured projects

🛡️ AI Firewall — LLM-powered IDS/IPS

Python · LLMs · Docker · Embeddings · REST APIs · Cybersecurity AI

Production-grade autonomous intrusion detection & prevention system exposed via REST APIs. Combines dense vector embeddings with keyword search in a hybrid retrieval pipeline for contextual threat intelligence, then hands the result to an LLM for real-time classification. Containerized and deployed with Docker.

AI Firewall — animated pipeline: traffic to feature extraction to hybrid retrieval to LLM classifier to block/allow
