PROJECTS

PhisherMan — A Real-time Email Phishing Detection Add-on — Demo

Phiserman is an AI-powered email phishing detection system that boasts sub-150ms latency. To achieve this performance, I fine-tuned a lightweight model and leveraged Rust for development. Additionally, I designed and built a Local Cloud for AI inference during the testing phase, which is documented here.
