I build systems that find what's broken before someone else does. From security tooling to fraud detection — no shortcuts, just code that holds up under pressure.

The combination of security research, backend engineering, and applied AI puts me in a fairly specific place: I don't just build features, I build things designed to be attacked and hold their ground.

AI Security Engineer

AI-Powered Code Vulnerability Scanner

A full-stack security analysis tool that runs a locally-hosted LLM (Ollama) against a RAG pipeline built on CWE and OWASP knowledge bases, detecting and explaining vulnerabilities in uploaded source code. The RAG pipeline grounds vulnerability explanations in retrieved CWE/OWASP reference material, improving accuracy over raw LLM output. Semantic retrieval is handled with FAISS; findings are returned as structured JSON and rendered into a downloadable PDF report, with async file uploads and CORS configured in FastAPI to support scanning of multi-file codebases.

Diabetic Retinopathy Detection

AI-Powered Severity Classification from Retinal Fundus Images

An AI-powered detection system using convolutional neural networks and TensorFlow to classify retinal fundus images by disease severity. Image preprocessing and data augmentation improve classification accuracy, while transfer learning adapts pretrained CNN architectures to the fundus imaging task. The system is designed to prioritize high-risk cases for rapid clinical review, reducing ophthalmologist workload, with performance evaluated across severity classes to minimize misclassification of high-risk cases.
