Things I've Built

4thwall
May 2026

Hybrid WAF pairing ModSecurity rules with a fine-tuned DistilBERT model, achieving 94.2% detection accuracy and 0.928 F1 on a custom HTTP traffic dataset. Deployed as a 4-container Docker Compose stack with a real-time React monitoring dashboard processing traffic through a two-layer defense (rule-based + ML), logging every decision, and visualizing attack patterns with 1-second refresh intervals.

WAF Homelab
Jan 2026

Multi-tier web security lab using a reverse proxy WAF protecting a vulnerable backend. Configured HTTPS with self-signed TLS certs and routed 100% of traffic through the WAF layer inside an isolated VMware virtual network.
