πŸ›  Security engineer. Builder. Professional thing-breaker.


πŸ‘‹ About Me

I'm a Senior Security Engineer who loves digging into code to find the fun, unique, and complicated bugs that others miss. When I'm not breaking things professionally, I'm building tools to make life easier β€” with a strong bias toward privacy and keeping data where it belongs: on your machine.


πŸ”¨ Featured Projects

A collection of browser-based utilities where all processing happens entirely in your browser β€” no data is ever transmitted to any server. Privacy by design, not by promise.

Privacy First No Backend Client Side

A simple HTTP request capture web app written in Rust, inspired by request-baskets. Capture methods, headers, parameters, and body content β€” useful for testing webhooks, debugging SSRF, and more.

Rust Docker Live Demo

A lightweight Rust SMTP server that forwards incoming emails to any HTTP webhook as JSON. Bridges legacy email-only notifications (monitoring tools, alerting systems) to modern services like Discord, Slack, or custom endpoints.
