Things I've Built

Argus

SOC investigation agent built on Splunk. Automates alert triage, correlates events across data sources, and surfaces actionable findings — cutting the manual work out of incident response.

Recon

Rust-powered CLI network scanner with a terminal UI built on ratatui. Captures live packet data, filters by protocol, and lets you drill into traffic without leaving the terminal.

Records

Full-stack ledger and price management system for business inventory tracking. Handles product records, pricing updates, and transaction history with a TypeScript backend.
