Note

I build sharp, single-purpose tools — mostly in Rust and Zig, sometimes in Go or Python. Security scanners, developer utilities, AI infrastructure, and the occasional absurd experiment. On GitHub since 2008. Everything ships.

About

I'm a systems-level software engineer focused on security tooling, developer infrastructure, and AI-native systems. Most of my work lives at the intersection of offensive security, protocol engineering, and CLI design — shipping single-binary tools with minimal dependencies that solve one problem well.

  • Security research — network beacon detection, distributed scanners, web fuzzers, OSINT frameworks, and supply-chain forensics
  • Developer tools — self-hosted tunnel servers, webhook inspectors, deterministic crawlers, and CI/CD automation
  • AI infrastructure — Model Context Protocol (MCP) servers, multi-agent coordination protocols, and DSLs for composable AI systems
  • Systems programming — Rust-first, with production work in Zig, Go, Python, TypeScript, and Nim
  • Open source — 40+ original public tools, all designed to be auditable and forkable

I care about software that is small, correct, and observable. If it can't be deployed with scp and run without a runtime, it's probably too complicated.
