If you're hiring for agent tooling, systems performance, or privacy/security foundations, I'd love to talk.

Good Conversations

  • Debugging and performance regressions in real developer environments
  • Agent tooling: retrieval, patching, deterministic workflows, and guardrails
  • WebGPU/WASM product work for client-side ML
  • Infrastructure: NixOS, DNS, TLS automation, and operational reliability

Response time: I typically respond within 1-2 days.
