Use cases

Write-ups of solutions I've built: products, integrations and, more and more, agents inside systems that already exist. Each one covers the problem, the constraints, the architecture, what shipped and what I'd do differently.

In-house at Maul

Things I've built as an engineer at Maul.
  1. Sep 2026Proof over trust — letting an agent verify Maul's admin appWriting the feature map found five real product bugs before any test existed, including an edit form that silently wiped a company's billing discount.Maul · agents

  3. Apr 2026A read-only agent harness over Maul's production MCP serverReplaced a managed-agents prototype with a thin CLI client that discovers the server's 32 tools at startup and filters out the 3 that write, so the model can only read.Maul · agents
