Platform engineer and security tooling builder. I design production infrastructure, build open-source security platforms, and ship engineering tools
Nicholas Ferguson is a platform engineer and security tooling builder whose skills guide an AI agent through disciplined software engineering work, including writing and debugging tests, tracing errors back to their source, validating data across system layers, and verifying work before claiming it is complete. His catalog also covers skill authoring itself and visual design for posters and static artwork in PNG and PDF formats. Much of his work centers on eliminating flaky tests and unreliable verification habits.
