About

Engineering breadth with explicit proof boundaries.

I am Patrick Simonetti, working publicly as Patrick Dev and PatrickDev-it. I work as an AI agent, platform, and full-stack engineer. The portfolio is deliberately structured so each project proves a different form of engineering ownership without hiding its limits.

Portfolio architecture

Complementary, not repetitive.

Local systems agent

Review standard

What qualifies as evidence.

  1. Problem: a specific user, constraint, outcome, and deliberate exclusion.
  2. Architecture: boundaries, invariants, trust model, and rejected alternatives.
  3. Correctness: positive, negative, authorization, concurrency, and failure tests.
  4. Operations: reproducible artifact, configuration, observability, migration, and rollback.
  5. Communication: concise reviewer flow, reproducible commands, and explicit limitations.

Professional profile
