The product

Find the environment drift behind works-on-my-machine failures.

A deterministic command identifies runtime, network, Git, service, and certificate differences that commonly delay local environment diagnosis.

01 · Challenge

Environment failures frequently result from runtime mismatches, missing configuration, occupied ports, incorrect branches, certificate errors, or unavailable services.

02 · Approach

I designed deterministic checks, sanitized baselines, machine-to-machine diffs, active probes, structured output, and CI-friendly exit codes without reading secret values.

03 · Outcome

A documented and tested CLI distributed across macOS, Linux, and Windows release targets, with no daemon, cloud dependency, or AI layer.
