Pro Tips
- *Export AI usage logs alongside Git data so you can correlate tokens, suggestion acceptance, and lead time without manual tagging.
- *Standardize prompt patterns for common tasks, then benchmark cycle time before and after to quantify portfolio uplift.
- *Keep PRs small and label AI-generated sections, which shortens reviews and builds trust in your portfolio screenshots and graphs.
- *Annotate every metric with a user-facing outcome, such as reduced support tickets or faster trial-to-activation, not only throughput.
- *Automate weekly snapshots of dashboards so your public profile always reflects fresh, verifiable progress without manual effort.
