Runara project preview

High time you changed your design workflow

The design workflow I built at Runara: a design system that lives in a repo, a Figma file Claude Code can read and write, and a review agent that lets the whole team contribute to the system without waiting on me. What changed since the redline years, what the AI gets wrong, and where I still make every call.

Why onboarding is important in D2C apps

Café Cal's onboarding was the most honest of the four I compared and the only one that converted nobody. How a competitor teardown and the subscription-app research turned 8 questions into a 20-step flow with a plan worth paying for. Today around 10,000 people use the app across iOS and Android.
