✓ Designed and shipped AI Video (text/photo → video) - Dora's flagship generative feature, taking a still-image app into motion. ✓ Led a presets-over-prompts flow that got first-timers to a shareable clip in under a minute. ✓ Designed the full generation lifecycle (queue → progress → ready → failure) so a minutes-long render never felt broken. ✓ Built a fair credit economy — cost shown before commit. ✓ Placed the paywall at the payoff (right after the first "wow"), not the friction.
