1. Redesigned the onboarding experience, using animation we have increased vehicle addition from 10% → 48%, unlocking personalization for 4.8× more users with 0% bounce rate. Which helps us in targeting relevant users and optimising our messaging strategy by shifting from ₹0.80 promotional to ₹0.15 utility campaigns, cutting costs by 81% and boosting WhatsApp CTR from 6–7% → 19%, driving 3× more challan payments. 2. Designed the Park+ Money and Car Loan campaign, introducing new ingresses, urgency cues : Car Loan Carnival: Grew leads from 50 → 1,800, achieved 26 disbursals, and increased loan disbursal from ₹10L → ₹1.6Cr (₹15L revenue). Money Utsav: Doubled daily leads (42 → 96) with the same DAU. 3. Designed the FASTag retention and cross-sell flow, using a contextual “wrong toll deduction” hook to lift CTR from 1.5% → 16% and convert 6–7% of users while reducing reacquisition cost by ~₹90 per user. 4. Revamped the unified order confirmation journey across FASTag, challan, insurance, and other products. Redesigned the experience to educate users about Park+ Petrol, reduced payment confirmation animation time from 6 → 2 seconds, and introduced ad properties that opened a new revenue stream and pushed cross-sell across categories. 5. New flows & usability: launched PDI (Pre-Delivery Inspection) and Review Flow revamp; delivered motion design, micro-interactions, and strategic banners that lifted DAU and in-app engagement. 6.
