Fintech · Ncmc Prepaid Card Platform
Kashware
Full-stack fintech platform.
The brief
Launch a branded NCMC prepaid card product (NeoZap) on the M2P fintech infrastructure with user onboarding, KYC, payment loading, and a gamified rewards experience — then scale to digital gold investment and a full voucher marketplace.
What we built
A comprehensive consumer fintech super-app ecosystem built over 4+ years comprising:
- A Node.js backend platform integrating M2P for NCMC/prepaid card issuance with full KYC, multi-PG payments (Razorpay, Cashfree, Paytm), autopay, and card lifecycle management
- A Flutter mobile app (NeoZap) with onboarding, gamification (coins, challenges, levels, spin wheel), rewards marketplace (Woohoo), digital gold investment (SafeGold/Augmont), chatbot support, NFC, and SOS
- Three Next.js marketing/ecom websites (NeoZap, NeoFinity, NeoVault) with full analytics, A/B testing, and dynamic CMS
- A React/Redux admin panel with ops automation, reward/offer management, and customer support tools
- AWS EKS infrastructure with Jenkins CI/CD, RDS, Redis, and EFK observability. The platform migrated users from legacy Slaypay to NeoZap and expanded into digital gold and a web-based rewards PWA.
