Mobile Banking App
A full-stack digital banking platform serving 200,000+ users across Pakistan and UAE.
The Challenge
The client's legacy core banking stack couldn't keep up with mobile-first customer expectations. Account onboarding took days, fraud was caught after the fact, and the existing app's NPS sat at -12. They needed a complete reset — without disrupting compliance or the millions of existing accounts.
Our Approach
- 1
Architected a parallel modern stack alongside the legacy core, with an event bus bridging the two so we could ship value incrementally without a big-bang cutover.
- 2
Designed an AI fraud-detection pipeline that scores every transaction in under 80ms — replacing batch nightly review with real-time blocks and challenges.
- 3
Shipped biometric auth, multi-currency wallets, and instant P2P transfers as the first three customer-visible launches over six weeks.
- 4
Set up observability from day one — Datadog, Sentry, and structured business KPIs — so the team could spot regressions in product metrics, not just infrastructure.
What we shipped
The core features that moved the needle.
Biometric Authentication
FaceID and fingerprint login backed by device-bound keys and a secure enclave fallback.
Multi-Currency Wallets
Customers hold PKR, AED, USD and EUR in a single account with real-time FX at interbank rates.
AI Fraud Detection
Per-transaction risk scoring trained on 18 months of historical patterns — sub-80ms decisioning.
Instant P2P Transfers
Send money to any IBAN or phone number in under three seconds, with full audit trail.
