iBind KYC
Two enterprise KYC apps, audit-ready from day one.
The brief, in a paragraph.
iBind Systems required two complex KYC authentication applications — CIP and DCID — for enterprise clients in the financial services sector. These apps needed multi-step document verification workflows, strict compliance requirements, bank-grade security, and the ability to handle sensitive personal data reliably. The development needed to achieve high test coverage to meet audit requirements, and the apps had to work flawlessly across a wide range of devices.
Every project has a story before it has a solution. Here's the part nobody writes on the case-study cover.
Compliance, security, and developer velocity — pick three.
Most KYC apps choose two. iBind needed all three. Documents had to be captured, validated, and uploaded under hostile network conditions. Sensitive data needed encryption in transit and at rest. And the audit trail had to be defensible in an external review.
- 01Multi-step document verification across 12+ jurisdictions
- 02Bank-grade security on a mobile target surface
- 03Audit-mandated test coverage thresholds
- 04Variable network reliability across emerging markets
Clean Architecture, BLoC, and tests as a contract.
Architected both applications using Clean Architecture with BLoC pattern, ensuring clear separation of concerns and testability. Built multi-step document verification flows with real-time validation, camera integration for document capture, and OCR processing pipelines. Implemented comprehensive unit and integration testing achieving 85% coverage, meeting enterprise audit standards.
Clean Architecture with BLoC
Separation of presentation, domain, and data layers. Business rules lived in pure Dart, testable without Flutter.
Camera + OCR pipeline
Custom capture UX with real-time edge detection, fallback to manual upload, OCR results pre-validated client-side.
Encrypted local storage
All sensitive intermediate state encrypted with platform keystore. Never persisted document images longer than necessary.
Tests as audit evidence
Every business rule had a unit test. Every flow had an integration test. The audit pack wrote itself.
Two apps. One platform. Audit-ready.
Both apps share an internal SDK of capture, validation, and upload primitives. New jurisdictions plug in as configuration, not code.
- 0185% unit test coverage across both CIP and DCID
- 0297% first-attempt success on document verification
- 03Sub-3-second OCR + upload cycle on mid-range Android
- 04Zero compliance findings in external audit
- 0512+ jurisdictions onboarded as config, not feature work
The numbers, after the dust settled.
Exceeded the 70% audit threshold for financial-grade software.
Document verification flow completed without retry on the first try.
External compliance audit closed with zero remediation items.
New countries and document types ship as configuration.
What changed, measured.
| Metric | Before | After |
|---|---|---|
| Unit test coverage | Below the 70% audit threshold | 85%, satisfying enterprise audit requirements |
| Document verification first-attempt success | Multi-retry capture flow, frequent user drop-off | 97% completed on the first attempt |
| Adding a new jurisdiction | Feature work — per-country code branches | Configuration — 12+ jurisdictions onboarded as config |
| External compliance audit findings | Unaudited | 0 remediation items, audit closed clean |
