THE CHALLENGE
Obsolete technology – Ionic Cordova ceased active support, blocking OS upgrades and security patches.
Single-platform reach – iOS users were completely unserved.
Poor usability – Customers struggled to locate balances, freeze cards, or make third-party transfers.
Code abandonware – No documentation or CI/CD pipeline; hard-coded secrets in the repo.
Versatec needed a total product reset—but without repeating the two-year misadventure that stalled growth.

THE SOLUTION
1 • Discovery & UX Overhaul (Weeks 1-5)
Stakeholder & user interviews uncovered the top pain points and success criteria.
Rapid wireframing in Figma; validated flows for balances, card blocking/unblocking, and peer transfers.
FigJam roadmap workshop prioritized releases: V2 (must-haves) → V2.1 (nice-to-haves) → V3 (innovations).
2 • Lean Cross-Platform Engineering (Weeks 6-24)
Flutter rebuild: one code-base, native look & feel on iOS and Android.
Domain-driven architecture decoupled UI from Versatec’s payment APIs.
Security baked in: Firebase Auth with biometric fallback; secure key store for tokens; MASVS L2 penetration test passed on the first attempt.
CI/CD (GitHub Actions + Fastlane) auto-signed and shipped nightly builds for QA.
3 • Quality & Compliance
800+ automated tests (unit, widget, and end-to-end) keep regressions near zero.
App Store / Play Store hardening checklists integrated into the Definition of Done.
