Next.js, Laravel API, MySQL, Flutter, Paystack
ElitePay gives everyday users a single wallet to fund, pay bills, and move money without juggling five different apps. We built the web platform and companion mobile app end to end, from ledger design to the Paystack integration that settles it all.
The client needed a transaction ledger that would stay consistent under concurrent load, real-time balance updates across web and mobile, and a compliance-friendly audit trail — all on a timeline of twelve weeks.
We designed an event-sourced ledger in Laravel with idempotent transaction handlers, paired it with a Next.js dashboard for real-time balance and transaction views, and shipped a Flutter companion app sharing the same API contract.

Designed an event-sourced ledger to keep balances consistent under concurrent writes.
Build
Parallel-tracked the Laravel API, Next.js dashboard, and Flutter app against a shared contract.
Hardening
Load-tested payment endpoints and added idempotency keys ahead of the Paystack integration.

Reduced average bill-payment completion time to under 8 seconds
Zero ledger discrepancies reported across the first two audit cycles
“Elite Software Technologies understood the difference between a payments app and a payments system. The ledger has never blinked, even during our biggest traffic days.”
