+50% transaction success · one checkout
Android payment integration developer
Integrate regional payment gateways into Android without spaghetti checkout code. I own the payment layer on a live white-label platform serving GCC markets — Tap Payments GoSell and Checkout.com Frames behind a single PaymentProvider abstraction, plus Google Pay, tokenised saved cards, wallet balance, gift cards, cash on delivery and BNPL.
Gateways & methods integrated
- Card acquirers — Tap Payments (GoSell SDK), Checkout.com (Frames), Amex, Visa, Mastercard
- Regional wallets — KNET (Kuwait), Benefit (Bahrain), mada (Saudi Arabia), STC Pay, Tami
- BNPL — Tabby
- Platform — Google Pay, Google Play Billing (subscriptions & in-app products)
- In-app tender — wallet balance, gift cards, promo codes, cash on delivery
Architecture principles
- Open/closed — entering a new market means adding a PaymentProvider implementation, not editing checkout UI.
- Tokenised cards — saved payment methods with PCI scope minimised via provider SDKs.
- Failure handling — user-visible retry paths, provider error mapping, analytics on drop-off.
- 3DS & regional flows — tested against live GCC payment rails, not just sandbox happy paths.
Measured outcomes
- +50% transaction success after unifying five gateways behind one checkout at Ozoned Digital.
- Live production volume across COFE white-label brands in Saudi Arabia, UAE and Kuwait.
- Full Play Billing lifecycle on Classmate Playdate — subscriptions, acknowledgement, server sync.
