Femi Shotola Ishefun Road, Maryland, Lagos | https://github.com/fmshot2 | www.linkedin.com/in/femi-shotola | https://medium.com/@femishotolaa Profile I am a Fin-Tech oriented full-stack developer with close to 9 years experience working with Wordpress, Laravel, React, Vue Js, Node Js and Angular. I have led teams to build popular applications currently used by millions of users. Most Recent Difficult Task I recently designed and implemented the full payment flow and reconciliation system for Google Play and Apple In-App Purchase APIs. The challenge was that in-app purchases don’t behave like standard card transactions – payments can be delayed, subscriptions renew asynchronously, refunds or chargebacks can come later, and each store provides its own APIs and webhooks. Our goal was to ensure a seamless user experience while maintaining financial accuracy and compliance." Solution / What I Designed ● Payment Flow: ○ Integrated both Google Play Billing and Apple IAP APIs. ○ Implemented secure server-side verification of purchase tokens/receipts to prevent fraud. ○ Designed a unified abstraction layer so the client app talks to a single backend API, while the backend routes to the correct store (Apple/Google). ○ Added support for handling SCA-like events (subscription trials, renewals, payment failures, grace periods) which mimic some aspects of 3DS/SCA logic. ● Reconciliation System: ○ Built a ledger-based system that records every transaction event (purchase, renewal, refund, cancellation). ○ Scheduled daily reconciliation jobs that fetch the authoritative transaction history from Apple and Google APIs and compare it with our internal ledger. ○ Implemented dispute handling by syncing refund/chargeback signals and mapping them back to internal users and subscriptions. ○ Designed an idempotent flow so retries or duplicate webhooks don’t cause inconsistencies. Result / Impact ● Achieved 100% accuracy in subscription state across client and backend. ● Reduced payment-related support tickets significantly (users always saw the correct subscription state). ● Enabled financial reporting & audits by exporting a clean ledger of reconciled transactions. ● Made the system extensible so future payment providers (e.g., Stripe, PayPal) could plug into the same abstraction layer.
