What we plan for in a system that runs in Nigeria.

Nigeria has its own data protection rules, and some sectors add rules on where data may be stored. We settle where data lives, who can reach it and how access is logged at the design stage. We are engineers, not lawyers: your legal advisers confirm what applies, and we build to that. Ledgers: Reconciliation built in, so a payment can be traced from the gateway to the books. Event streams: Billing and usage events processed in order and checked, with replay when something fails. Older systems: Legacy applications moved to the cloud one piece at a time, while customers keep working. Offline-tolerant: Work that carries on when connectivity drops and syncs once it returns.
