Industries — Fintech & Financial Services
Fintech engineering that handles real money.
Payment gateways, digital wallets, mobile money, and high-volume financial infrastructure — built with the rigour that financial transactions demand. We've rescued failing platforms and built new ones from scratch.
Case Study
Azampay — East African Fintech Platform Rescue
Azampay is an East African fintech platform connecting merchants, mobile wallets, and payment processors across multiple countries. When Innoblocs engaged, the platform was failing — performance issues, data integrity problems, and a codebase that was preventing the team from shipping.
We diagnosed the root causes, stabilised the platform, and systematically addressed the architectural issues that were causing the failures. Azampay became a revenue-generating platform capable of supporting the growth the business needed — processing payments across mobile wallets, bank transfers, and e-commerce channels throughout East Africa.
Fintech Capabilities
Eight capability areas covering the full spectrum of financial technology engineering — from payment gateway architecture to compliance and fraud prevention.
Payment Gateway Development
End-to-end payment gateway architecture: merchant onboarding, transaction routing, settlement processing, refund management, and multi-currency support. We design for idempotency, retry safety, and reconciliation accuracy from the first sprint.
Digital Wallet & Mobile Money
Mobile wallet platforms supporting top-ups, P2P transfers, bill payments, and merchant QR code payments. Balance management, transaction limits, KYC verification flows, and integration with mobile network operator payment rails.
E-Commerce Payment Integration
Payment integration for high-volume e-commerce — checkout flows, cart abandonment recovery, instalment payment schemes, and multi-merchant marketplace payment splitting. Optimised for conversion, not just compliance.
Financial Services APIs
Building and integrating with banking APIs, open banking (PSD2/FAPI), payment provider SDKs, and financial data aggregators. REST and ISO 20022 message formatting for institutional financial services integration.
Fraud & Risk Systems
Transaction anomaly detection, velocity checking, device fingerprinting, and behavioural scoring for fraud prevention. Rules engines and ML-based scoring integrated into the payment authorisation flow without adding latency.
Reconciliation & Reporting
Automated reconciliation between internal transaction records and payment provider settlement files. Discrepancy detection, exception workflows, and financial reporting dashboards for operations and finance teams.
Compliance & Security
PCI-DSS scope management, tokenisation with payment vaults (Stripe, Braintree, custom), end-to-end encryption, and audit logging. We understand where compliance requirements intersect with engineering decisions.
Platform Rescue & Turnaround
If your fintech platform is failing — performance degradation, data inconsistencies, escalating cloud costs, or a team that can't ship — we have a track record of diagnosing the problems and fixing them. Azampay is our proof.
Fintech Reality
Payment systems don't get to be eventually consistent.
In most software, a bug causes an error message or a wrong calculation. In payment software, a bug causes a double charge, a failed settlement, or a balance discrepancy that requires weeks to reconcile. The engineering standards are higher because the consequences of failure are higher.
Idempotency keys on every payment operation — so a network timeout doesn't become a duplicate charge. Reconciliation from day one — so you know within 24 hours if internal records disagree with provider settlements. Immutable audit logs — so every state transition in a payment is traceable.
These aren't features we add if the client asks for them. They're requirements we bring to every fintech engagement because we've seen what happens when they're missing.
Idempotency Everywhere
Every payment operation is idempotent — safely retryable without side effects. Network failures become operational non-events.
Reconciliation First
Reconciliation between internal records and provider statements is designed as a core feature, not a remediation project.
Immutable Audit Trail
Every state change in every transaction is logged with timestamp, actor, and reason. Disputes and investigations are answerable.
Fault Isolation
Payment failure in one channel or merchant doesn't cascade. Circuit breakers, bulkheads, and graceful degradation are architectural requirements.
Load Testing
Payment systems are load-tested at 3–5x expected peak before go-live. Black Friday shouldn't be a stress test.
PCI Scope Awareness
We understand which components are in scope for PCI-DSS and how to use tokenisation and vaulting to minimise that scope.
