Financial Technology (Fintech)
Fintech applies software and digital infrastructure to payments, savings, lending, insurance, financial operations and access to financial services.
Tools and technologies
- REST APIs and webhooks
- Mobile-money and bank APIs where available
- Payment gateways
- Python / JavaScript
- PostgreSQL
- Encryption and identity verification services
- Sandbox test environments
Practical examples
- A checkout flow that offers a locally supported mobile-money payment method.
- A small-business cash-flow dashboard that categorises income and expenses.
- A payment reconciliation tool that matches provider references to orders.
Application areas
- Digital payments
- Merchant tools
- Remittances
- Personal and business finance
- Insurtech
- Financial inclusion
Suggested hands-on project
Mini project: build a sandbox checkout with order creation, payment-pending, success and failure states. Verify payment status server-side using the provider’s documented callback or API; never trust a browser redirect alone.
A typical workflow
Map the customer and money flow → choose a licensed provider → design secure payment states → integrate sandbox APIs → reconcile transactions → test refunds and failures → launch only after compliance review.
How to get started
Choose one small, measurable problem, build a prototype with sample data, document assumptions, test common failure cases, and collect feedback before expanding it.
Responsible use: Financial services can be regulated. Use licensed providers, follow applicable AML/KYC and privacy rules, protect payment credentials, and never store card security codes or expose secret API keys.
