Skills that matter most: REST API design and consumption, webhook handling and HMAC validation, SQL and database design, Node.js or Python backend, mobile money APIs (M-Pesa Daraja, MTN MoMo), and knowledge of local regulations (CBN, CBK, BoG). Useful certifications: AWS Solutions Architect Associate (infrastructure credibility), Google Associate Cloud Engineer, and PCI DSS Implementer awareness. No specific fintech certification is required by most African employers.
| Skill | Why It Matters | How to Prove It |
|---|---|---|
| Webhook handling + HMAC validation | Core payment event processing | Portfolio project with tests |
| Idempotency patterns | Prevents double fulfillment | Explain in interviews; show in code |
| SQL / database design | Payment records require reliable storage | DB schema in portfolio projects |
| REST API design | Payment services are API-first | OpenAPI spec in portfolio |
| M-Pesa Daraja API | East Africa dominant payment | STK push project on GitHub |
| Security basics (OWASP, input validation) | Payment systems are high-value targets | Security section in READMEs |
| CBK/CBN regulations awareness | Avoids compliance mistakes for clients | Know what licenses, data laws apply |
Skip: most "blockchain for payments" or "DeFi developer" certifications have limited relevance for African B2B payment engineering roles as of 2026.
