High-impact contributions for African fintech: 1) Improve documentation on existing Paystack or Daraja community SDKs (add examples, fix errors). 2) Add tests to payment libraries that lack them. 3) Build and publish a well-documented unofficial Paystack SDK for a language/framework not yet covered. 4) Contribute to WooCommerce Paystack plugin or Medusa Paystack plugin. 5) Publish utility packages: webhook signature validator, African bank code lookup, mobile money number formatter.
| Contribution | Signal | Effort |
|---|---|---|
| Fix errors/add examples to Paystack community SDK docs | Attention to detail, API knowledge | Low |
| Add test suite to an untested payment library | Testing discipline, understanding of edge cases | Medium |
| Build an HMAC webhook validator utility (npm/pip package) | Security knowledge, useful tool | Medium |
| Build Paystack SDK for Go, Rust, or another unserved language | SDK design, deep API knowledge | High |
| Contribute to WooCommerce/Medusa/Saleor Paystack plugin | Platform integration expertise | Medium-High |
| African bank code lookup library (all Paystack-supported banks) | Market knowledge, useful utility | Low-Medium |
Alternatively, start your own utility package. A well-named npm package with a clear README, 100% test coverage, and a real use case is more valuable to your portfolio than 10 minor PRs to other projects.
