Backend Developer Portfolio Path: Ship 3 Production APIs and Land Your First Contract
Build three genuinely production-grade backend APIs — a secure CRUD service, a payments-and-webhooks integration, and a multi-tenant domain API — deploy and document them, then use that live portfolio to land your first paid contract.

What you'll gain
“Learn ten languages, get a computer-science degree, then apply to hundreds of jobs and hope” is how most people imagine breaking into backend development — and it skips the one thing a first client actually wants: running evidence that you can build a safe, working service. This course teaches the path that works. You do not build bigger apps than a tutorial; you build the same small services to a professional finish — deployed over HTTPS, with real authentication and ownership checks so one user cannot touch another user’s data, validated input, a consistent error shape, a real database with migrations, automated tests, interactive OpenAPI docs, and secrets kept out of your code. You climb a three-API ladder: a CRUD-and-auth service that proves the fundamentals; an integration that consumes a real payment or messaging provider and verifies its webhook signature and processes idempotently (built on sandbox keys — never real money); and a domain API with roles, isolated multi-tenant data, background jobs and reporting. You learn to defend against the actual OWASP API Security Top 10 — starting with BOLA, the number-one risk — to ship each service with Docker and continuous integration and a green test badge, and to package every one so a hiring manager understands it in sixty seconds from a live URL and a hosted Swagger page. Then you face the market honestly: it is real but competitive and portfolio-gated; a Nigerian junior competes in a global pool and wins on proof of work, not certificates; the pay is in dollars but the naira you spend it as is volatile, and platform and payment-rail fees erode the sticker rate — so you learn to think in net take-home, to specialise into a niche your portfolio can prove (a working, documented Paystack or Flutterwave backend is locally distinctive), and to refuse a sober list of job scams whose one tell is simple: money should flow to the worker, never from the worker to get the job. Two developers travel with you: Emeka, self-taught in Lagos, and Aisha, a computer-science graduate in Abuja using a local role as a bridge to remote dollar work. Where a number could not be verified — a live rate, a platform fee, an exchange rate — the course gives an honest range and tells you to confirm it, rather than inventing it.

Frequently asked
Is the certificate verifiable?
Yes. Every certificate carries a unique ID and a cryptographic signature. Anyone — an employer or a client — can confirm it instantly on our public verification page, with no login.
Who teaches this course?
A vetted expert author — Sankofa Skills Studio. Every expert course is reviewed and fact-checked before publication, and the author earns a revenue share on your enrolment.
How long do I have access?
Lifetime. Once you enrol you keep access to the lessons, practice mode and flashcards — including future updates to this course.
What happens if I don't pass the exam first time?
You can retake it — up to 5 attempts, with a 12-hour wait between attempts. Practice mode is unlimited, so rehearse with the same verified question bank until you're ready.
Can my team enrol together?
Yes. Talk to us about group and organisation rates — certifying a whole team is faster and cheaper than one at a time.
