Backend Engineering with C# & .NET

Build, secure and ship the kind of C#/.NET backends that run banks, insurers and hospitals — and earn a certificate that proves it.

C# and .NET power the core systems of banks, insurers, telcos and government platforms across Africa — and the engineers who can build those systems are consistently among the best-paid backend developers on the continent. This course takes you from a fresh SDK install to an engineer who can design a REST API in ASP.NET Core, model a real business domain in object-oriented C#, query and persist data with Entity Framework Core against SQL Server or PostgreSQL, and reason about async code, LINQ translation and service lifetimes the way senior reviewers do.

This is a practitioner's course, not a syntax tour. You will build a working claims API for an insurer and an appointments system for a hospital group, secure them with JWT authentication, bcrypt password hashing and role- and resource-level authorization, then prove they work with xUnit unit tests and WebApplicationFactory integration tests before packaging everything into a Docker image with health checks and a CI-shaped workflow. Every lesson ends with a concrete practice task on your own machine, and the scenarios — transfer limits, claim lifecycles, settlement reports in naira — are the ones you will meet in a real job.

At the end, a 20-question certification exam spanning the entire course stands between you and your certificate. Score 70% and it is issued automatically — a shareable, verifiable credential that tells employers you can carry a .NET backend from `dotnet new` to a deployed, tested, secured service. Unlimited retakes, no waiting period: when you are ready, it is yours to earn.
