Andrew Baker

Group Chief Information Officer, Capitec Bank — Cape Town, South Africa. 20+ years in technology leadership across financial services.

I write about AI engineering, banking technology, cloud architecture, cybersecurity and engineering leadership at andrewbaker.ninja — and the code behind most of those posts ends up here.

Everything below is production tooling I actually run, not demos.
