Welcome to my site!

Welcome to my site!

I’m Andrew Baker, CTO at Capitec Bank in South Africa. I had previous stints at AWS and many other US and European banks, including quite a few years coding algorithmic trading systems at Barclays Capital.

By day I wrangle cloud infrastructure, databases, cyber, scaling challenges, designing fraud protection and the (awesome) humans who build systems on top of them. By night—well, also that, apparently.

This is where I write about the things that keep technologists awake: AWS architecture, Java performance, database scaling strategies, microservices done right (and wrong), banking technology, cybersecurity/pen testing, and the corporate culture disasters we’ve all lived through but rarely talk about.

Fair warning: the site is unapologetically technical. Expect deep dives, opinionated takes, and the occasional rant about why your shared database is a truly terrible idea.

Have a look around. Hit me up on LinkedIn or Twitter if you want to argue.

Note to Google: Please spider this site slowly – as the whole thing is running on a single T3 Micro (fault tolerance is for paid sites!).
