About

T. L. Roderick writes hands-on books in technology and finance for people who want to learn a field properly, from first principles, and then do real work in it.

The books

• From Zero to Defender is a cybersecurity series that starts with no previous IT experience and builds a home lab, then prepares readers for CompTIA Security+ and beyond. It is defensive by design.
• From Terminal to Production goes from a first terminal command to AI agents running in production. A French edition, Du terminal à la production, is adapted to French and European projects.
• The Python Developer's Handbook, in two volumes, goes from a first line of code to real applications.
• Finance d'entreprise is a complete corporate finance course in French, with a book of 80 worked cases and a formula guide.

Every chapter ends with exercises, labs or worked cases, because a skill is learnt by practising it.
