About

A practitioner who teaches — not a guru who pretends.

I spend my weeks closing tickets, building labs, and writing field notes. The courses and ebooks here are a distilled version of what actually helps people land their first IT role and grow into security.

IT support that scales

From first ticket to systems thinking — runbooks, escalations, and the language of operations.

Cyber, the practitioner way

The defensive stack: identity, networks, endpoints, and the people who break things.

Career-first teaching

Every lesson maps to a hiring signal: a project, a certification, or a story you can defend.

Five short paths. One real career.
