I teach in the classroom and build outside it.

I teach information technologies at a vocational high school. For two decades I have taught network systems, web programming and robotics coding — and I write here about what I learn.

Educator

I am a Cisco Networking Academy instructor. I prepare students for CCNA and cybersecurity certifications and coach robotics competition teams.

Developer

I build web software — from PHP and Python to Next.js and React. I keep building what I teach.

Engineer

I hold a computer engineering degree. I work on physical network installation, server administration and systems design.
