Constructive chaos, carefully supervised

I design playful learning experiences (and the occasional digital contraption) that make people feel clever.

I’m Mark Calleja (a.k.a. MrC) — a rogue pedagogue and creative technologist. I make projects, pathways, and workshop experiences that turn “I can’t code” into “oh no, I’ve built a game.”

What I do (on purpose)

Learning

Engagement-led learning design

Curriculum, activities, and resources that start with curiosity, add just enough challenge, and end with confidence.

Making

Playful computing & prototyping

Hands-on builds, tiny experiments, and interactive demos that teach concepts without the lecture fumes.

People

Workshops & facilitation

Sessions that feel like a game, stay inclusive, and still land the learning outcomes (yes, really).

Currently

Building Code Club Projects: the sneaky kind of education.

I work with brilliant humans to ship coding projects and learning pathways that are practical, accessible, and unapologetically fun. My special move is making the learning feel like play — without losing the rigour.
