Ages and levels: not declared yet — the tutor adds them in the Faculty Studio.
Drafted from your text by a small rule set in the build (no AI, nothing sent anywhere): a teaching profile focused on how you work with juniors: style, levels and languages. Every contributed problem will carry your name and country, on both euler.swiss and stella.academy, permanently.

Accepted Euler problems per level: a teacher who has written many Euler problems knows what the Euler asks.
Parent-facing view. Child-facing views never carry social handles or off-platform links. All messages, booking and payment stay on STELLA; tutoring sessions with juniors are recorded for safety and begin with an on-camera check-in.
Dr Jonker’s calendar
Dr Jonker publishes availability in Europe/Zurich; it converts to your zone automatically and stays correct across daylight-saving changes. Minimum notice 12 h.
No published slot in the next weeks. The tutor ticks slots in the Faculty Studio; they appear here the moment they exist.
Showcase: streams and view-only pages
Uploads (clips that stream on STELLA only, PDFs in the view-only reader) arrive with the production build. Coming.
