Mister Wiz Ecosystem
A digital ecosystem for an English school in Brazil — built by the mentor who uses it every week: report cards, teacher dashboard, and a live quiz app.

The problem
Teachers were spending hours turning spreadsheet grades into student reports. The school needed tools that matched how they already taught — not another generic LMS that nobody would open.
The approach
- 01Mapped the real reporting workflow with teachers: CSV in, print-ready report cards out, with per-skill radar charts parents can read at a glance.
- 02Shipped a Flask + PostgreSQL report compiler and teacher dashboard on Railway so staff could run reports without developer help.
- 03Built a gamified quiz app students actually use in class — live on Vercel — so practice and assessment stay in the same ecosystem.
The outcome
- Reporting that used to take an afternoon now runs from a CSV upload to print-ready cards.
- Teachers and students use the tools weekly — the ecosystem is live, not a demo.
- One person owns pedagogy and product, so features ship against real classroom friction.
