What we make

We build the infrastructure our teaching runs on.

Plenty of organisations run coding programmes. Very few in the region build the platform underneath.

Platform

In production across our own courses. Available to partner institutions.

Poseidon

A grading platform for code and scanned documents, built and run by us.

Autograding across languages via containerised test runners, PDF annotation, rubric based marking, regrade workflows, multi institution tenancy, and exports. It is what marks the work on every course on this site.

Client work

Emzini Studio

Real client work, delivered by our students and Residents under real deadlines. Most projects are paid, which funds teaching. A small number each year are donated against published criteria.

01 Oneness Pentecostal Church Ministries Website for a denomination founded in Bulawayo in 1975, with assemblies across five countries. Built and running on Emzini weCode infrastructure.

The Studio is a practicum with real stakes, not a free web shop. Selection criteria and annual capacity are set each year and shared with anyone who enquires.

Brief the Studio

Residents

A small paid cohort, building the thing itself.

Three to four people for six to eight months, embedded in the organisation. Everything on this page was built by one of them.

Where residents go afterwards matters as much as what they build here. If you were one and your entry is out of date, tell us.

Credentials

Verifiable, and private by default

Every certificate carries a unique ID and a QR code. Anyone can confirm a credential is genuine without us publishing the holder's name. IDs are random rather than sequential, so the set cannot be enumerated.

Poseidon in numbers

It marks every course we run

Autograding, PDF annotation, rubric marking and regrades, across every cohort and every partner club.
