Xamina is not a quiz tool with a proctoring add-on. It is seven domains (tenancy, banking, assembly, delivery, integrity, integration and audit) designed together so that the answer to “can you prove that?” is always yes.

Things a role can control
so each job sees only what it needs
These are the real names of the real files. Nothing in the list below is a roadmap item.
Who the institution is, who works there, and what each of them may touch.
The item library, versioned, reviewed and measured over time.
The paper itself: how it is assembled, when it opens, and who may sit it.
What happened in the room, captured as it happened rather than reconstructed after.
Evidence, not footage. Clean frames are analysed and discarded, never stored.
The exam appears inside the learning system your students already use.
The layer that makes every claim above checkable a year later.
Pool rules draw each candidate a paper from the bank by blueprint: so many items at this difficulty, from that category. The draw is seeded by attempt, so it is reproducible for an appeal and useless to the person in the next seat.
Identity check-in reads the document, matches the face against it, and matches the name against the enrolment, all before the paper opens. Fail it and the attempt does not start; there is no version of this that quietly lets someone through.
Each attempt stores a snapshot of the questions as they were at the moment they were served. Edit an item afterwards and last month’s sitting is unchanged. The paper a candidate disputes is the paper you can still produce.
Results break down by category and by difficulty, and item statistics accumulate across sittings, so a question that everyone gets wrong is visible as a bad item rather than a hard cohort.
An examination platform that cannot receive a cohort from the student system, hand a grade back to the LMS, or let a reseller issue a seat is a platform somebody re-keys by hand at two in the morning.
Register the platform once and Xamina appears as a launchable activity in Canvas, Moodle or Blackboard, with grades posted back through Assignment & Grade Services.
Partners fetch a catalogue and turn a completed payment into a single-use voucher. Every request is HMAC-signed over method, path, body and timestamp inside a five-minute window.
Your systems can be notified the moment something happens, with automatic retries if they are down and a full history of every attempt, not a fire-and-forget POST from inside a request handler.
Candidates, questions and results move in and out as jobs with a progress record and a failure report, rather than a browser upload that times out at row nine thousand.
Modular monolith
NestJS 11, one deployable, module boundaries enforced in code. Easy to run, easy to split later if it ever needs to be.
PostgreSQL + Prisma 6
Tenant scoping and audit writing are client extensions, so no query can forget them.
BullMQ on Redis
Thirteen queues and eleven schedules. Grading, certificates and grade sync retry on their own terms.
Next.js 15 · React 19
Server components for the pages that read, client components only where something actually moves.
Sign in with an institutional address, author a bank, publish an exam and enrol a cohort: the whole loop, on your own content.
