BlitzLIS is a multi-tenant, AI-native learning management system built by Altacee for Blitz Learning Technologies. It runs employee training, compliance and customer education for many companies at once, each in its own branded and isolated workspace.

Altacee designed and built it end to end: the FastAPI backend, the PostgreSQL data model with row-level security, search, the AI authoring pipeline, the Next.js web app and the deployment.

How does BlitzLIS keep tenants apart?

In the database. Each request sets the tenant for its transaction, and PostgreSQL row-level security policies on every tenant table refuse rows from any other tenant, so a bug in the API still cannot leak another company's data.

Can BlitzLIS create courses with AI?

Yes. Authors write a brief, optionally upload their own documents, and the generator drafts an outline and lessons. Every AI change arrives as a draft and goes through human review before learners see it.

Which e-learning standards does BlitzLIS support?

SCORM 1.2 and SCORM 2004 import and export, plus cmi5 and AICC import.

How do learners sign in?

With a password hashed using Argon2id, or single sign-on through Google, Microsoft, Okta or SAML, with optional two-factor sign-in by TOTP app or WebAuthn key.

What is BlitzLIS built with?

FastAPI and asynchronous workers, PostgreSQL 16 with pgvector, Meilisearch, Redis, and a Next.js web app.

00> WHAT BLITZLIS IS

A whole learning company, in one system

BlitzLIS (Learning Intelligence System) is a fully branded, multi-tenant learning management system for companies that train employees, run compliance programmes or educate their customers. Each company gets its own workspace on shared infrastructure: its own subdomain, logo, colours, sign-in screen, email identity and certificates. Its learners never see another company, and never see Blitz.

Inside one workspace, six kinds of people work side by side. Learners take courses, sit quizzes and earn certificates. Authors build courses, by hand in a block editor or from a brief and their own documents with AI. Reviewers approve or send back every change before it goes live. Managers assign training and watch their team progress. Admins run users, groups, branding, compliance and reports. Above them all, the platform operator runs every tenant, plan and feature flag.

Altacee designed and built the platform end to end: the FastAPI backend and its asynchronous workers, the PostgreSQL schema with row-level security on every tenant table, search across keywords and meaning, the AI authoring pipeline, the Next.js web app for every role, and the deployment it runs on.

It brings together what usually takes a stack of separate tools (an authoring tool, an LMS, a quiz engine, a certificate generator, a forum and a reporting spreadsheet) in one product that a training company can brand, sell and run for many client companies at once.

02> ISOLATION

One tenant cannot see another, even if the API is wrong

Most multi-tenant products filter by tenant in application code, and one forgotten WHERE clause leaks a client's data to another. BlitzLIS puts the wall in the database. Every request opens a transaction that tells PostgreSQL which tenant it belongs to, and a policy on each table refuses any row from anywhere else.

01A request arrives on a tenant's domain and is authenticated
02The API sets app.tenant_id for that transaction only
03PostgreSQL policies filter every read and reject every foreign write
04Search runs inside the same wall: Meilisearch for words, pgvector for meaning
05Background workers ingest uploads, so material is searchable once it lands

postgres // tenant_isolation.sql

CREATE POLICY lessons_tenant_isolation ON lessons
  USING (tenant_id = current_setting('app.tenant_id', true)::uuid)
  WITH CHECK (tenant_id = current_setting('app.tenant_id', true)::uuid);

-- per request, inside the transaction
SET LOCAL app.tenant_id = '…';

> One policy per tenant table, from the platform's migrations

> HOW IT SHIPPED

// THE CHALLENGE01

What did Blitzlearning need?

An AI-native LMS had to be sold to institutions that share nothing — one tenant seeing another's cohort is the end of the contract — while still feeling instant across a course library nobody wants to browse page by page.

// THE APPROACH02

How did Altacee build Blitzlearning?

Isolation lives in the database, not in application code: Postgres 16 with row-level security per tenant, pgvector alongside it for meaning-based retrieval, Meilisearch for keyword speed, and arq workers ingesting material behind an async FastAPI surface.

// THE OUTCOME03

What did Blitzlearning get?

Tenants share one database and cannot reach each other's rows even if the API is wrong. Course material becomes searchable both by phrase and by intent the moment it finishes uploading.
