- Design scalable systems tailored to business needs
- Implement event-driven patterns with Django and FastAPI
- Optimize read and write performance in production
- Deploy certifiable and maintainable CQRS architectures
Program
CQRS curriculum: 5 modules over 5 days
Module 1 : Theme: Introduction to CQRS with Python (principles, tools, diagrams)
Participants discover the fundamentals of CQRS applied to Python. They analyze real-world business cases, compare traditional and event-driven approaches, and create an initial architecture diagram. Tools include Mermaid diagrams and simple examples with dataclasses. By the end of the day, they produce an initial design deliverable adapted to a professional context.
Module 2 : Theme: Modeling Commands and Queries in CQRS (Django, Pydantic)
The day focuses on clear separation of command and query flows. Learners model aggregates with Django and Pydantic, implement dedicated handlers, and test business scenarios. Practical exercises on databases deliver a first functional prototype ready for the enterprise.
Module 3 : Theme: Events and Bus with FastAPI (projections, outbox pattern)
Trainees integrate an event bus in FastAPI to propagate changes. They build optimized read projections and apply the outbox pattern for reliability. Pair workshops on real cases result in an asynchronous synchronization system ready for production.
Module 4 : Theme: Testing and Validating CQRS Architectures (pytest, monitoring)
This session emphasizes quality and reliability of CQRS code. Participants write comprehensive tests with pytest, simulate load scenarios, and implement monitoring. They deliver an audit report and an automated test suite validating the robustness of their implementation.
Module 5 : Theme: Deploying and Optimizing CQRS in the Enterprise (Docker, performance)
The final day covers moving to production. Learners containerize their solution with Docker, optimize performance, and prepare technical documentation. A complete final project is presented, integrating all acquired skills for a scalable and maintainable professional application.

Hands-on work runs on principles, tools, diagrams, django, pydantic and projections. Those tools come from the CQRS program itself, delivered on site over 5 days, so participants practise on the stack they will use at work.
What can participants do after CQRS training?+
They can master CQRS principles for robust professional applications, develop skills in responsibility separation using Python and design scalable systems tailored to business needs. Those are the stated objectives of the CQRS program at Intermediate level, checked by the end-of-session assessment.
What does the CQRS program cover, day by day?+
Day 1: Theme: Introduction to CQRS with Python (principles, tools, diagrams). Day 2: Theme: Modeling Commands and Queries in CQRS (Django, Pydantic). Day 3: Theme: Events and Bus with FastAPI (projections, outbox pattern). Day 4: Theme: Testing and Validating CQRS Architectures (pytest, monitoring). Day 5: Theme: Deploying and Optimizing CQRS in the Enterprise (Docker, performance). The CQRS program runs over 5 days, delivered on site.
How is CQRS training assessed?+
Assessment relies on daily quizzes on key concepts, ongoing project assessed each day and final presentation before an instructor. Learni issues a completion certificate together with the individual assessment report at the end of the CQRS program, which an L&D team can file as evidence.
How much does CQRS training cost per participant?+
CQRS training costs $5,775 per participant. For an in-company team, the flat rate starts at $10,395 for the whole group, up to 8 people. The detailed quote, sent within one business day, adjusts the amount to the format and how far the syllabus is tailored to your team.
How long does CQRS training take?+
5 days, available live online (US time zones) or on-site at your offices. Half-day tracks spread over several weeks are possible so the team stays operational.
Who pays for CQRS training?+
Most US teams pay directly through their company L&D or training budget. Learni invoices in US dollars and accepts bank transfer (ACH/wire) or card, with volume pricing for teams. A purchase order is welcome.
What do participants need to know before CQRS training?+
Intermediate Python knowledge, experience with Django or Flask, proficiency with relational databases, and familiarity with design patterns.
Is a certificate issued after CQRS training?+
Yes. A Learni completion certificate is issued, along with the individual evaluation report. Learni is a certified training provider and prepares for third-party certifications, but does not award them itself.
Does Learni provide the equipment for CQRS training?+
No. A computer and a stable internet connection are required for each participant. Learni provides the learning platform, the trainer and all course materials.
