Why this program matters

  • Without mastering Domain-Driven Design, 70% of software projects exceed their budget by 50% due to poorly aligned domain models.

  • Teams lose an average of 35% of their time on constant refactoring caused by ignored bounded contexts, resulting in 2x more production incidents according to Gartner studies.

  • In 2024, 65% of senior architects without DDD expertise are excluded from enterprise offers, widening the salary gap by 25%.

  • Your company risks obsolescence against competitors who deliver resilient systems 40% faster.

  • Invest now to turn complexity into a lasting competitive advantage.

Domain-Driven Design (DDD) training objectives

  • Master strategic DDD patterns to align code and business in enterprise settings
  • Develop robust tactical models with aggregates and bounded contexts in professional contexts
  • Implement events and context mapping for certified distributed architectures
  • Design scalable applications via event storming and CQRS in expert training
  • Optimize DDD skills to reduce software complexity in production
  • Deploy DDD solutions tailored to business needs with a focus on maintainability

Program

Domain-Driven Design (DDD) curriculum: 4 modules over 4 days

Module 1 : Strategic DDD: Modeling the domain via ubiquitous language and bounded contexts (event storming, collaborative workshops)

Immersion in event storming to map the business domain with the team, precise definition of the shared ubiquitous language, identification of bounded contexts via interactive workshops on real enterprise cases, creation of context maps to delineate boundaries, practical exercises in refactoring an existing monolith into aligned sub-domains, deliverable of a strategic diagram ready for the overall architecture.

Module 2 : Tactical DDD: Advanced aggregates, entities, and value objects (UML tools, domain-first code)

Design of aggregates with invariants to protect business consistency, fine-grained modeling of entities and value objects with complex invariants, application of repositories and factories in Java or C#, workshops on refactoring legacy code to pure DDD, domain-centric unit tests to validate business rules, production of a complete, testable, and documented domain module, focus on performance in enterprise contexts.

Module 3 : Advanced DDD: CQRS, event sourcing, and integration patterns (Axon Framework, Kafka)

Implementation of CQRS to separate scalable read/write models, mastery of event sourcing with immutable events and projections, use of Axon or EventStore to persist business history, integration via anti-corruption layers and open host services, exercises on Kafka for event propagation between contexts, development of a resilient distributed prototype, analysis of trade-offs for optimal production choices.

Module 4 : DDD in Production: Deployment, Monitoring, and Enterprise Case Studies (Spring Boot, .NET, metrics)

Deployment of a complete DDD application with CI/CD and Docker containers, monitoring of bounded contexts via business-specific metrics, study of real cases from fintech or e-commerce leaders, collaborative refactoring of the 4-day red thread project, DDD compliance audit and evolution plan, delivery of annotated source code and roadmap for enterprise scaling, final evaluation with quiz and defense.

Domain-Driven Design (DDD) training: access and practical arrangements

The Training Domain-Driven Design (DDD) - Modeling Complex Business Domains program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training Domain-Driven Design (DDD) - Modeling Complex Business Domains program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Training Domain-Driven Design (DDD) - Modeling Complex Business Domains program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Our method

How Learni guarantees the quality of your Domain-Driven Design (DDD) training

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
