Learning objectives

  • Master advanced Doctrine ORM mappings for complex professional entities
  • Develop customized repositories optimizing enterprise queries
  • Implement DQL and QueryBuilder for certified database performance
  • Manage advanced relationships and associations with Doctrine ORM in production
  • Optimize caching, lazy loading, and migrations for scalable applications
  • Design robust persistence architectures tailored to business needs

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1Advanced Mappings: Configure Complex Entities with Doctrine ORM (annotations, XML, YAML, inheritance)

Dive into customizing Doctrine ORM entities via advanced annotations, XML, and YAML, handling class inheritance and custom types. Apply these techniques to a real e-commerce project with multi-table mapping exercises, generate automated schemas, test validity with integrated PHPUnit, and produce a deliverable: production-ready entity bundle and complete documentation.

Module 2Repositories and QueryBuilder: Build Performant Queries with Doctrine ORM (DQL, hydration)

Build custom repositories extending Doctrine ORM, master QueryBuilder for complex joins and aggregations, write native DQL for edge cases, optimize partial hydration on large datasets. Practice on Symfony REST API with infinite pagination, analyze query profiles via WebProfiler. Deliverable: reusable repository boosting performance by 50% on existing code.

Module 3Advanced Relationships: Model Doctrine ORM Associations (many-to-many, cascades, proxies)

Model complex bidirectional relationships like many-to-many with extra fields and automated cascades in Doctrine ORM, manage lazy and eager loading proxies to avoid N+1 queries, implement ownership and ordering. Test on multi-tenant SaaS cases with data fixtures, debug with doctrine:query-sql, produce interconnected entity graph and team relationship optimization guide.

Module 4Performance and Caching: Accelerate Doctrine ORM (second level cache, result cache, fragments)

Boost Doctrine ORM via second-level caching with Redis and Memcached, configure result cache on hot queries and fragments for partial views, measure gains with Blackfire profiler. Apply strategic lazy loading on mobile apps, migrate existing cache without downtime, exercises on high-load traffic. Deliverable: documented caching strategy reducing DB latency by 70% in production.

Module 5Migrations and Pro Tools: Maintain Doctrine ORM Schemas (migrations, fixtures, console)

Automate zero-downtime migrations with DoctrineMigrationsBundle, generate advanced fixtures via Faker and Alice for E2E tests, customize console commands for bulk operations, manage multi-environment DB versioning, integrate CI/CD GitHub Actions. Practice secure rollback on prod-like setup, finalize red thread project with full audit, receive scalable migrations template for your company.

Evaluation method

  • Expert multiple-choice quiz on Doctrine ORM mappings and performance
  • Assessment via practical challenges and code review
  • Defense of red thread project with measured optimization

Learning method

  • Sessions led by Doctrine experts on production missions
  • Intensive hands-on labs on Symfony and real business cases
  • Evolving red thread project over 5 days
  • Detailed course materials, slides, and Git repository provided

Our method

Training quality, guaranteed at every step

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.
