Training program

Module 1Symfony Architecture: Advanced Services and Dependency Injection (DI, Events, Bundles)

Dive into configuring complex Symfony services, implement dependency injection for decoupled architectures, create custom events with EventDispatcher, develop a first reusable bundle on a real enterprise case, perform practical exercises with autowiring and scoping, produce an architecture diagram and a tested functional deliverable in group.

Module 2Symfony APIs: REST and GraphQL with API Platform (JWT, Serializers, Documentation)

Build high-performance APIs by installing API Platform on Symfony, configure advanced CRUD operations with filters and pagination, integrate JWT authentication for enterprise security, generate automatic Swagger documentation, apply to a red thread project with real data, test endpoints via Postman, optimize serializers for fast responses, and produce a deployable API.

Module 3Symfony Performance: Doctrine Optimization and Caching (Profiler, Redis, Queries)

Analyze bottlenecks with Symfony Profiler, optimize Doctrine queries via advanced DQL and custom repositories, implement Redis and HTTP caching to accelerate apps, measure gains on large datasets, perform refactoring exercises on legacy code, configure connection pools, generate performance reports, and create a concrete production optimization plan.

Module 4Symfony Security: Guards, Voters, and Advanced Protection (CSRF, OWASP, Firewalls)

Strengthen your apps with Symfony security guards and access voters, implement CSRF protection and rate limiting, audit OWASP vulnerabilities via dedicated bundles, configure multiple firewalls for APIs and web, test simulated attacks in practical workshops, apply to the red thread project with secure logs, produce a complete security audit and certified enterprise recommendations.

Module 5Symfony Testing and Deployment: PHPUnit, CI/CD, and Production (Docker, GitHub Actions)

Master PHPUnit for unit, functional, and end-to-end tests in Symfony, integrate Behat for BDD, configure CI/CD pipelines with GitHub Actions and Docker, deploy to staging then production environments, simulate zero-downtime rollouts, review the red thread project in collective code review, generate coverage badges, and produce a deployment playbook ready for the team.
