🎯 Expert Backend PHP Symfony | DDD | CQRS | Microservices | +10 yrs
You have a complex project requiring absolute technical rigor?
I don't just "code features": I build robust, scalable, and maintainable infrastructures designed to last.
Specialist in high technical demand environments, I support startups and scale-ups in designing high-performance backends.
🛠 High-End Expertise (Clean Code & Quality)
My approach is based on technical excellence to ensure code without technical debt:
👉Advanced architectures: Hexagonal (Ports & Adapters), DDD (Domain-Driven Design), CQRS, Event Sourcing...
👉Distributed microservices.
👉Software quality: Strict application of SOLID principles, Clean Code, and TDD (Test Driven Development), CI/CD
👉Performance: Optimization of complex queries, advanced caching, RabbitMQ/Kafka for asynchronous operations.
🚀 Field Experience & Product Impact
I combine an "Engineering" vision with a strong product sensibility (ex-entrepreneur):
Large-scale projects: Critical interventions for Hermès, Orange, Shippeo, and others
Startup Know-how: Launching Lobee & Push (from scratch).
Ecosystem: Complex REST APIs, Microservices, Legacy, Payment Integrations...
🤝 Why work with me?
High-Quality Code: Documented, tested deliveries ready for intensive production.
Architectural Vision: Anticipating tomorrow's needs to avoid costly refactoring.
Total Transparency: Proactive communication and strict adherence to deadlines.
Code is read much more often than it is written. I develop so that your team can take over the project with confidence, today and in 3 years.
