Back to original languageAbout Corentin
Freelance developer specializing in PHP Symfony and API architectures, with 8 years of experience, including 4 as a freelancer.
I work on applications with strong business logic: marketplaces, SaaS, HR tools, ERP, CRM. My goal is simple: to design reliable, maintainable, and scalable systems.
Key Expertise:
- API Design (API Platform, REST)
- Backend Architecture (DDD, decoupling, performance)
- Taking over and refactoring existing systems
- Integrating external services (payment, ERP, electronic signature)
I have worked on various topics such as:
- Financial flow management (KYC, payment)
- HR Systems
- Business data flow processing
Comfortable working independently or in a team (PO, QA, UX), I quickly integrate into demanding environments.
Main Stack: Symfony, API Platform, PostgreSQL, Docker, React, Vue.js

It is never easy to take on a short assignment and be effective in real-time.
Corentin managed the implementation of the assignment very well with an extremely positive "service mindset".
I highly recommend him and will not hesitate to call on him again.
