Do you have a need for Symfony | Laravel | Vue.js | Nuxt.js development?
Look no further.
I am a full stack engineer with over 17 years of experience.
My specialties: PHP, Symfony, Laravel, Vue.js, and Nuxt.js.
I have collaborated with companies such as Médicalib, Carb0n, Groupe Afflelou, Anaxago, and L'Étudiant.
I am able to:
- Design, develop, and maintain features in line with business needs
- Participate in writing detailed technical specifications
- Analyze the impact of product design on the IS technical architecture
- Develop the front-end in Vue, Nuxt, and TypeScript
- Develop the back-end in PHP, Symfony, API Platform, and Laravel
- Design and implement REST APIs (design, versioning, documentation)
- Set up relational databases (PostgreSQL, MySQL, MariaDB)
- Set up CI/CD (GitHub Actions, GitLab CI)
- Design an API-first, microservices, or event-driven software architecture (RabbitMQ, Mercure)
- Write technical documentation
- Perform unit and integration tests to ensure code quality
- Participate in refactoring, continuous improvement, and code review
I also have knowledge of: Docker, Redis, Varnish, Elasticsearch, AWS (Lambda, S3) — as well as automation of business workflows via n8n and integration of AI APIs (Anthropic / OpenAI) into application workflows.
I do not apply best practices dogmatically — I adapt them to the context.
For example, I do not mechanically aim for 100% test coverage.
However, critical paths — those that must not fail in production — are always covered.
The rest is a matter of business priorities.
Maintainable code, stable deliveries, no wasted time.
