🛠️ I am able to:
- Design and develop solutions aligned with your business needs.

- Refactor legacy code.
- Optimize code and performance
- Provide support and mentoring to development teams
- Write technical documentation

💻 I also have knowledge of git, docker, Sylius, infra as code, AWS, RabbitMQ, Scrum, Kanban, Jira, Trello…

🔧 I have a particular interest in craft practices:
- Clean code
- Test-Driven Development (TDD)
- Domain Driven Design (DDD)
- Hexagonal architecture
- Software Craftsmanship

💡 Nevertheless, I maintain a pragmatic approach to these practices.

👨‍💻👩‍💻 I enjoy working in a team, regularly practicing pair/mob programming.
