About Julien

**Expert PHP/Symfony – Robust technical solutions to grow your project



**

Is your application showing its limits? Do you need an experienced perspective on your architectural choices? Does your team need support with complex technical issues?


With over 20 years of experience in PHP and Symfony, I have assisted numerous companies with their technical challenges, whether it involved architecture redesign, optimization, or team skill development.


My Approach:

Understanding your business and constraints to propose adapted and maintainable solutions. I focus on code quality and architectural choices that will facilitate the future evolution of your project, while also supporting your teams to gain autonomy.


My Typical Missions:
  • Consulting and design of application architectures (microservices, CQRS, Event Sourcing)
  • Redesign of existing applications
  • Performance optimization
  • Technical support and team skill development
  • High value-added development

Technical Stack: PHP, Symfony, API Platform, Docker, PostgreSQL/MySQL, RabbitMQ, Redis [adapt according to your technologies]

Experience

  • Maline Imobilier
    Lead Dev / Architect
    SOFTWARE PUBLISHING
    April 2022 - September 2025 (3 years and 5 months)
    Lyon, France
    Assisting the company in redesigning its IS and internalizing development.

    The applications (outsourced) had reached a point of blockage. A rewrite was decided, as well as the internalization of development teams, starting with the back-end. Upon my arrival, the work had begun, so I conducted an assessment between the requirements and what had been started. I then proposed a shift towards a Micro Service, CQRS, and Event Sourcing architecture. This allows for greater flexibility, facilitates the maintainability of business logic, while combating data inconsistency risks.

    I established the foundation of the solution and supported the skill development of the team (3 developers) for them to adopt the solution. I also acted as a code guarantor to ensure the implemented solution was sustainable, by setting up automated tests and conducting systematic constructive code reviews.

    I also took charge of certain developments:

    Management of data transfer between the two architectures.
    Optimization of certain processes.
    Implementation of monitoring to limit blind spots in code execution.
    Implementation of abstractions and optimizations to facilitate the use of the architecture.
    Optimization of massive data processing in SQL (from 48 hours to 8 hours of processing)

    Stack: PHP 8.1/8.3, Symfony 6/7, PostgreSQL, RabbitMQ, Redis, Behat, Docker.

    My role also led me to take on other responsibilities:

    Primary contact with: Front-end/SysAdmin/PO.
    Involvement in technical aspects for recruitment: defining needs, conducting technical interviews.
    Monitoring developers to facilitate their work while maintaining a high level of quality. Skill development.
    Monitoring and proposing areas for improvement: whether technical or product-related.
