About Virgile

🚨 Are you tired of developers who code before understanding?
If a developer immediately dives headfirst into producing code... it's a very bad sign and a major risk for your project!
  • Has he analyzed the real impact of this expected new feature?
  • Has he produced a specifications document?
  • Will he even dare to tell you that this feature is not feasible before the imposed deadline?
đź’ˇ My expertise: upstream thinking to avoid unpleasant surprises
My approach is radically different. With expertise in Systems Engineering acquired in a highly demanding professional environment, I make it a point of honor to study the mission entrusted to me in detail before writing the first line of code.

🤝 Your future advisor
My role is also to advise and inform you. I am committed to becoming your technical partner, not just a "coder". Based on my analyses, I will be able to advise you on the best path to ensure the sustainability and success of your software solution.

âś… Complete deliverables for total transparency
For maximum transparency and controlled project management, I will provide you with all my analyses before and after completion.

    September 2019 - August 2022 (2 years and 11 months)
    Within the propulsion systems design office, I joined a department whose main mission is to provide software tools to the group's employees.

    Among these software packages is a UML modeling tool (IBM Engineering Rhapsody) used by our architects to model aircraft engines.

    Working in close collaboration with these architects, my main mission was to maintain this tool and make modifications to it so that it best adapted to the architects' use.

    In order to better understand their needs, I was trained in Systems Engineering, particularly in its best practices and UML / SysML modeling.

    Technical:
    - Modification of a Rhapsody software overlay was carried out in JAVA
    - Implementation of tests and automations (JUnit, SikuliX, ...)
    - Use of IBM software components
    - Use of configuration management tools
