About Jeanne

Hello, I'm Jeanne 🙂

4 years ago, I created and developed my own mobile application in React Native, with a team of developers that I led long-term. I went through all the stages of a real product: from the idea to the MVP, then to the evolutions, fixes, and optimizations.

Today, after selling the application, I continue to work with my trusted developers, specialized in:
• React Native
• Backend (API, databases)
• Web / admin
• Maintenance and evolutions

Developers can communicate directly with you for simple and effective communication.
On my end, I will support you as a project manager to frame your needs and build a clear, realistic, and well-structured MVP.

Specifically, I help you to:
• define the right features (not too many, not too few)
• structure development (tickets, sprints, priorities)
• organize the project to move forward with confidence
• anticipate technical evolution if the product grows

I can also get involved in UI/UX (user journeys, screens, product logic) so that development starts on solid foundations.

Experience

  • Meetmyengineer
    Fullstack
    December 2025 - Today (6 months)
    I have been working as a freelancer for several years with French and international clients on web and mobile projects ranging from MVP to production applications.

    I have notably participated in the development of:
    • a crowdfunding application
    • a money transfer app (UK → other countries)
    • a dating and events app for university students
    • a platform connecting musical artists with sound engineers

    These experiences have allowed me to work on a wide variety of projects, support product and technical teams, and build reliable, useful, and user-oriented applications.

    Today, I assist companies and startups in creating, evolving, or modernizing their digital products, always with a simple, human, and pragmatic approach.
