About Nathan

📌 Why is a solid mobile architecture crucial?

In a mobile project, 50% of technical costs appear after launch, often linked to poorly anticipated technical debt (source: McKinsey, Stripe Developer Report).
A well-thought-out architecture from the start means:

✅ More maintainable and scalable code
✅ Fewer bugs and better stability
✅ Faster developer onboarding
✅ Reduced timelines for adding new features

Too often, Flutter projects start fast... and then slow down drastically after a few months due to a fragile technical foundation. My role? To help you avoid that.


👨‍💻 My Background

Flutter Architect / Developer for 5 years, I have:

➡️ Led the technical design and development of 3 mobile applications in the last 2 years for communication and data security,
➡️ Implemented robust architectures (Clean Architecture, BLoC, Riverpod...) in teams ranging from 2 to 10 developers
➡️ Worked in agile mode with designers, PMs, and backend developers to deliver performant, scalable, and maintainable apps

I am also comfortable with:

➡️ The Firebase environment, REST/GraphQL, CI/CD, Native Android / IOS
➡️ Refactoring struggling projects, migrations to better structures
➡️ Technical mentoring of junior and intermediate developers


🚀 Let's work together!

Do you have a Flutter project in progress or to launch?
I'll help you lay a solid foundation, avoid common pitfalls, and ensure the technical success of your app.
📩 Let's talk about it — I'm always up for discussing an ambitious project (or saving a struggling one!).
