Freelancer profile translated to English.

Description

As a software engineer by training, I have been developing mobile applications with Flutter and Firebase for several years. I designed and launched Cadoia, a collaborative gift list management application available on the App Store and Google Play Store — developed alone, from A to Z.

What this means concretely: I know what it's like to deliver an app to production. Not just coding, but structuring a project, thinking about onboarding, managing updates, publishing on the stores, and evolving the product over time.

I undertake three types of missions:

— MVP from scratch: scoping, design, Flutter + Firebase development, iOS & Android publication

— Project takeover: audit of existing code, adding features, bug fixing

— AI integration: OpenAI or Claude in a mobile app, Cloud Functions, business logic

I use AI (Claude, OpenAI) in my development process — to go faster on certain parts without compromising on quality.

I work alone, via video call, or on-site anywhere in France. No project manager between you and the code: you message me, I reply, and I'm the one who develops.
