Freelance Mission – Mobile & Web Development for BoursoBank (ex-Boursorama)
Category
Mobile App
Client
Boursorama
Duration
1 year
As part of a multi-month freelance mission, I joined the BoursoBank team (formerly Boursorama), a leading online bank in France, to work on their Flutter mobile app, used by over 7 million users. This large-scale project let me grow within a demanding technical environment at the core of a mission-critical, everyday app.
As a Flutter developer, I contributed to the evolution of the mobile app across many areas: redesigning screens, fixing bugs, improving performance and shipping new features, all within a secure, structured environment where code quality and stability were absolute priorities.
I worked closely with product, design and backend teams to ensure UX/UI consistency, frequent releases and on-time delivery.
Alongside mobile work, I leveraged my PHP/Symfony skills on several internal web projects, especially around their banking API. This dual focus gave me a broader view of the bank's application ecosystem and let me contribute from front to backend.
This project confronted me with challenges around scalability, security and reliability at scale. Every change required careful consideration of its impact on millions of active users while maintaining a sustained release cadence.
