Description

I design and evolve complex frontend applications with a strong focus on scalability, performance, and maintainability.

I work on critical, production frontend applications with high demands for robustness and quality.

My approach is based on:

- Solid frontend architecture

- High standards for quality and DX

- Performance and maintainability optimization

Expertise:

- React / Angular / TypeScript

- Large-scale frontend architecture & design systems

- CI/CD (GitLab CI), quality & tooling

- Web performance & scaling

Notable experiences:

- Qonto: development of critical KYC systems used in large-scale production

- Implementation of CI/CD pipelines and shared quality tools

- Improvement of team performance and velocity

I particularly focus on:

- Frontend architecture refactoring

- Application scaling

- Technical team structuring

Typical intervention cases:

- Taking over a frontend that has become difficult to maintain

- Implementing a scalable architecture

- Performance improvements (Core Web Vitals)

- Structuring a design system

- Implementing CI/CD and quality tools

Available for high-stakes technical missions: architecture, scaling, and team structuring.
