Description

Senior Front-End Developer specializing in React, TypeScript, and web accessibility, I help product teams design reliable, inclusive, and sustainable interfaces.

My approach focuses on code quality, user experience, and collaboration with designers, subject matter experts, and backend teams.

I work on both the creation or evolution of design systems and the implementation of best development practices: unit and integration tests (Jest / RTL / Vitest), code reviews, documentation, performance, and structuring modern front-end architectures.

Throughout my assignments (FinTech, HealthTech, EdTech), I have supported teams in redesigning complex applications, improving their accessibility, designing robust large-scale interfaces, and upskilling developers.

I particularly appreciate environments where clarity, communication, and software quality truly matter. If you are looking for someone to strengthen your team, make your front-end reliable, or structure your design system, I would be delighted to discuss it.

April 2024 - October 2025 (1 year and 6 months)

As a Senior Frontend Developer at Resilience, I developed complex interfaces in React and TypeScript, including advanced dashboards, dynamic forms, and reusable components.
I integrated accessibility into the core of development (WAI-ARIA, keyboard navigation), strengthened code quality through unit and integration tests (Jest, React Testing Library), and ensured a high level of performance and reliability in a demanding medical context.

I also participated in mentoring, code reviews, advanced debugging, and continuous improvement of the internal design system, in collaboration with distributed product and technical teams.

SumUp
Frontend Software Engineer
BANKING AND INSURANCE
October 2021 - Today (4 years and 8 months)
Paris, France
As a Frontend Software Engineer within SumUp's (formerly Tiller) POS Lite Ecosystem team, I worked on the integration and management of a large catalog of partner services: delivery solutions (e.g., Deliveroo), accounting tools, banking connectors, and business services.

I developed and maintained React/TypeScript interfaces for activating, configuring, and synchronizing these services within the application. I also handled advanced debugging, code reviews, technical documentation, and coordination with backend teams to ensure the reliability and consistency of integrations.

Accessibility (WAI-ARIA, keyboard navigation), testing (Jest, React Testing Library), and code quality were integral parts of my work. I also collaborated occasionally with the Design System team to maintain visual consistency and component reusability.

This role involved daily work with internationally distributed teams in a dynamic and demanding environment, requiring rigor, communication, and product sense.

As a Senior Developer at Didask, I participated in the migration of a monolithic platform (Flask / Backbone / jQuery) to a modern architecture in React and TypeScript, with a Next.js foundation.
I designed and developed reusable components, complete features, and accessible interfaces, while improving developer experience and design experience (Webpack, ESLint, Storybook).

I also contributed to structuring the code, implementing front-end best practices, and enhancing overall product quality through testing, refactoring, and close collaboration with pedagogical and product teams.
