Back to original languageAbout Arnaud
React Developer | TypeScript since 2017
Are you building a SaaS product or a business application and need a senior front-end developer who integrates quickly and delivers code that lasts?
I've been working with startups and product teams for 8 years – from scratch and on existing codebases.
What I develop:
- Complex SaaS dashboards and interfaces
- Business applications with strong business logic
- Back-offices and client areas
- Refactoring and quality upgrades of legacy code
My front-end expertise:
- React / JavaScript (ES6) / TypeScript
- Scalable front-end architecture
- REST API integration
- Performance optimization
- State management (Redux, MobX)
- Data fetching (React Query, SWR)
- Functional and unit testing
- Agile environments (Scrum, sprints)
- Figma mock-up integration
My approach:
Autonomous and product-oriented, I don't just code – I understand business challenges to propose adapted technical solutions. My knowledge of Node.js back-end allows me to collaborate effectively with back-end teams, or to work autonomously on full-stack projects.
