Back to original languageAbout Nicolas
Do you have a web application to build, take over, or evolve?
I'm Nicolas, aReact & Symfonydeveloper with 3 years of experience. I mainly work on the **React / TypeScript front-end**, and also on Symfony when the project requires it.
I work on SaaS, internal tools, and business applications. I can join an existing team or take on a clear scope, from development to testing.
What I can handle:
- Front-end interfaces: React, TypeScript, TanStack Query, Zustand, Material UI
- Back-end and APIs: Symfony, PHP, Doctrine ORM, REST API
- Integrations: Stripe, Mercure, Google Calendar, Outlook
- Automated tests: PHPUnit, Behat, Vitest
- Taking over existing applications: bug fixing, refactoring, adding features
My approach is simple:understand what we're building before writing the first line. I prefer to ask a question early rather than fix a wrong choice too late.
In parallel, I am developing **Planiflow**, a workload planning SaaS that combines tasks and calendar to help teams see if they can really say yes to a new project. The product combines product thinking, UX, Symfony / React architecture, calendar synchronization, payment, business logic, and automated testing.
Before that, I worked for two years at Assolia on an agricultural crop rotation simulator: React interfaces, Symfony APIs, business constraints, margin calculations, PHPUnit / Behat tests, and specifications.
Open to React / Symfony missions.
I respond within 24 hours.
