Back to original languageAbout Quentin
For over 5 years, I have been developing and evolving business applications used daily by teams: CRM, ERP, back-offices, SaaS platforms, and internal tools.
My goal: to create reliable, maintainable tools adapted to the company's actual processes.
I mainly work on Symfony back-end projects:
REST APIs, back-offices, internal tools, SaaS platforms.
When necessary, I also develop web interfaces in Vue.js, directly linked to the APIs.
My approach is based on:
• a clear and maintainable architecture
• reliable and scalable code
• particular attention to performance and technical quality
I have worked on various projects: CRM, SaaS, e-commerce, internal tools, and business platforms, in collaboration with technical and product teams.
Main Stack: Symfony, PHP, API Platform, Vue.js
Types of missions: back-end development, APIs, Symfony team reinforcement, business applications
Need to strengthen a Symfony team or build a solid, well-structured web application?
I am available to discuss your project quickly.
