Back to original languageAbout Max
Do you have an ERP, CRM, or internal business tool to evolve, stabilize, or migrate? That's exactly where I come in.
Backend PHP developer with over 4 years of experience on complex business applications, I take on projects with strong business logic: field intervention management, billing, scheduling, activity monitoring, digitalization of paper processes, integration of external APIs.
What I can concretely bring you:
Taking over and evolving an existing ERP/CRM, even on legacy code
Developing new business features from A to Z
Performance optimization (SQL queries, loading times)
Application migration and implementation of best practices (Git, Docker, tests)
Notably, I spent over 2 years on the internal ERP of a construction company (Iréa Ascenseurs), completely autonomously, throughout the entire cycle — from PHP migration to Docker to the development of critical business modules.
Main Stack: PHP · Symfony · MySQL/MariaDB · JavaScript · Docker · Git
Based in Île-de-France — remote with occasional travel possible.
