Description

👋 Passionate freelance developer based in Joué-lès-Tours (37), I help businesses

modernize their business processes through web development and automation.

🎯 MY EXPERTISE

I combine three areas of expertise to meet the concrete needs of

businesses:

WordPress & Elementor Pro: Showcase sites, e-commerce, multi-vendor marketplaces
Laravel: Custom business web applications (HR, management, CRM).
Python: Automations, ERP integrations, proprietary system migrations
Cegid Manufacturing PMI: Administration and specific development around the Cegid ERP
PBX 3CX: ERP telephony interfacing, configuration, optimization.

✨ WHAT SETS ME APART

1. BUSINESS APPROACH

I don't just code for the sake of coding: I understand your business problem and propose

adapted, maintainable, and scalable solutions.

2. AUTOMATION & INTEGRATIONS

A specialist in system connections (ERP ↔ Telephony, FTP ↔ Databases,

APIs), I have migrated several RoboTask automations to Python with 100% functional compliance.

3. SECURITY & BEST PRACTICES

Every project integrates security standards (dedicated SQL users, data validation,

detailed logs, robust error handling).

4. EXHAUSTIVE DOCUMENTATION

All my projects are delivered with complete documentation: user guides,

technical documentation, and maintenance procedures.
