Description

E-commerce platforms quickly reach their limits when deviating from standard cases.

My role is to design and develop custom backend functionalities to fill these gaps, automate processes, and ensure the reliability of e-commerce operations.

For over 7 years, I have been involved in projects where native solutions are no longer sufficient.

What I do concretely:

- Development of custom PrestaShop modules

- API Integration (ERP, CRM, logistics, marketplaces...)

- Automation of e-commerce workflows (orders, stock, logistics)

Examples of problems I solve:

- Synchronization between PrestaShop and external tools

- Automation of order processing

- Creation of specific business logic not available natively

Stack: PHP · PrestaShop · MySQL · REST API · Webhooks · Shopify · GraphQL · Docker

🤖 I use AI tools (Claude) to accelerate the development and documentation of my integrations.
