I support numerous clients in various areas:

- front-end development (React, JQuery, HTML, CSS, Bootstrap,...)
- development and maintenance of websites or software
- implementation of tracking via tags (Google Analytics, Google Tag Manager, Instagram, Facebook, TikTok, Facebook Conversions API (CAPI)...)
- Agile SCRUM / KANBAN methodology
- CMS: Liferay 7+, Wordpress, Magento, Prestashop
- Tools: Git, GitLab
- DEVOPS: Terraform, Kubernetes, Docker
- ElasticSearch
- CLOUD: AWS
- Authentication: Keycloak (Opensource)

I adapt perfectly to a new environment (complex or not) and I enjoy teamwork.

Looking forward to discussing your projects with you soon!
