The success of an enterprise platform relies on the quality of its code and its perfect alignment with business objectives.

We have been TYPO3 experts for over 20 years. Test us!

Custom TYPO3 Extension Development

A third-party software solution never perfectly meets the specific requirements of your business. We design custom TYPO3 extensions, from the frontend to the backend, to integrate complex processes or extend the capabilities of your CMS.

Our Expertise: Perfect Alignment with Your Needs

  • Third-Party System Integration: We develop extensions to connect TYPO3 to your critical tools (ERP, CRM, Inventory Management Systems, payment platforms, etc.) via robust APIs.
  • Specific Backend Functionalities: Creation of custom administration interfaces to simplify the management of complex content or the moderation of data (dynamic forms, reporting dashboards, advanced workflows).
  • High-Performance Frontend Solutions: Development of user-oriented extensions for specific functionalities: interactive product catalogs, simulation tools, secure member areas, etc.

The W3code Guarantee: Respect for Standards

Our quality commitment is total and based on the best practices of the TYPO3 community:

All our developments scrupulously respect the official TYPO3 Coding Standards.

This is not a detail, it is the guarantee of:

  • Maintainability: Clear and standardized code is easy to maintain and debug by any TYPO3 developer.
  • Security: Compliance with standards includes security best practices, thus protecting your platform against common vulnerabilities.
  • Scalability: Your extensions are ready to accompany future major updates of the TYPO3 Core.

TYPO3 Website Design and Development

We don't just deliver lines of code; we build complete web experiences optimized for search engines and users.

From Strategy to Launch

  1. Needs Analysis and Architecture: Defining the site structure, sitemap, and technical architecture (using Composer, server configuration, etc.) to ensure the best possible foundation.
  2. Performance and SEO: Optimizing loading time (advanced use of TYPO3 caching) and semantic structure to ensure optimal SEO.
  3. Training and Skills Transfer: Upon delivery, we provide training for your editorial and technical teams for autonomous operation.

Cutting-Edge Technical Expertise

  • Latest LTS version: We systematically develop on version 13.4 LTS (or the most recent LTS version) to guarantee you the best features and the longest support.
  • "Mobile-First" Approach: Our developments are inherently adaptive and designed for performance on all types of devices.

Code Consulting and Audit

Do you have a project in progress or performance issues on an existing installation? Take advantage of our technical expertise to secure your investment.

  • Performance Audit: Analysis of bottlenecks (database, server, code) and precise recommendations to improve speed and stability.
  • Security Audit: Verification of configuration, dependencies, and custom code to identify and correct potential vulnerabilities.
  • Project Management Assistance (AMO): Technical support to assess the feasibility of complex projects or validate architectural choices.
