TYPO3 developer for multi-site, extensions & scalable platforms.
I build and extend Composer-based TYPO3 systems—from site packages, TCA, and editorial content elements to custom extensions, API integrations, technical SEO, and controlled deployments. The projects below show that work in concrete terms.
Three projects, three layers of TYPO3 engineering.
This selection covers platform architecture, custom extension development, and a complete site-package build. Confidential client details are intentionally abstracted while the role and publicly supportable outcomes remain concrete.
Locatec Multi-site Relaunch
Context
67 partner sites needed to be consolidated into a more maintainable TYPO3 structure.
My contribution
Contributed to TYPO3 implementation, reusable content structures, Node.js REST API work, and Docker-based delivery.
Outcome
A shared multi-site foundation for 67 partner presences with more consistent content patterns and update workflows.
TYPO3 Facebook Gallery Extension
Context
Approved photo galleries needed to appear in the CMS without duplicate editorial maintenance.
My contribution
A server-side Graph API client with secure token configuration, pagination, data mapping, cache/fallback strategy, and responsive Fluid output.
Outcome
A controlled TYPO3 integration with less API dependency, explicit error handling, and documented operational behaviour.
This TYPO3 14 Portfolio
Context
A bilingual technical portfolio needed more than fixed page templates: flexible editing, consistent design, and durable SEO foundations.
My contribution
A Composer site package with more than 20 custom content elements, TCA configuration, Fluid/TypoScript, language configuration, structured data, and social metadata.
Outcome
34 indexable German and English pages with reusable components, canonicals, hreflang, a sitemap, and validated JSON-LD.
TYPO3 as a platform, not an isolated CMS.
My TYPO3 work connects CMS development with backend engineering, frontend delivery, APIs, databases, SEO, and DevOps. That lets me work from the content model through to production operations.

DevOps & operations
From multi-site relaunch to custom extension.
The TYPO3 experience was built in professional teams and deepened through my own publicly visible implementation. It covers more than frontend templates: architecture, integrations, editorial models, and operations.
TYPO3 Multi-site Relaunch
- Contributed to a structure serving 67 partner sites.
- Reusable content patterns and TYPO3 implementation.
- Node.js REST API, Docker, Kubernetes, and GitLab CI/CD in the technical environment.
Custom TYPO3 Extension
- Graph API integration for an editorially controlled gallery.
- Token configuration, pagination, mapping, cache, and fallbacks.
- Responsive Fluid output and documented error handling.
Custom TYPO3 14 Site Package
- More than 20 reusable content elements using TCA, Fluid, and TypoScript.
- Bilingual site handling, editorial components, and custom data models.
- Technical SEO with JSON-LD, canonicals, hreflang, and XML sitemaps.
Experience before, during, and after launch.
TYPO3 projects are shaped over time by architecture decisions, editorial usability, upgrade paths, and operational quality. I therefore treat these areas as one system.
Architecture & content model
Page tree, site handling, content structures, and reuse are planned deliberately before implementation.
Editorial usability
Custom content elements reflect real workflows and keep presentation and data consistent.
Extensions with clear ownership
Existing extension, configuration, or custom build is chosen according to maintainability and risk.
Upgrades & reliable operations
Composer, caches, logs, redirects, backups, and controlled deployments are part of implementation.
Detailed TYPO3 evidence.
The case study documents implemented code and operational decisions. The two technical articles explain how I approach architecture, maintainability, and the choice between an existing or custom extension.
