Custom TYPO3 websites built from scratch with future-proof architecture

As a certified TYPO3 developer with Bronze Member status, I have been carrying out complete relaunches and building new, sophisticated websites for over 20 years. From concept development and user experience analysis through to technical implementation, testing and going live – I will support your project comprehensively and transparently.

I begin with a detailed analysis of your existing website, business objectives and target audiences. My TYPO3 websites are GDPR-compliant (where necessary), performance-optimised and built using modern front-end technologies. From small business websites to complex enterprise CMS solutions – I create bespoke websites that are tailored precisely to your needs.

Managing multiple websites from a single central TYPO3 instance – reducing maintenance costs

For companies with multiple websites, subsidiaries or product lines, I implement scalable TYPO3 multisite solutions based on a single central instance. You can manage all websites from a single backend using consistent standards and shared extensions – this significantly reduces maintenance costs.

My multisite architectures allow for customisation of each site, whilst central functions such as user management, extension updates and performance optimisations are shared. Each site can have its own design, content structures and language configurations. I develop solutions for international corporate websites, product websites and e-commerce sites. My architectures are scalable, performance-optimised and compatible with modern deployment strategies.

Reliable TYPO3 upgrades without downtime

I carry out professional TYPO3 upgrades to the latest version and ensure that your website remains technically sound, secure and future-proof. This includes analysing the existing installation, checking for compatibility, customising templates, extensions and configurations, and conducting comprehensive testing before and after the update.

This allows you to benefit from enhanced security, improved performance, more stable system operations and a solid TYPO3 foundation for further enhancements, content customisation and SEO measures. A well-planned upgrade reduces technical risks, improves maintainability and ensures that your website continues to run reliably and efficiently even after a major version upgrade.

Custom APIs for integrating your TYPO3 website with external systems

I seamlessly integrate third-party systems, APIs and external data sources into your TYPO3 website and ensure that all systems communicate reliably with one another. This includes connecting CRM systems to synchronise customer data, newsletter tools for automated campaigns, ERP and accounting systems for product and order data, and PIM systems for the centralised management of your product information.

Customised interfaces to internal applications or external platforms can also be implemented flexibly, for example via REST, JSON, XML or other suitable exchange formats. The aim is to achieve a stable, secure and maintainable integration in which data is transferred correctly, processes are automated and manual tasks are reduced. In this way, TYPO3 becomes the central platform for your web communications and your system landscape, where content, customer data and business processes interlock seamlessly.

A well-designed integration with third-party systems creates genuine long-term added value, as information can be utilised consistently, in real time and without any data disconnects. This makes processes more efficient, transparent and scalable, which is particularly crucial in the context of expanding system landscapes and data-intensive processes.

Professional migration to TYPO3 from other CMS systems without data loss

Where technically feasible, I will handle the complete migration of CMS systems to TYPO3 – ensuring that all content data, structural information, metadata, user accounts and SEO settings are preserved without any loss of data.

I develop a bespoke migration strategy and use automated migration tools combined with manual quality assurance. The migration includes content transfer, structural migration, user migration, SEO migration (URLs, meta tags, redirects), implementation of extensions for functionality, performance optimisation and comprehensive testing phases prior to going live.

Following the migration, I offer support and long-term maintenance. Thanks to my professional migration experience, you can switch to TYPO3 securely, completely and without any problems.

Custom TYPO3 extensions developed to individual requirements

I develop custom TYPO3 extensions that are precisely tailored to your functional requirements and enhance your website with specific features. Whether it’s custom front-end or back-end functionality, complex workflows, automated data processing, specialised form logic or the extension of existing modules: the development is cleanly structured, maintainable, updatable and designed for long-term stability.

This provides you with a TYPO3 solution that integrates flexibly into your existing system landscape, remains technically transparent and can be efficiently developed further to meet future requirements. Custom extension development is particularly useful when standard solutions reach their limits and a precise, scalable implementation is required.

Keeping TYPO3 extensions compatible and customising them 

Before and after a TYPO3 upgrade, I carefully check your extensions for compatibility, functionality and any potential technical conflicts. Not every extension is automatically compatible with the latest version of TYPO3, which is why I analyse dependencies, deprecated functions, interfaces, data structures and any necessary adjustments at an early stage and in a systematic manner.

This will help you minimise downtime, avoid errors during live operation and ensure that your TYPO3 website continues to run smoothly, efficiently and is future-proof following the update. A thorough compatibility check is a key component of any professional TYPO3 project, as it reduces follow-up costs and safeguards the technical quality of your installation in the long term.

Von der Design-Skizze bis zur live TYPO3-Website

I develop websites in TYPO3 based on existing layouts and designs – for example, from Figma, Adobe XD or other design tools – and convert your templates into a clean, high-performance and responsive website structure. In doing so, I ensure a pixel-perfect, technically precise implementation that delivers excellent results both visually and in terms of day-to-day maintenance.

In addition, I take into account structure, usability, semantics, loading times, mobile optimisation and SEO-related aspects, so that your website not only looks good, but can also be found, maintained efficiently and expanded effectively in the long term. Implementation starting from the layout stage is particularly suitable when design and development need to be closely integrated and a high-quality, consistent end result is expected.

Accessibility-compliant TYPO3 websites in accordance with WCAG standards

I optimise the accessibility of your TYPO3 website to ensure that content is accessible, understandable and usable for as many people as possible. This includes an improved semantic structure, meaningful alternative text, optimised keyboard navigation, clear contrasts, intuitive navigation patterns and an overall user-friendly design in line with the latest accessibility standards.

An accessible website not only improves the user experience for people with disabilities, but also enhances the overall quality of your website, broadens the reach of your content and supports professional, modern web communication. Accessibility is therefore not just a technical issue, but an important aspect of usability, quality and digital responsibility.

Fast, high-performance TYPO3 websites

I analyse and improve the performance of your TYPO3 website so that pages load faster, content is delivered more efficiently and users enjoy a noticeably better experience. This includes optimisations relating to caching, image size, code structure, database access, front-end resources and technical processes running in the background.

A faster website results in lower bounce rates, a better user experience on mobile devices and creates better conditions for SEO, conversion optimisation and a strong overall online presence. Performance optimisation is particularly important if your TYPO3 website handles a lot of content, complex functions or a large number of visitors, yet needs to remain fast and stable.

Professional review and evaluation of TYPO3 quotations

I review quotations and proposals for TYPO3 projects in a professional, structured and transparent manner, so that you can better assess technical services and make informed decisions. In doing so, I evaluate the scope, quality, maintainability, potential risks, technical assumptions and the plausibility of individual items in relation to your requirements.

This enables you to identify more quickly whether a quote is truly suited to your project, whether key services have been taken into account, and whether the price is commensurate with the service provided. A professional review of quotes helps you to avoid making the wrong decisions, allocate budgets more effectively, and ensure that TYPO3 projects are built on a solid foundation right from the start.
