Project examples.

My work is not limited to cleanup. It spans stabilization, ongoing product development, and building new systems where architecture, data flows, and integrations need to be designed deliberately.

Wunder Software: employee leasing shop and product information system

Built a Laravel- and Docker-based backend platform from scratch, including product data synchronization, distributor integrations, and operational tooling.

Problem
A new commerce system needed more than just a shop backend. It required a project setup, reproducible Docker environments, a distributor-independent product data concept, import and ordering flows with multiple distributors, and a tenant-aware shop system with a clear permissions model.
Approach
I set up the project and Docker workflow, implemented product imports and order flows to and from multiple distributors, built the initial Pimcore solution, and later replaced it with a custom Laravel-based PIM sync. I also created SDK-style plugins for API integrations, a Filament backend for operational functionality, and a user rights system.
Result
The result was a backend system that could evolve beyond an initial PIM choice, integrate multiple external partners reliably, and support ongoing feature development without hardwiring the platform to a single distributor or data source.

LILLYDOO: PIM build, middleware evolution, and Symfony modernization

Led the technical build of a new Pimcore-based PIM, implemented product data imports from legacy systems and complex Excel sources, and modernized the existing Symfony middleware.

Problem
The company needed a new product information system, reliable import paths from inconsistent product data sources, and a clean way to connect that new PIM to an already existing middleware that also had to keep evolving and be modernized technically.
Approach
I built the new PIM system, implemented programmatic product data imports from legacy systems and complex Excel sources, prepared the integration of that new PIM with the existing middleware and adjacent systems, added new functionality to the Symfony application, and upgraded the middleware from Symfony 3 to Symfony 5 including a move to Symfony Flex.
Result
This established a structured product data process around the new PIM and brought the existing middleware onto a modern technical baseline for further evolution and integration work.

gonetto: building a system from scratch

Greenfield development of a backend platform with new functionality, APIs, internal business tooling, and a controlled development workflow from the beginning.

Problem
The platform was still in an early build phase, requirements were taking shape, and large parts of the product still had to be built out. The existing foundation needed to be extended into a stable basis for product development, internal tooling, partner integrations, and key user and admin workflows.
Approach
I continued building out the system through backend architecture work, APIs, data structures, and development environment improvements. That included internal contract management, a customer login area, partner synchronization interfaces, and the admin and backend structures needed for ongoing product development.
Result
The result was a stable and extensible system foundation with clear structures for continued development.

SG-Medien: agency projects across Symfony, CMS, and shop systems

Worked across frequently changing client projects, from new Symfony builds to extensions and fixes in existing CMS and shop systems.

Problem
The work covered a wide range of project contexts, technologies, and requirements. That included new Symfony applications as well as established systems in Shopware, Contao, WordPress, and custom CMS environments that needed new functionality, fixes, and better technical quality.
Approach
I implemented new projects independently, extended existing systems, and adapted quickly to different frameworks, codebases, and project setups while working across PHP, Doctrine, Twig, Sass, JavaScript, jQuery, and related tooling.
Result
This built a broad technical foundation across greenfield work, existing systems, and the practical realities of fast-changing agency projects.
