Developed a new Shopware 6 store for a Swiss cycling manufacturer that emphasises community interaction. Customers can upload pictures of their bike designs, register bikes to extend warranties and engage directly with the brand.

Relaunched the online shop of a German tea producer with a content‑first approach. Implemented intuitive content management interfaces tailored to editors, enabling them to maintain and present product information quickly and accurately.

Built a Shopware 6 e‑commerce platform for a German wheel manufacturer. The system includes extensive vehicle search, instant access to TÜV certificates and compatibility lists, user‑generated content for conversions and automated order imports from various channels.

Developed a highly scalable and privacy‑compliant appointment booking platform for government agencies and public authorities. The system supports flexible scheduling, robust data protection and seamless user experiences.

Created a web application connecting non‑profit organisations with volunteers. Organisations can describe themselves and their needs, while volunteers can search for opportunities and contact organisations directly.

Designed an API to receive consumer receipts, identify qualifying products and award instant prizes. The API was built to withstand heavy traffic and integrate seamlessly with promotion campaigns.

Led the relaunch of a Shopware 6 store containing over 150,000 products. Implemented real‑time inventory checks, point‑of‑sale integration, click‑and‑collect functionality, advanced search and rich content pages.

Created an interface to synchronise product and order data between Microsoft Dynamics NAV and Shopware 5. Implemented queueing mechanisms to ensure data integrity and processing speed for real‑time communication.

Designed and developed a SaaS application for resource management and financial planning. Built as a progressive web app using Vue JS and a Symfony backend with an API‑first approach via GraphQL. Integrated Stripe for subscription management and billing.

Developed a business analysis tool to collect, normalise and enrich data from diverse sources and store it in Elasticsearch. Enabled better reporting and decision‑making through centralised search and analytics.
