BerryBase
Ongoing shop optimisation and performance engineering for the largest maker shop in the German-speaking market — part of the Sertronics group.
The problem
BerryBase is the leading online shop for makers, electronic components and single-board computers in the DACH region — over 20,000 products and three country storefronts for Germany, Switzerland and Austria. The company belongs to the Sertronics group, headquartered in Switzerland with offices in Berlin and Hamburg. The shop, running on Shopware 6, was struggling with mounting performance problems: load times climbing as the catalogue grew, outdated Shopware versions and technical debt from earlier development phases. As an official Raspberry Pi and Arduino retailer selling to a technically demanding audience, fast and reliable shop performance is not a nice-to-have — it is the baseline expectation.
Our approach
We support the BerryBase shop on an ongoing basis, focused on performance optimisation, regular Shopware updates and continuous technical development. Rather than a one-off relaunch, we work in continuous cycles: every iteration measurably improves load times, stability and user experience. The 78% performance gain came from a combination of database optimisation, caching strategy, template refactoring and server-side configuration — all without interrupting live trading.
- Shopware 6 performance audit and systematic optimisation (+78% load-time improvement)
- Regular Shopware updates and security patches across all three country storefronts
- Database optimisation and caching strategy for a 20,000+ product catalogue
- Template refactoring and frontend performance (Core Web Vitals)
- Multi-store configuration for DE, CH (CHF) and AT with country-specific adjustments
- Ongoing feature development and technical support
The impact
The optimisation work improved BerryBase load times by 78% — noticeable on category pages, search results and throughout checkout. Regular Shopware updates keep the shop on a current, secure version. Continuous technical support lets the BerryBase team concentrate on range and marketing while we keep the platform stable and fast. The three country storefronts for DE, CH and AT are maintained in sync, so updates and improvements roll out in parallel.
