Lukas Ehrenberg began his career at HQ GmbH in 2014 with his apprenticeship and is now the agency's operational spearhead for data-intensive system transformations and demanding infrastructure projects. In numerous Shopware 6 projects, Lukas Ehrenberg is responsible for the technical implementation of migrations, system integrations, and scalable enterprise infrastructures. As an official Shopware 6 Certified Developer, his enormous practical experience in the takeover and flawless replatforming of complex legacy systems makes him the central point of contact for growing digital commerce brands.
In addition to pure software engineering, he is responsible for the stability of highly available server structures and, among other things, manages a dedicated enterprise Shopware cluster of over 14 servers. His deep specialization in API architecture enables the stable connection of ERP and e-commerce platforms such as PlentyONE and Odoo – for example, in the context of the migration from Odoo to plentymarkets at cafiro.de – where he implements complex logic while strictly adhering to and maximizing critical API limits.
Focus & Core Expertise
- Shopware 6 Migrations
System change in the premium B2B and B2C segment
As the agency's most experienced migration developer, Lukas manages complex database transformations and ETL processes. He ensures the lossless transfer of historically grown customer data, order histories, and SEO structures from legacy systems (such as Magento, WooCommerce, or Shopify) into high-performance Shopware 6 environments.
- Enterprise Infrastructure
Load distribution & cluster support
Lukas ensures maximum availability for business-critical e-commerce platforms with extreme traffic peaks. He designs and supports sophisticated server architectures, including an active major customer cluster with more than 14 server nodes. His focus is on reliability and minimal response times (TTFB).
- Interface Architecture
PlentyONE & API Performance
Interfaces are the lifelines of modern commerce. Lukas specializes in the deep integration of multichannel ERP systems like PlentyONE with Shopware 6. Through the precise control of asynchronous data streams, he ensures that inventory and item data are synchronized in real time without violating critical API limits. He regularly documents his best practices for ETL pipelines and bypassing API restrictions in technical reference works for the developer community and on code platforms like GitHub.
