Lukas Ehrenberg began his career at HQ GmbH in 2014 with his apprenticeship and today is 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 extensive practical experience in taking over and flawlessly replatforming complex legacy systems makes him the central contact for growing digital-commerce brands.
In addition to software engineering itself, he is responsible for the stability of highly available server structures and, among other things, manages a dedicated enterprise Shopware cluster consisting of more than 14 servers. His deep specialization in API architecture enables the stable integration of ERP and e-commerce platforms such as PlentyONE and Odoo – for example as part of the migration from Odoo to plentymarkets at cafiro.de – where he implements complex logic while strictly observing and fully utilizing critical API limits.
Focus & Core Expertise
- Shopware 6 Migrations
System changes in the upper B2B and B2C segment
As the agency’s strongest 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 Balancing & Cluster Management
For business-critical e-commerce platforms with extreme traffic peaks, Lukas ensures maximum availability. He designs and manages sophisticated server architectures, including an active enterprise customer cluster with more than 14 server nodes. His focus is on fail-safe operation 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 such as PlentyONE with Shopware 6. Through precise control of asynchronous data flows, he ensures that inventory and product data are synchronized in real time without violating critical API limits. He regularly documents his best practices for ETL pipelines and working around API restrictions in technical reference materials for the developer community and on code platforms such as GitHub.
