Case · 01 of 03Featured engagement
Client   Zalando Industry   E-commerce Years   2022 — 2024

"Fashion Forward" — e-commerce platform evolution.

Zalando — leading Berlin-based online fashion retailer — came to us with a legacy Magento platform that was limiting scalability and performance under high traffic loads.

We executed a two-phase architectural transformation: first migrating from Magento to a robust Java-based monolithic platform, then evolving the monolith into a Kubernetes-based microservice architecture — enabling scalable, cloud-native infrastructure for high-traffic e-commerce operations.

Two Magento migrations delivered with zero customer-facing downtime.

Case 02 · Industrial · silicon wafers · 2023

"Silicon Speed" — legacy modernisation.

Leading German supplier of silicon for chip wafers

Legacy IIS and WinForms application creating months-long deployment cycles and limiting operational agility. We modernised the entire application stack by migrating from IIS/WinForms to a cloud-native architecture using Kubernetes microservices and a React.js frontend, implemented through GitOps practices that reduced time-to-market from months to days.

Case 03 · Automotive · car shipping · 2024

"Drive Connected" — AI customer support.

RunBuggy — the only technology platform connecting car shippers and haulers

Manual customer support processes unable to handle complex user requests efficiently. We developed an intelligent chat interface powered by AI agents that can understand user requests and automatically execute specialised tools defined by operators — enabling automated yet personalised customer support at scale.
