Cardmarket.com Tech Stack

Europe's largest trading card game marketplace

Technology, Information and Internet Berlin 51–200 employees Founded 2007 Privately Held

Cardmarket operates a peer-to-peer marketplace for trading card games across Europe, built on a PHP monolith that's actively being decomposed into Go microservices. The API migration and monolith-to-microservices rewrite signal an engineering org moving away from legacy constraints—a pattern typical of platforms that have hit scale (51–200 people, Berlin-based, founded 2007) and need architectural flexibility to keep pace with feature and traffic demands.
