• Technical Impact: Actively participating in architectural discussions, challenging the status quo, and proposing new technologies to optimize business solutions.
• Scalability: Ensuring the IT ecosystem is scalable and ready for growing traffic and future market expansions.
• Collaboration: Working closely with operational units and other technical domains to ensure a seamless "Player Journey".
