Impact
Infrastructure reliability enabled expansion to 5 new markets (UK, EU, Asia). The compliance achievement and security track record were key to closing Series B investment.

Implemented event-driven architecture with comprehensive audit logging, encryption at rest/transit, automated compliance checks, and multi-region deployment with failover.
