About Hasan

I am an engineering leader with 8+ years building and scaling distributed teams across EMEA. Shipped AI-enabled internal platforms and high-throughput services used by thousands of operators, including an agentic LLM system with >90% response accuracy, <10s P50 latency, and 3.4% ticket deflection.
