Dimuthu Wickramanayake

AI Platform & Agent Infrastructure Engineer

AI platform engineer with 7+ years operating production systems on GCP and AWS. I ship LLM infrastructure that an engineering team depends on daily — two Model Context Protocol servers used in production by 10+ engineers, and a 50-user LangGraph assistant hardened with fail-closed data isolation, approval-gated writes, and quota-aware concurrency control. Underneath sits consumer-scale platform work: Kubernetes services sustaining 3,000+ RPS for 50M+ users, and a 35% quarter-over-quarter cut in critical incidents.
