About

Staff Platform Engineer at Commonwealth Bank, building regulated streaming and agentic AI infrastructure — the intersection of Kafka-as-backbone event systems, durable AI agents, and financial services compliance. Over a decade across software engineering, data engineering, and distributed systems. My core toolkit spans Python and Rust, with Rust microservices in production and ongoing Go exploration. I care deeply about system design, async API design, and backend automation — backends that are non-blocking, backpressure-aware, and observable from day one. Streaming & data: AWS MSK, Kinesis, S3, Apache Pulsar, Polars. Durable workflows with Airflow, Celery, and Temporal. Platforms & infra: GitOps-driven multi-tenant platforms on EKS with Kustomize and policy-as-code. Service mesh and sidecar patterns with Istio and Envoy for mTLS, RBAC, and data-plane access control. Docker and Kubernetes underpin everything from Kafka observability to tenant onboarding. Agentic AI & LLMs: Agentic system design with Temporal, MCP, and human-in-the-loop patterns. LLM backends on AWS Bedrock (Claude Sonnet, Titan) and local inference with Ollama. Production RAG systems with Qdrant, Bedrock embeddings, and FastAPI. Rust-native ML with Candle and Burn.
