I've architected AI-powered systems and distributed platforms for Qantas Aviations, AZ Digital, Blueeast, and Panda Antivirus. My work combines LLMs, hybrid RAG, knowledge graphs, vector search, cloud platforms, and resilient backend engineering.

At Qantas Aviations, I led a monolithic Rails migration to Kafka and Kubernetes microservices, improving resource utilization by 40% and enabling zero-downtime deployments. I also designed a multi-region active-active payment gateway handling 2M+ transactions per hour and reduced cloud spend by 35%, or $1.2M annually.

At AZ Digital, I designed knowledge graph architecture for multi-tenant AI voice-call systems and developed German-language RAG/CAG pipelines using Claude LLMs and vector embeddings.

Earlier, I designed PostgreSQL architecture supporting 2M+ IoT devices, built machine-learning recommenders, data pipelines, ETL/ELT systems, and decision-ready BI dashboards. I enjoy teamwork and translating business objectives into practical technical architecture and actionable insights.
