More about me
I'm a Senior ML Engineer at WooliesX, where I build scalable, high-performance machine learning systems that power real-time decision-making and personalized experiences at scale. With a Master’s in Information Technology from UniMelb, I specialize in bridging the gap between ML research and production engineering, designing robust, efficient, and secure ML applications that drive tangible business impact.
At the core of my work is end-to-end MLOps platform development, including Modelverse, an in-house ML platform that streamlines model versioning, deployment, and collaboration. My expertise spans graph-based recommendation systems, real-time ML inference platforms, and AI-driven automation, leveraging technologies like GNNs, agentic AI, vector databases, and scalable microservices. By integrating cutting-edge ML techniques with production-grade engineering, I deliver highly performant, resilient, and scalable AI solutions that enhance user engagement and operational efficiency.
