I’m a Senior Software Engineer with progressive experience across backend development, cloud platforms, infrastructure engineering, and AI-enabled software solutions. I started by building reliable backend applications and APIs, then expanded into cloud architecture, automation, container orchestration, observability, and production systems—bringing that same focus to every delivery.

Most recently at Telstra, I lead backend and platform engineering initiatives across distributed systems, cloud infrastructure, deployment automation, and production reliability while helping introduce generative AI into business applications. I design and deliver scalable services and APIs, build AI-enabled features using large language models, retrieval-augmented generation, embeddings, and vector search, and integrate AI services with enterprise systems while addressing security, latency, reliability, and cost. I also build and maintain cloud infrastructure with Terraform, Docker, and Kubernetes, improve CI/CD pipelines and automated testing, and use monitoring and logging practices to investigate incidents, strengthen reliability, and mentor engineers; earlier roles at CommonwealthBank of Australia, WiseTechGlobal, and as a freelance developer shaped my end-to-end approach to secure, scalable engineering and cross-functional collaboration.
