Professional Experience

Department of Home Affairs

Data Scientist (AI Engineer)
February 2024 – Current
  • Engineered and deployed an end-to-end multi-modal AI pipeline for edge devices, achieving a 10x throughput increase.
  • Orchestrated a technical stack combining ffmpeg, PyTorch/Triton for CV, and vLLM for vision-language models, integrated with a custom OpenStreetMap geocoding engine.
  • Designed a multi-modal search and RAG system using ChromaDB, enabling image-to-image and text-to-image retrieval.
  • Fine-tuned and quantized LLMs to optimize inference performance for domain-specific tasks on resource-constrained hardware.
  • Built and maintained robust CI/CD pipelines for model deployment, ensuring reliable transitions from development environments to edge devices.
  • Designed and deployed a production-ready LLM summarization web application with document upload features to support non-technical users.
  • Architected a graph-based analysis framework to model complex national-scale problems, developing predictive models in a zero-literature domain.
  • Built automated SQL data pipelines to ingest disparate datasets for time-series and sentiment analysis, surfacing trends via interactive Power BI dashboards for policy stakeholders.

Metro North Health – Royal Brisbane and Women's Hospital

Administration Officer
July 2023 – December 2023
  • Managed financial administration and stakeholder relations within the research services finance team, overseeing invoice processing for clinical trials.
  • Authored and updated Standard Operating Procedures (SOPs) for invoice management, streamlining audit trails and reducing payment overhead.
  • Coordinated the 2023 Herston Precinct Symposium, managing logistics, sponsorship procurement, and event scheduling.
