Work Experience

Data Scientist at Cancer Institute NSW

July 1, 2025 - November 1, 2025

Delivered an on-prem privacy-preserving AI Knowledge Assistant for internal PDFs, policies, web pages, and spreadsheets, producing grounded, source-linked answers without external APIs. Built a hybrid FAISS + ontology-driven Knowledge Graph and LangChain/LangGraph agentic flows to plan multi-step retrieval, enforce groundedness checks, and apply safe fallbacks. Deployed with Docker, Kubernetes, Terraform and traced using RAGAS + OpenTelemetry to track quality, citations, and failure modes.

Machine Learning Engineer at AirLabOne

June 1, 2025 - July 1, 2025

Built high-frequency telemetry ingestion for lab devices using AWS IoT Core + Kinesis, landing data to S3 and curating datasets with AWS Glue Data Catalog for traceable analytics. Enabled device health investigation and reporting with Athena + Redshift-backed datasets and service endpoints for operational dashboards. Deployed on Docker + EKS with Terraform and operationalised anomaly detection with MLflow, with monitoring via EventBridge/Lambda/SNS.

LLM - Python Engineer at Turing

August 1, 2024 - August 1, 2025

Evaluated and improved Google Gemini using SFT and RLHF/HFL workflows, focusing on reasoning quality, instruction adherence, and agentic behavior to guide iterative training decisions. Built automated quality gates to validate formatting and policy criteria at scale, improving dataset acceptance consistency. Engineered a high-throughput AWS data workflow (S3, Glue, Spark, Athena, Redshift, dbt) to ingest, validate, and query 15k–20k+ samples/day; containerised pipelines with Docker for reproducibility.

Security Software Engineer at Deneka IT

May 1, 2024 - November 1, 2024

Built ERP & CRM platform capabilities with multi-tenant onboarding and RBAC; implemented JWT-based SSO and RBAC across services.
