Shaping the future with Generative AI and Cloud Engineering
I craft robust AI solutions, architect scalable cloud infrastructures, and build dynamic, full-stack applications. Let's innovate together to create impactful tech that transforms industries.
About Me
I build and deploy scalable, secure Generative AI and Machine Learning systems by combining strong data engineering, model development, and MLOps. I work across healthcare, telecom, and enterprise environments with on-prem, AWS cloud, and hybrid deployments.
🤖 Generative AI & LLM Systems
I specialise in fine-tuning LLMs (SFT, LoRA), building RAG pipelines with Knowledge Graphs and AI agents, and turning them into domain-specific assistants—for example, a cancer research LLM at Cancer Institute NSW and evaluation/fine-tuning work on Google Gemini at Turing.
📊 Data Engineering & MLOps
I design batch and streaming data pipelines (Kinesis, Glue, lakes/lakehouses) and use MLflow, CI/CD, and automated evaluation to keep models versioned, observable, and safely rolled out into production with clear regression checks.
☁️ Cloud, Security & Real-World Impact
Using AWS (SageMaker, Bedrock, EKS, S3) with Docker, Kubernetes, and Terraform, I deliver resilient cloud and hybrid deployments. Highlights include a patented digital-twin compliance platform at AirLabOne and the Jio SecureID authentication ecosystem built for millions of users.
